Arduino IDE suggest new AVR Core for dev builds

[NicoHood]

I cloned the git master and rebuilt it myself. Now the IDE suggests me a new AVR core.
If you use this core, the HID library will not be available for example.

You have to manually delete the package in the .arduino15/appdata folder.

If you want to let someone test a patch and he clicks update and doesnt know this, this is a problem. Especially because there ARE problems with HID and Windows10 and the new hourly build fixes this.

Also the Firmata lib causes some warnings.

This is expected, if the avr core you're using is older than the latest. Ignore the notification if you're not interested in upgrading. Or port your patch to the latest avr core available

[NicoHood]

The suggested core was older, the HID library (pluggable HID) was missing.
I built the master branch myself, so it is impossible to be out of date.

[ffissore]

So you're saying you had core 1.6.8 and the IDE suggested using core 1.6.7?

[NicoHood]

The IDE says 1.6.7 is installed and wants to download 1.6.8
But 1.6.8 does not contain the HID library. The user in the linked issue above might have the same problem.

I dont know where this 1.6.8 comes from, but it is not up to date with the master (hourly build/custom build).

[ffissore]

Ah I see. So the IDE is behaving as expected. 1.6.8 has been released with IDE 1.6.5-r5, with genuino boards support. /cc @cmaglie
@NicoHood please update your copy of master and rebuild

[NicoHood]

And why is the HID library not included there (in the newer commit) if my older build includes HID already?

[cmaglie]

The release of IDE 1.6.5-r5 is a "service" release, it's not meant to provide new functionality except the support for those additional PIDs and drivers for Genuino boards (for this reason the core doesn't contains the HID change you mentioned).

BTW even if we "only" added some pid definitions in the file boards.txt, the presence of the boards manager forced us to make a new release of the AVR core (and to set its version to 1.6.8 because the IDE versions and cores versions are now independent from each other).

This lead to have an AVR core 1.6.8 (basically identical to AVR core 1.6.7), and your hourly build is saying that you have an ""upgrade"" available!

Hope this helps to understand what happened.
This problem should be fixed if you download again the hourly build (or update the git tree and rebuild the IDE).
