SSI changes between 2.0.15 and 2.1?

[MrManager]

Is there a summary somewhere of the changes (if any) to the SSI.php integration in the new 2.1 release? I am using this quite heavily on my site so it would be good to know what I'd need to fix when I do the upgrade.

Also potentially useful: https://github.com/SimpleMachines/SMF2.1/compare/a18e888838460a816fdbc2703e7e05ce7f626c91..release-2.1#diff-cfc225eff5aeb11b2e42d1a705c3ae63

Technically, that shows the difference between SSI.php as it existed when the 2.1 repository was first created and as it exists now, so it won't reflect any changes made to SSI.php in the 2.0 branch after 2.1 was split off. That isn't exactly what you asked for, but it'll do more or less what you want.
