2.6.9

Safe mode can be switched off on Linux

It could not before. Pressing the switch answered dota.signatures not found and stopped there,
which meant no mod could be loaded by the game at all on Linux.

The file it was looking for does not exist there. On Windows the client keeps a list of hashes in
bin/win64/dota.signatures and checks the files it loads against it, so this app has to write its
own line into that list. Valve's Linux build ships bin/linuxsteamrt64/ with the client, forty
shared libraries and no list at all, and the app treated that as a broken installation rather than
as a different one.

Nothing about it needs signing on Linux, so the patch is simply written and that is the whole job.
The switch also stops showing a warning dot for a list that was never there, and the app stops
re-applying a patch it thought had failed.

Reported with a photograph of the folder, which is what made it obvious.

Updates have a second source on Linux too

They were supposed to since 2.6.5, and for Linux they never did: the mirror was filled before the
Linux build existed, so it carried the Windows files and nothing else. Four releases went out that
way. Both Linux files are on it now, and a release that leaves any of the six behind fails loudly
instead of quietly.
