1.2.17rc2 (release candidate)

Improvements

• Improved the serial.log logging handler to roll over serial log on new connections to the printer instead of continuously appending to the same file. Please note that serial.log is a debugging tool only and should not be left enabled unless you are trying to troubleshoot something in your printer communication.
• Split JS/CSS/LESS asset bundles according into asset bundles for core + bundled plugins ("packed_core.{js|css|less}") and third party plugins ("packed_plugins.{js|css|less}"). That will allow the core UI to still function properly even if an installed third party plugin produces invalid JS and therefore causes a parser error for the whole plugin JS file. See #1544 for an example of such a situation.

Bug fixes

• Fixed a bug causing the update of OctoPrint to not work under certain circumstances: If 1.2.16 was installed and the settings were never saved via the "Settings" dialog's "Save", the update of OctoPrint would fail due to a KeyError in the updater. Reason is a renamed property, properly switched to when saving the settings.
• Fixed the logging subsystem to properly clean up after itself.
