0.1.2

Bugfixes:

• .gitignore was backported from master
• Fixate several python linter/test package versions on Travis/AppVeyor
• Fix wrong-import-order pylint error messages
• Python 3 was never properly supported on the 0.1 legacy branch, so stop running the linters using it

This is the last point release on 0.1.x and marks the end-of-life of the 0.1 legacy branch.

0.4.2

Bugfixes:

• Fix #185 - Commandline argument -t "js" in bot.py is not recognized. But it is mentioned in the readme.md.
• Disable tests involving compile_shell on Python 2.7 mode unless Python 3.5+ is installed due to a mozilla-central requirement.
• This temporarily lowers code coverage numbers reported to Codecov via Travis, until Python 3.5+ support is finished.
• Integrated the isort Python checker into flake8 linting process
• More automation / documentation / linting fixes

Notes:

• Windows is still on the 0.1.x legacy branch, until Python 3.5+ support is completed

0.4.1

Bugfixes:

• Fixed crashes in grabCrashLog by dealing with str/unicode types better
• Made repos_update not update funfuzz anymore, since pip 10 no longer comes with a main method and we should not rely on the internals of pip
• Simplified boto import code
• Inlined platform detection code instead of relying on subprocesses
• Tweaked Travis / AppVeyor CI configurations

Notes:

• Windows is still on the 0.1.x legacy branch, until Python 3.5+ support is completed
