Fixed

• Upgrade brick/math to support versions ^0.14 to ^0.17; fixed in #638.
• Add support for brick/math ^0.18.

Fixed

• Remove explicit (int) cast to avoid float-string cast warnings in PHP 8.5.
• Bump the lowest supported version of brick/math to ^0.8.16 from ^0.8.8. ramsey/uuid had been using BigInteger::toBytes() in UnixTimeGenerator (for version 7 UUIDs) since v4.6.0, but it wasn't added to brick/math until v0.8.16.

Fixed

• The original 4.7.2 tag accidentally pointed to a commit in the 5.x branch. I have replaced the 4.7.2 tag with a new tag that points to the correct commit, but I am creating this tag to help notify users and automated processes who might have already updated to the bad 4.7.2 tag (#487).

Fixed

• Amend Psalm assertion syntax on Uuid::isValid() to prevent incorrect type inference (#486).
• Re-tagged with the correct commit hash, since the first tag was pointing to a commit in the 5.x branch.

Fixed

• Allow the use of ramsey/collection ^2.0 with ramsey/uuid.

Added

• Add Uuid::fromHexadecimal() and UuidFactory::fromHexadecimal(). These methods are not required by the interfaces.

Fixed

• Ignore MAC addresses consisting of all zeroes (i.e., 00:00:00:00:00:00).

Added

• Add support for version 8, Unix Epoch time UUIDs, as defined in [draft-ietf-uuidrev-rfc4122bis-00, section 5.8][version8]. While still an Internet-Draft, version 8 is stable and unlikely to change in any way that breaks compatibility.
  • Use Ramsey\Uuid\Uuid::uuid8() to generate version 8 UUIDs.
  • Version 8 UUIDs are of type Ramsey\Uuid\Rfc4122\UuidV8.
  • The constant Ramsey\Uuid\Uuid::UUID_TYPE_CUSTOM exists for version 8 UUIDs.

Fixed

• Ensure monotonicity of version 7 UUIDs.

Fixed

• Update RFC 4122 validator to recognize version 6 and 7 UUIDs.

Added

• Promote version 6, reordered time UUIDs from the Nonstandard namespace to the Rfc4122 namespace. Version 6 UUIDs are defined in [draft-ietf-uuidrev-rfc4122bis-00, section 5.6][version6]. While still an Internet-Draft version 6 is stable and unlikely to change in any way that breaks compatibility.
• Add support for version 7, Unix Epoch time UUIDs, as defined in [draft-ietf-uuidrev-rfc4122bis-00, section 5.7][version7]. While still an Internet-Draft, version 7 is stable and unlikely to change in any way that breaks compatibility.
  • Use Ramsey\Uuid\Uuid::uuid7() to generate version 7 UUIDs.
  • Version 7 UUIDs are of type Ramsey\Uuid\Rfc4122\UuidV7.
  • The constant Ramsey\Uuid\Uuid::UUID_TYPE_UNIX_TIME exists for version 7 UUIDs.
• Add Ramsey\Uuid\Converter\Time\UnixTimeConverter and Ramsey\Uuid\Generator\UnixTimeGenerator to support version 7 UUID generation.
• Add support for [max UUIDs][] through Ramsey\Uuid\Uuid::MAX and Ramsey\Uuid\Rfc4122\MaxUuid.

Changed

• The lowest version of brick/math allowed is now ^0.8.8.

Deprecated

The following will be removed in ramsey/uuid 5.0.0:

• Ramsey\Uuid\Nonstandard\UuidV6 is deprecated in favor of Ramsey\Uuid\Rfc4122\UuidV6.
• Ramsey\Uuid\Uuid::UUID_TYPE_PEABODY; use Ramsey\Uuid\Uuid::UUID_TYPE_REORDERED_TIME instead.

Fixed

• For Ramsey\Uuid\Uuid::isValid(), Psalm now asserts the UUID is a non-empty-string when it is valid.
• Nil UUIDs are properly treated as RFC 4122 variants, and getVariant() now returns a 2 when called on a nil UUID.

Changed

• Allow brick/math 0.10.
• Remove dev dependency to moontoast/math.
• Un-deprecate UuidInterface::getUrn().

Deprecated

The following will be removed in ramsey/uuid 5.0.0:

• Ramsey\Uuid\Generator\RandomLibAdapter

Changed

• Remove support for PHP 7.2, 7.3, and 7.4. This is not a BC break, since Composer will do the right thing for your environment and select a compatible version of this library.
• Require ext-ctype extension. For applications that run in environments where the ext-ctype is not present, please require a polyfill, such as symfony/polyfill-ctype.
• Use iterable<UuidBuilderInterface> instead of BuilderCollection types.
• Use iterable<NodeProviderInterface> instead of NodeProviderCollection types.

Deprecated

The following will be removed in ramsey/uuid 5.0.0:

• Ramsey\Uuid\Builder\BuilderCollection
• Ramsey\Uuid\Provider\Node\NodeProviderCollection
• Dependency on ramsey/collection

Fixed

• Support valid UUIDs in uppercase in LazyUuidFromString.

Fixed

• Switch back to ^8.0 in the PHP version requirement.

Fixed

• Indicate support for PHP 8.1, using ~8.1.0 to prevent installations on 8.2 until the library is ready.

Fixed

• Fix soft BC break with Uuid::fromString() signature. The change from string to non-empty-string on the parameter annotation introduced a BC break for those using static analysis tools. This release reverts this change and provides an assertion to guard against empty strings. See ramsey/uuid#383.

Added

• Add Ramsey\Uuid\Exception\UuidExceptionInterface for all ramsey/uuid exceptions to implement. See ramsey/uuid#340.

Fixed

• Fix serialization of UUIDs. See ramsey/uuid#361.

Fixed

• Switch back to ^8.0 in the PHP version requirement.

Fixed

• Lock 4.1.x to ~8.0.0 to indicate it does not support PHP 8.1.

Fixed

• Allow use of brick/math version 0.9

Changed

• Improve performance of Uuid::fromString(), Uuid::fromBytes(), UuidInterface#toString(), and UuidInterface#getBytes(). See PR #324 for more information.

Fixed

• Switch back to ^8.0 in the PHP version requirement.

Fixed

• Lock 4.0.x to ~8.0.0 to indicate it does not support PHP 8.1.

Fixed

• Fix collection deserialization errors due to upstream allowed_classes being set to false. For details, see ramsey/uuid#303 and ramsey/collection#47.

Added

• Add support for version 6 UUIDs, as defined by http://gh.peabody.io/uuidv6/, including the static method Uuid::uuid6(), which returns a Nonstandard\UuidV6 instance.
• Add ability to generate version 2 (DCE Security) UUIDs, including the static method Uuid::uuid2(), which returns an Rfc4122\UuidV2 instance.
• Add classes to represent each version of RFC 4122 UUID. When generating new UUIDs or creating UUIDs from existing strings, bytes, or integers, if the UUID is an RFC 4122 variant, one of these instances will be returned:
  • Rfc4122\UuidV1
  • Rfc4122\UuidV2
  • Rfc4122\UuidV3
  • Rfc4122\UuidV4
  • Rfc4122\UuidV5
  • Rfc4122\NilUuid
• Add classes to represent version 6 UUIDs, GUIDs, and nonstandard (non-RFC 4122 variant) UUIDs:
  • Nonstandard\UuidV6
  • Guid\Guid
  • Nonstandard\Uuid
• Add Uuid::fromDateTime() to create version 1 UUIDs from instances of \DateTimeInterface.
• The \DateTimeInterface instance returned by UuidInterface::getDateTime() (and now Rfc4122\UuidV1::getDateTime()) now includes microseconds, as specified by the version 1 UUID.
• Add Validator\ValidatorInterface and Validator\GenericValidator to allow flexibility in validating UUIDs/GUIDs.
  • The default validator continues to validate UUID strings using the same relaxed validation pattern found in the 3.x series of ramsey/uuid.
  • Introduce Rfc4122\Validator that may be used for strict validation of RFC 4122 UUID strings.
  • Add ability to change the default validator used by Uuid through FeatureSet::setValidator().
  • Add getValidator() and setValidator() to UuidFactory.
• Add Provider\Node\StaticNodeProvider to assist in setting a custom static node value with the multicast bit set for version 1 UUIDs.
• Add the following new exceptions:
  • Exception\BuilderNotFoundException - Thrown to indicate that no suitable UUID builder could be found.
  • Exception\DateTimeException - Thrown to indicate that the PHP DateTime extension encountered an exception/error.
  • Exception\DceSecurityException - Thrown to indicate an exception occurred while dealing with DCE Security (version 2) UUIDs.
  • Exception\InvalidArgumentException - Thrown to indicate that the argument received is not valid. This extends the built-in PHP \InvalidArgumentException, so there should be no BC breaks with ramsey/uuid throwing this exception, if you are catching the PHP exception.
  • Exception\InvalidBytesException - Thrown to indicate that the bytes being operated on are invalid in some way.
  • Exception\NameException - Thrown to indicate that an error occurred while attempting to hash a namespace and name.
  • Exception\NodeException - Thrown to indicate that attempting to fetch or create a node ID encountered an error.
  • Exception\RandomSourceException - Thrown to indicate that the source of random data encountered an error.
  • Exception\TimeSourceException - Thrown to indicate that the source of time encountered an error.
  • Exception\UnableToBuildUuidException - Thrown to indicate a builder is unable to build a UUID.
• Introduce a Builder\FallbackBuilder, used by FeatureSet to help decide whether to return a Uuid or Nonstandard\Uuid when decoding a UUID string or bytes.
• Add Rfc4122\UuidInterface to specifically represent RFC 4122 variant UUIDs.
• Add Rfc4122\UuidBuilder to build RFC 4122 variant UUIDs. This replaces the existing Builder\DefaultUuidBuilder, which is now deprecated.
• Introduce Math\CalculatorInterface for representing calculators to perform arithmetic operations on integers.
• Depend on brick/math for the Math\BrickMathCalculator, which is the default calculator used by this library when math cannot be performed in native PHP due to integer size limitations. The calculator is configurable and may be changed, if desired.
• Add Converter\Number\GenericNumberConverter and Converter\Time\GenericTimeConverter which will use the calculator provided to convert numbers and time to values for UUIDs.
• Introduce Type\Hexadecimal, Type\Integer, Type\Decimal, and Type\Time for improved type-safety when dealing with arbitrary string values.
• Add a Type\TypeInterface that each of the ramsey/uuid types implements.
• Add Fields\FieldsInterface and Rfc4122\FieldsInterface to define field layouts for UUID variants. The implementations Rfc4122\Fields, Guid\Fields, and Nonstandard\Fields store the 16-byte, binary string representation of the UUID internally, and these manage conversion of the binary string into the hexadecimal field values.
• Introduce Builder\BuilderCollection and Provider\Node\NodeProviderCollection. These are typed collections for providing builders and node providers to Builder\FallbackBuilder and Provider\Node\FallbackNodeProvider, respectively.
• Add Generator\NameGeneratorInterface to support alternate methods of generating bytes for version 3 and version 5 name-based UUID. By default, ramsey/uuid uses the Generator\DefaultNameGenerator, which uses the standard algorithm this library has used since the beginning. You may choose to use the new Generator\PeclUuidNameGenerator to make use of the new uuid_generate_md5() and uuid_generate_sha1() functions in ext-uuid version 1.1.0.

Changed

• Set minimum required PHP version to 7.2.
• This library now works on 32-bit and 64-bit systems, with no degradation in functionality.
• By default, the following static methods will now return specific instance types. This should not cause any BC breaks if typehints target UuidInterface:
  • Uuid::uuid1 returns Rfc4122\UuidV1
  • Uuid::uuid3 returns Rfc4122\UuidV3
  • Uuid::uuid4 returns Rfc4122\UuidV4
  • Uuid::uuid5 returns Rfc4122\UuidV5
• Accept Type\Hexadecimal for the $node parameter for UuidFactoryInterface::uuid1(). This is in addition to the int|string types already accepted, so there are no BC breaks. Type\Hexadecimal is now the recommended type to pass for $node.
• Out of the box, Uuid::fromString(), Uuid::fromBytes(), and Uuid::fromInteger() will now return either an Rfc4122\UuidInterface instance or an instance of Nonstandard\Uuid, depending on whether the input contains an RFC 4122 variant UUID with a valid version identifier. Both implement UuidInterface, so BC breaks should not occur if typehints use the interface.
• Change Uuid::getFields() to return an instance of Fields\FieldsInterface. Previously, it returned an array of integer values (on 64-bit systems only).
• Uuid::getDateTime() now returns an instance of \DateTimeImmutable instead of \DateTime.
• Make the following changes to UuidInterface:
  • getHex() now returns a Type\Hexadecimal instance.
  • getInteger() now returns a Type\Integer instance. The Type\Integer instance holds a string representation of a 128-bit integer. You may then use a math library of your choice (bcmath, gmp, etc.) to operate on the string integer.
  • getDateTime() now returns \DateTimeInterface instead of \DateTime.
  • Add __toString() method.
  • Add getFields() method. It returns an instance of Fields\FieldsInterface.
• Add the following new methods to UuidFactoryInterface:
  • uuid2()
  • uuid6()
  • fromDateTime()
  • fromInteger()
  • getValidator()
• This library no longer throws generic exceptions. However, this should not result in BC breaks, since the new exceptions extend from built-in PHP exceptions that this library previously threw.
  • Exception\UnsupportedOperationException is now descended from \LogicException. Previously, it descended from \RuntimeException.
• Change required constructor parameters for Uuid:
  • Change the first required constructor parameter for Uuid from array $fields to Rfc4122\FieldsInterface $fields.
  • Add Converter\TimeConverterInterface $timeConverter as the fourth required constructor parameter for Uuid.
• Change the second required parameter of Builder\UuidBuilderInterface::build() from array $fields to string $bytes. Rather than accepting an array of hexadecimal strings as UUID fields, the build() method now expects a byte string.
• Add Converter\TimeConverterInterface $timeConverter as the second required constructor parameter for Rfc4122\UuidBuilder. This also affects the now-deprecated Builder\DefaultUuidBuilder, since this class now inherits from Rfc4122\UuidBuilder.
• Add convertTime() method to Converter\TimeConverterInterface.
• Add getTime() method to Provider\TimeProviderInterface. It replaces the currentTime() method.
• Provider\Node\FallbackNodeProvider now accepts only a Provider\Node\NodeProviderCollection as its constructor parameter.
• Provider\Time\FixedTimeProvider no longer accepts an array but accepts only Type\Time instances.
• Provider\NodeProviderInterface::getNode() now returns Type\Hexadecimal instead of string|false|null.
• Converter/TimeConverterInterface::calculateTime() now returns Type\Hexadecimal instead of array. The value is the full UUID timestamp value (count of 100-nanosecond intervals since the Gregorian calendar epoch) in hexadecimal format.
• Change methods in NumberConverterInterface to accept and return string values instead of mixed; this simplifies the interface and makes it consistent.
• Generator\DefaultTimeGenerator no longer adds the variant and version bits to the bytes it returns. These must be applied to the bytes afterwards.
• When encoding to bytes or decoding from bytes, OrderedTimeCodec now checks whether the UUID is an RFC 4122 variant, version 1 UUID. If not, it will throw an exception—InvalidArgumentException when using OrderedTimeCodec::encodeBinary() and UnsupportedOperationException when using OrderedTimeCodec::decodeBytes().

Deprecated

The following functionality is deprecated and will be removed in ramsey/uuid 5.0.0.

• The following methods from UuidInterface and Uuid are deprecated. Use their counterparts on the Rfc4122\FieldsInterface returned by Uuid::getFields().
  • getClockSeqHiAndReservedHex()
  • getClockSeqLowHex()
  • getClockSequenceHex()
  • getFieldsHex()
  • getNodeHex()
  • getTimeHiAndVersionHex()
  • getTimeLowHex()
  • getTimeMidHex()
  • getTimestampHex()
  • getVariant()
  • getVersion()
• The following methods from Uuid are deprecated. Use the Rfc4122\FieldsInterface instance returned by Uuid::getFields() to get the Type\Hexadecimal value for these fields. You may use the new Math\CalculatorInterface::toIntegerValue() method to convert the Type\Hexadecimal instances to instances of Type\Integer. This library provides Math\BrickMathCalculator, which may be used for this purpose, or you may use the arbitrary-precision arithmetic library of your choice.
  • getClockSeqHiAndReserved()
  • getClockSeqLow()
  • getClockSequence()
  • getNode()
  • getTimeHiAndVersion()
  • getTimeLow()
  • getTimeMid()
  • getTimestamp()
• getDateTime() on UuidInterface and Uuid is deprecated. Use this method only on instances of Rfc4122\UuidV1 or Nonstandard\UuidV6.
• getUrn() on UuidInterface and Uuid is deprecated. It is available on Rfc4122\UuidInterface and classes that implement it.
• The following methods are deprecated and have no direct replacements. However, you may obtain the same information by calling UuidInterface::getHex() and splitting the return value in half.
  • UuidInterface::getLeastSignificantBitsHex()
  • UuidInterface::getMostSignificantBitsHex()
  • Uuid::getLeastSignificantBitsHex()
  • Uuid::getMostSignificantBitsHex()
  • Uuid::getLeastSignificantBits()
  • Uuid::getMostSignificantBits()
• UuidInterface::getNumberConverter() and Uuid::getNumberConverter() are deprecated. There is no alternative recommendation, so plan accordingly.
• Builder\DefaultUuidBuilder is deprecated; transition to Rfc4122\UuidBuilder.
• Converter\Number\BigNumberConverter is deprecated; transition to Converter\Number\GenericNumberConverter.
• Converter\Time\BigNumberTimeConverter is deprecated; transition to Converter\Time\GenericTimeConverter.
• The classes for representing and generating degraded UUIDs are deprecated. These are no longer necessary; this library now behaves the same on 32-bit and 64-bit systems.
  • Builder\DegradedUuidBuilder
  • Converter\Number\DegradedNumberConverter
  • Converter\Time\DegradedTimeConverter
  • DegradedUuid
• The Uuid::UUID_TYPE_IDENTIFIER constant is deprecated. Use Uuid::UUID_TYPE_DCE_SECURITY instead.
• The Uuid::VALID_PATTERN constant is deprecated. Use Validator\GenericValidator::getPattern() or Rfc4122\Validator::getPattern() instead.

Removed

• Remove the following bytes generators and recommend Generator\RandomBytesGenerator as a suitable replacement:
  • Generator\MtRandGenerator
  • Generator\OpenSslGenerator
  • Generator\SodiumRandomGenerator
• Remove Exception\UnsatisfiedDependencyException. This library no longer throws this exception.
• Remove the method Provider\TimeProviderInterface::currentTime(). Use Provider\TimeProviderInterface::getTime() instead.

Added

• Add ValidatorInterface::getPattern() to return the regular expression pattern used by the validator.
• Add v6() helper function for version 6 UUIDs.

Changed

• Set the pattern constants on validators as private. Use the getPattern() method instead.
• Change the $node parameter for UuidFactoryInterface::uuid6() to accept null or Type\Hexadecimal.
• Accept Type\Hexadecimal for the $node parameter for UuidFactoryInterface::uuid1(). This is in addition to the int|string types already accepted, so there are no BC breaks. Type\Hexadecimal is now the recommended type to pass for $node.

Removed

• Remove currentTime() method from Provider\Time\FixedTimeProvider and Provider\Time\SystemTimeProvider; it had previously been removed from Provider\TimeProviderInterface.

Added

• Introduce Builder\BuilderCollection and Provider\Node\NodeProviderCollection.

Changed

• Builder\FallbackBuilder now accepts only a Builder\BuilderCollection as its constructor parameter.
• Provider\Node\FallbackNodeProvider now accepts only a Provider\Node\NodeProviderCollection as its constructor parameter.
• Provider\Time\FixedTimeProvider no longer accepts an array but accepts only Type\Time instances.

Added

• Add a Type\TypeInterface that each of the ramsey/uuid types implements.
• Support version 6 UUIDs; see http://gh.peabody.io/uuidv6/.

Changed

• Rename Type\IntegerValue to Type\Integer. It was originally named IntegerValue because static analysis sees Integer in docblock annotations and treats it as the native int type. Integer is not a reserved word in PHP, so it should be named Integer for consistency with other types in this library. When using it, a class alias prevents static analysis from complaining.
• Mark Guid\Guid and Nonstandard\Uuid classes as final.
• Add uuid6() method to UuidFactoryInterface.

Deprecated

• Uuid::UUID_TYPE_IDENTIFIER is deprecated. Use Uuid::UUID_TYPE_DCE_SECURITY instead.
• Uuid::VALID_PATTERN is deprecated. Use Validator\GenericValidator::VALID_PATTERN instead.

Fixed

• Fix microsecond rounding error on 32-bit systems.

Added

• Add Uuid::fromDateTime() to create version 1 UUIDs from instances of \DateTimeInterface.
• Add Generator\NameGeneratorInterface to support alternate methods of generating bytes for version 3 and version 5 name-based UUID. By default, ramsey/uuid uses the Generator\DefaultNameGenerator, which uses the standard algorithm this library has used since the beginning. You may choose to use the new Generator\PeclUuidNameGenerator to make use of the new uuid_generate_md5() and uuid_generate_sha1() functions in ext-uuid version 1.1.0.

Changed

• Add fromDateTime() method to UuidFactoryInterface.
• Change UuidInterface::getHex() to return a Ramsey\Uuid\Type\Hexadecimal instance.
• Change UuidInterface::getInteger() to return a Ramsey\Uuid\Type\IntegerValue instance.

Fixed

• Round microseconds to six digits when getting DateTime from v1 UUIDs. This circumvents a needless exception for an otherwise valid time-based UUID.

Added

• Add Validator\ValidatorInterface and Validator\GenericValidator to allow flexibility in validating UUIDs/GUIDs.
  • Add ability to change the default validator used by Uuid through FeatureSet::setValidator().
  • Add getValidator() and setValidator() to UuidFactory.
• Add an internal InvalidArgumentException that descends from the built-in PHP \InvalidArgumentException. All places that used to throw \InvalidArgumentException now throw Ramsey\Uuid\Exception\InvalidArgumentException. This should not cause any BC breaks, however.
• Add an internal DateTimeException that descends from the built-in PHP \RuntimeException. Uuid::getDateTime() may throw this exception if \DateTimeImmutable throws an error or exception.
• Add RandomSourceException that descends from the built-in PHP \RuntimeException. DefaultTimeGenerator, RandomBytesGenerator, and RandomNodeProvider may throw this exception if random_bytes() or random_int() throw an error or exception.
• Add Fields\FieldsInterface and Rfc4122\FieldsInterface to define field layouts for UUID variants. The implementations Rfc4122\Fields, Guid\Fields, and Nonstandard\Fields store the 16-byte, binary string representation of the UUID internally, and these manage conversion of the binary string into the hexadecimal field values.
• Add Rfc4122\UuidInterface to specifically represent RFC 4122 variant UUIDs.
• Add classes to represent each version of RFC 4122 UUID. When generating new UUIDs or creating UUIDs from existing strings, bytes, or integers, if the UUID is an RFC 4122 variant, one of these instances will be returned:
  • Rfc4122\UuidV1
  • Rfc4122\UuidV2
  • Rfc4122\UuidV3
  • Rfc4122\UuidV4
  • Rfc4122\UuidV5
  • Rfc4122\NilUuid
• Add Rfc4122\UuidBuilder to build RFC 4122 variant UUIDs. This replaces the existing Builder\DefaultUuidBuilder, which is now deprecated.
• Add ability to generate version 2 (DCE Security) UUIDs, including the static method Uuid::uuid2(), which returns an Rfc4122\UuidV2 instance.
• Add classes to represent GUIDs and nonstandard (non-RFC 4122 variant) UUIDs:
  • Guid\Guid
  • Nonstandard\Uuid.
• Introduce a Builder\FallbackBuilder, used by FeatureSet to help decide whether to return a Uuid or Nonstandard\Uuid when decoding a UUID string or bytes.
• Introduce Type\Hexadecimal, Type\IntegerValue, and Type\Time for improved type-safety when dealing with arbitrary string values.
• Introduce Math\CalculatorInterface for representing calculators to perform arithmetic operations on integers.
• Depend on brick/math for the Math\BrickMathCalculator, which is the default calculator used by this library when math cannot be performed in native PHP due to integer size limitations. The calculator is configurable and may be changed, if desired.
• Add Converter\Number\GenericNumberConverter and Converter\Time\GenericTimeConverter which will use the calculator provided to convert numbers and time to values for UUIDs.
• The \DateTimeInterface instance returned by UuidInterface::getDateTime() (and now Rfc4122\UuidV1::getDateTime()) now includes microseconds, as specified by the version 1 UUID.

Changed

• Set minimum required PHP version to 7.2.
• Add __toString() method to UuidInterface.
• The UuidInterface::getDateTime() method now specifies \DateTimeInterface as the return value, rather than \DateTime; Uuid::getDateTime() now returns an instance of \DateTimeImmutable instead of \DateTime.
• Add getFields() method to UuidInterface.
• Add getValidator() method to UuidFactoryInterface.
• Add uuid2() method to UuidFactoryInterface.
• Add convertTime() method to Converter\TimeConverterInterface.
• Add getTime() method to Provider\TimeProviderInterface.
• Change Uuid::getFields() to return an instance of Fields\FieldsInterface. Previously, it returned an array of integer values (on 64-bit systems only).
• Change the first required constructor parameter for Uuid from array $fields to Rfc4122\FieldsInterface $fields.
• Introduce Converter\TimeConverterInterface $timeConverter as fourth required constructor parameter for Uuid and second required constructor parameter for Builder\DefaultUuidBuilder.
• Change UuidInterface::getInteger() to always return a string value instead of mixed. This is a string representation of a 128-bit integer. You may then use a math library of your choice (bcmath, gmp, etc.) to operate on the string integer.
• Change the second required parameter of Builder\UuidBuilderInterface::build() from array $fields to string $bytes. Rather than accepting an array of hexadecimal strings as UUID fields, the build() method now expects a byte string.
• Generator\DefaultTimeGenerator no longer adds the variant and version bits to the bytes it returns. These must be applied to the bytes afterwards.
• Converter/TimeConverterInterface::calculateTime() now returns Type\Hexadecimal instead of array. The value is the full UUID timestamp value (count of 100-nanosecond intervals since the Gregorian calendar epoch) in hexadecimal format.
• Change methods in converter interfaces to accept and return string values instead of mixed; this simplifies the interface and makes it consistent:
  • NumberConverterInterface::fromHex(string $hex): string
  • NumberConverterInterface::toHex(string $number): string
  • TimeConverterInterface::calculateTime(string $seconds, string $microseconds): array
• UnsupportedOperationException is now descended from \LogicException. Previously, it descended from \RuntimeException.
• When encoding to bytes or decoding from bytes, OrderedTimeCodec now checks whether the UUID is an RFC 4122 variant, version 1 UUID. If not, it will throw an exception—InvalidArgumentException when using OrderedTimeCodec::encodeBinary() and UnsupportedOperationException when using OrderedTimeCodec::decodeBytes().
• Out of the box, Uuid::fromString(), Uuid::fromBytes(), and Uuid::fromInteger() will now return either an Rfc4122\UuidInterface instance or an instance of Nonstandard\Uuid, depending on whether the input contains an RFC 4122 variant UUID with a valid version identifier. Both implement UuidInterface, so BC breaks should not occur if typehints use the interface.
• By default, the following static methods will now return the specific instance types. This should not cause any BC breaks if typehints target UuidInterface:
  • Uuid::uuid1 returns Rfc4122\UuidV1
  • Uuid::uuid3 returns Rfc4122\UuidV3
  • Uuid::uuid4 returns Rfc4122\UuidV4
  • Uuid::uuid5 returns Rfc4122\UuidV5

Deprecated

The following functionality is deprecated and will be removed in ramsey/uuid 5.0.0.

• The following methods from UuidInterface and Uuid are deprecated. Use their counterparts on the Rfc4122\FieldsInterface returned by Uuid::getFields().
  • getClockSeqHiAndReservedHex()
  • getClockSeqLowHex()
  • getClockSequenceHex()
  • getFieldsHex()
  • getNodeHex()
  • getTimeHiAndVersionHex()
  • getTimeLowHex()
  • getTimeMidHex()
  • getTimestampHex()
  • getVariant()
  • getVersion()
• The following methods from Uuid are deprecated. Use the Rfc4122\FieldsInterface instance returned by Uuid::getFields() to get the Type\Hexadecimal value for these fields, and then use the arbitrary-precision arithmetic library of your choice to convert them to string integers.
  • getClockSeqHiAndReserved()
  • getClockSeqLow()
  • getClockSequence()
  • getNode()
  • getTimeHiAndVersion()
  • getTimeLow()
  • getTimeMid()
  • getTimestamp()
• getDateTime() on UuidInterface and Uuid is deprecated. Use this method only on instances of Rfc4122\UuidV1.
• getUrn() on UuidInterface and Uuid is deprecated. It is available on Rfc4122\UuidInterface and classes that implement it.
• The following methods are deprecated and have no direct replacements. However, you may obtain the same information by calling UuidInterface::getHex() and splitting the return value in half.
  • UuidInterface::getLeastSignificantBitsHex()
  • UuidInterface::getMostSignificantBitsHex()
  • Uuid::getLeastSignificantBitsHex()
  • Uuid::getMostSignificantBitsHex()
  • Uuid::getLeastSignificantBits()
  • Uuid::getMostSignificantBits()
• UuidInterface::getNumberConverter() and Uuid::getNumberConverter() are deprecated. There is no alternative recommendation, so plan accordingly.
• Builder\DefaultUuidBuilder is deprecated; transition to Rfc4122\UuidBuilder.
• Converter\Number\BigNumberConverter is deprecated; transition to Converter\Number\GenericNumberConverter.
• Converter\Time\BigNumberTimeConverter is deprecated; transition to Converter\Time\GenericTimeConverter.
• Provider\TimeProviderInterface::currentTime() is deprecated; transition to the getTimestamp() method on the same interface.
• The classes for representing and generating degraded UUIDs are deprecated. These are no longer necessary; this library now behaves the same on 32-bit and 64-bit PHP.
  • Builder\DegradedUuidBuilder
  • Converter\Number\DegradedNumberConverter
  • Converter\Time\DegradedTimeConverter
  • DegradedUuid

Removed

• Remove the following bytes generators and recommend Generator\RandomBytesGenerator as a suitable replacement:
  • Generator\MtRandGenerator
  • Generator\OpenSslGenerator
  • Generator\SodiumRandomGenerator
• Remove Exception\UnsatisfiedDependencyException. This library no longer throws this exception.

Fixed

• Add #[ReturnTypeWillChange] to Uuid::jsonSerialize() method.

Fixed

• Switch back to ^8.0 in the PHP version requirement.

Fixed

• Indicate support for PHP 8.1, using ~8.1.0 to prevent installations on 8.2 until the library is ready.

Fixed

• Allow installation of paragonie/random_compat v9.99.100 (for PHP 8 compatibility).

Fixed

• For v1 UUIDs, round down for timestamps so that microseconds do not bump the timestamp to the next second.

  As an example, consider the case of timestamp 1 with 600000 microseconds (1.600000). This is the first second after midnight on January 1, 1970, UTC. Previous versions of this library had a bug that would round this to 2, so the rendered time was 1970-01-01 00:00:02. This was incorrect. Despite having 600000 microseconds, the time should not round up to the next second. Rather, the time should be 1970-01-01 00:00:01.600000. Since this version of ramsey/uuid does not support microseconds, the microseconds are dropped, and the time is 1970-01-01 00:00:01. No rounding should occur.

Fixed

• Check whether files returned by /sys/class/net/*/address are readable before attempting to read them. This avoids a PHP warning that was being emitted on hosts that do not grant permission to read these files.

Fixed

• Fix RandomNodeProvider behavior on 32-bit systems. The RandomNodeProvider was converting a 6-byte string to a decimal number, which is a 48-bit, unsigned integer. This caused problems on 32-bit systems and has now been resolved.

Added

• Add function API as convenience. The functions are available in the Ramsey\Uuid namespace.
  • v1(int|string|null $node = null, int|null $clockSeq = null): string
  • v3(string|UuidInterface $ns, string $name): string
  • v4(): string
  • v5(string|UuidInterface $ns, string $name): string

Changed

• Use paragonie/random-lib instead of ircmaxell/random-lib. This is a non-breaking change.
• Use a high-strength generator by default, when using RandomLibAdapter. This is a non-breaking change.

Deprecated

These will be removed in ramsey/uuid version 4.0.0:

• MtRandGenerator, OpenSslGenerator, and SodiumRandomGenerator are deprecated in favor of using the default RandomBytesGenerator.

Fixed

• Set ext-json as a required dependency in composer.json.
• Use PHP_OS instead of php_uname() when determining the system OS, for cases when php_uname() is disabled for security reasons.

Added

• Support discovery of MAC addresses on FreeBSD systems
• Use a polyfill to provide PHP ctype functions when running on systems where the ctype functions are not part of the PHP build
• Disallow a trailing newline character when validating UUIDs
• Annotate thrown exceptions for improved IDE hinting

Fixed

• Gracefully handle cases where glob() returns false when searching /sys/class/net/*/address files on Linux
• Fix off-by-one error in DefaultTimeGenerator

Security

• Switch to random_int() from mt_rand() for better random numbers

Fixed

• Check sysfs on Linux to determine the node identifier; this provides a reliable way to identify the node on Docker images, etc.

Fixed

• Set the multicast bit for random nodes, according to RFC 4122, §4.5

Security

• Use random_bytes() when generating random nodes

Added

• Add the following UUID version constants:
  • Uuid::UUID_TYPE_TIME
  • Uuid::UUID_TYPE_IDENTIFIER
  • Uuid::UUID_TYPE_HASH_MD5
  • Uuid::UUID_TYPE_RANDOM
  • Uuid::UUID_TYPE_HASH_SHA1

Fixed

• Optimize UUID string decoding by using str_pad() instead of sprintf()

Added

• Add InvalidUuidStringException, which is thrown when attempting to decode an invalid string UUID; this does not introduce any BC issues, since the new exception inherits from the previously used InvalidArgumentException

Fixed

• Improve memory usage when generating large quantities of UUIDs (use str_pad() and dechex() instead of sprintf())

Fixed

• Improve test coverage

Fixed

• Fix issue where the same UUIDs were not being treated as equal when using mixed cases

Added

• Add OrderedTimeCodec to store UUID in an optimized way for InnoDB

Fixed

• Fix invalid node generation in RandomNodeProvider
• Avoid multiple unnecessary system calls by caching failed attempt to retrieve system node

Fixed

• Fix test that violated a PHP CodeSniffer rule, breaking the build

Added

• Add TimestampFirstCombCodec and TimestampLastCombCodec codecs to provide the ability to generate [COMB sequential UUIDs] with the timestamp encoded as either the first 48 bits or the last 48 bits
• Improve logic of CombGenerator for COMB sequential UUIDs

Security

• Drop the use of OpenSSL as a fallback and use [paragonie/random_compat] to support RandomBytesGenerator in versions of PHP earlier than 7.0; this addresses and fixes the [collision issue]

Added

• Add SodiumRandomGenerator to allow use of the [PECL libsodium extension] as a random bytes generator when creating UUIDs
