Notes:

• Removeddownload_build
  • Support for bisection using downloaded builds viaautobisect project will be added later
  • In the meantime, the existing support got removed as tinderbox builds are no longer produced by official builds
• Windows ICU library versions bumped

Fixes

• Entire repository standardised to use double quotes
• Continued work towards Python 3 support, Python 3.5 is now the target
  • More fixes for unicode/str confusion when interacting with other libraries, e.g. Lithium
• Standardised name toautobisectjs since there is now the separateautobisect project
• Started using more PyPI libraries
  • e.g.whichcraft instead of in-house functions without tests
• shell_flags got rewritten

• Linux builds now require GCC 6 (official build requirement)

Notes

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

Features:

• Basic pytest infrastructure added! - largely testscompile_shell for now
• Addcodecov.io support - Now with code coverage!
• evalInCooperativeThread andoomTest are now ignored when running differential testing.

Bugfixes:

• Backport .gitignore changes

0.1.1 primarily got released for Windows. Due to#139, Windows machines stayed on the legacy 0.1.x branch, whereas other OS'es moved on to the newer releases. This point release is needed to unbreak jsfunfuzz due to#148.

Bugfixes:

• Fix Xcode 9 builds on macOS

• First release with proper Python package folder layout structure
  • Assuming repository was cloned to~/funfuzz, can be installed via pip:pip install --upgrade ~/funfuzz
