An update to the Portal 2 has been released. The update will be applied automatically when your Steam client is restarted. The major changes include:- 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.
