tr46

Updates to Unicode 16.0.0.

Updates to follow TR 46 revision 33 (spec changelog). This did not include any public API changes but did include some logic changes.

Raises the Node.js minimum version to v18.x.

Updates to Unicode 15.1.0.

Updates to follow TR 46 revision 31 (spec changelog):

• Changes processingOption from being a string-valued option to a boolean transitionalProcessing option.
• Adds the ignoreInvalidPunycode option.
• A few other algorithm changes.

This version fixes empty label handling, e.g. in inputs such as xn--4-0bd15808a. which consist of one label "xn--4-0bd15808a" followed by another label "".

Published specifications are ambiguous on this; TR 46 calls RFC 5893's "The Bidi Rule", which assumes all labels are nonempty. Previously, tr46 operations would fail on such inputs. Now, they behave like browsers do, and pass through the empty labels. This feedback has been given to the TR 46 authors as part of https://github.com/whatwg/url/issues/744.

This properly updates several Unicode tables to Unicode 15.0.0. (It turns out the upgrades in previous releases were incomplete, and those tables, unlike other parts of the package, were stuck on Unicode 12.1.0!)

Raise Node.js minimum version to v14.x.

This version brings support for Unicode 15.0.0.

This version ensures we're using the actual punycode npm package, instead of Node.js's built-in version. The latter is deprecated and hasn't seen the latest bug fixes.

Raise Node.js minimum version to v12.x.

This version brings support for Unicode 14.0.0.

This version brings support for Unicode 13.0.0.

Compared to version 2.0.0, the package bundle size is now much smaller thanks to work by @kraynel. (#24)

This version was published immediately after 2.0.1 to fix a packaging issue.

This release is buggy; use version 2.0.2 instead.

Breaking changes:

• Raise Node.js minimum version to v8.x. We are now also advertising the supported Node.js version in the engines field in package.json. (#16, #21, @breeeew)

Other fixes:

• Make transitional processing available for toUnicode, as required by UTS <span>#</span>46 11.0.0 (rev 21).
• Update code point tables to Unicode 12.1.0.

In this release, a few small bugs have been fixed around the area of host validation, when useSTD3ASCIIRules or checkBidi options are used. Testing infrastructure has been fixed to ignore buggy cases in the official test suite.

This version is considered the first stable release of tr46. Among the changes introduced are full support for all options in UTS 46, up to its 10.0.0 version. A stable API has been created.
