Portal 2

 * Added more descriptive error messages to common publishing failures.
 * Optimizations and rendering improvements for the Puzzle Maker.
 * Fixed compile error from fizzlers in certain orientations.
 * Fixed stacked goo creating kill triggers that spanned between the two levels of goo.
 * Fixed connection symbols potentially leaking outside the map, causing maps to fail compiling.
 * Fixed some lightboards not showing their map titles and tags properly
 * Fixed compiler error when trying to compile certain very large maps.
 * Localization fixes and additions.
 * Autosaves made while playing workshop/puzzlemaker maps no longer conflict with singleplayer saves.
 * Fixed glass not having collision before being moved after being dropped in.
 * Fixed paint dropper arc becoming weird while extruding.
 * Fixed going through portals on angled platforms in goo killing the player.
 * A loading screen will always show up when playing puzzlemaker/workshop maps and dying or restarting the maps.
 * Using puzzlemaker_export to export a custom vmf will make the player start in the elevators and not spawn the triggers that restart the map when walking in the exit hallway
 * Better progress indication for compiling puzzles.
 * Paint is valid on goo and buttons now.
 * Fixed a crash on completing the preview puzzle.
 * Fixed the first item in the map list not always showing valid information.
 * Fix a variety of bugs (some Mac-specific, mostly platform-independent) which made the texture filter setting in the Advanced Video Options act incorrectly.
 * Fixed bug with light strips and fizzlers sometimes changing the portalability of the surface they were on during export.
 * Fizzlers are now properly sorted when a portal shot hits a fizzler. This makes the correct fizzler light up when there are multiple fizzlers along the portal shot.
 * Better item handle interactions.
 * The catapult target is now copyable. Copying the target will drop a catapult on the spot and attach a target to your cursor.
 * Fixed the box dropper and paint dropper disappearing if you did Undo past their creation, then Redo back through it.
 * Fixed hitting "Undo" while dragging causing weird behaviors.
 * "Bendy" player model appears in all community map chambers now
 * Right mouse button clicking on a solid volume selection boundary surface no longer clears selection.
 * Bound 'view reset' to H as well as Home, for Mac users without a Home key
 * Removed bad keyvalues from elevator_exit instance
 * Fixed a crash due to deleted items not removing their collision entries
 * Fixed glass and rail platforms computing the wrong extents just after being undeleted.

Undocumented changes

 * Updated the splash-screen video shown when launching the game.
