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. This makes the correct fizzler light up when there are multiple fizzlers along the portal shot.
