v1.6.2 (Bugfix release)

New features

Bugfixes

• #275 sensor fixes

• more graceful handling of wireless devices

Improvements

• Awesome fonts in the theme can now be referenced by name (using ${})
• Add generic mechanism for slow updates and use it for various modules (hopefully, this part didn't break anything)

Bugfixes

• Update stock widget only every hour

Small hotfix release (Do not fill the disk)

fixes #213: bumblebee-status always logged messages to stderr (even when -d was not specified), which end up in ~/.xsession-errors and consume a lot of diskspace very quickly.

This release completely disables logging, as long as -d is not specified.

Also, introduces two "special" log file names, stdout and stderr to log to stdout and stderr, respectively.

Theme support extension release

• Add support for pywal in themes: Add a "colors" instruction and then simply use names for your pywal colors (see the wal-powerline.json themes for examples)
• Themes can now be stored outside the repository structure (i.e. in ~/.config/bumblebee-status/themes/). Themes will be merged, so it is also possible to partially overwrite theme instructions by placing partial JSON files in this directory, with the same name as the main theme (for example, anything you write into ~/.config/bumblebee-status/themes/powerline.json will overwrite the default powerline theme settings).

New modules

• rotation by cacyss0807: Cycle through display orientations
• hipchat by fredj: Show number of unread hipchat messages
