What's new in IntelHex 2.2 release.

Bugfixes

• Better compatibility with Python 3. (Alexander Belchenko)
• Script hexinfo.py: Python 3 compatibility for processing start address dict keys. (patch from GitHub user mentaal)
• Unit tests: Fixed xrange overflow test for Python 2.7 on 64-bit platforms. Use sys.maxint to ensure we trigger an exception. (Masayuki Takeda)

API changes

• IntelHex.write_hex_file method: added support for new parameter: eolstyle = native | CRLF. (Alexander Belchenko)
• IntelHex.write_hex_file() method gets new optional parameter byte_count to specify how many bytes should be written to each data record in output file. Default value is 16. (patch from GitHub user erki1993)

New features

• Added get_memory_size() method: approx memory footprint of IntelHex object plus data. (Alexander Belchenko)

What's new in IntelHex 2.1 release.

Bugfixes

• Better Python 3 compatibility when hex2bin.py and bin2hex.py scripts are trying to read/write binary data from stdin or to stdout. (GitHub issue https://github.com/bialix/intelhex/issues/4)

New features

• API changes: added IntelHex.segments() method that returns a list of ordered tuple objects, representing contiguous occupied data addresses. (Andrew Fernandes)
• New command-line script hexinfo.py to print summary about hex files contents (file name, start address, address ranges covered by the data) in YAML format. (Andrew Fernandes)
• API changes: IntelHex.dump() method gets new optional parameters: width, withpadding to control generation of output text. (patch from GitHub user durexyl)
• Script hex2dump.py gets new option --width to support corresponding parameter in IntelHex.dump() method.

Misc

• The main activity of the IntelHex project slowly drifting towards GitHub - the main social network for OSS developers. I'd really like to get some help from additional maintainer though.

Major improvements in IntelHex 2.0

• The same codebase can be run on both Python 2 (2.4-2.7) and Python 3 (3.2+). No need to use 2to3.

Bugfixes

• Python 3 compatibility: tobinstr should return bytes not unicode string (Launchpad Bug #1212698).
• Python 2: better support for long int addresses (over 2GB) (Launchpad Bug #1408934)

Internals

• compat.py: provide more helper functions and aliases to reduce changes required to convert python 2 compatible sources to python 3. The code becomes quite ugly, but such compatibility has its price.

• API changes: Functions tobinarray/tobinstr/tobinfile: pad parameter is deprecated and will be removed in future releases. Use IntelHex.padding attribute instead, and don't pass pad as None explicitly please. If you need to use size parameter, then use syntax like that: ih.tobinarray(start=xxx, size=yyy)

• API changes: Functions tobinarray/tobinstr/tobinfile: default value of pad is None now (was 0xFF) to allow using value of IntelHex.padding if no explicit pad specified.

• Fixed bug: wrong getopt error handling in some scripts. (Thanks to Andy Mozhevilov for bug report)

• PEP-8 style improvements. (Thanks to Stefan Schmitt)

• IntelHex16bit.tobinarray method returns array of unsigned short (words) values. (Feature request from Stefan Schmitt)

• Improved Python 3 compatibility (don't use old file() function). (Thanks to Luis Panadero Guardeño for bug report)
