The release contains mostly bug fixes for 0.3.154.0, but it also introduces a new behavior for downloading files that could be executable content:

* r3285 Changes the download behavior for files that could execute code (exe, dll, bat, etc.). These files are now downloaded to unconfirmed_*.download files. In the browser, you're asked if you want to accept the download. Only after you click Save is the unconfirmed_*.download file converted to the real file name. Unconfirmed downloads are deleted when Google Chrome exits.


Other Notable Changes
User Interface

* r3177, r3207 Enables sorting columns in the password manager, the list of URLs to load at startup, and the Google Chrome task manager. (Issue 2949, 95)
* r3180 Adds a command line switch to start the browser in incognito mode. Thanks to Yarin.Kaul@gmail.com for the contribution. (Issue 1790, 2012)
* r3189 Fixes the new bookmark bubble so that pressing enter with focus on the Edit button actually opens the editor. Thanks to developer0420@gmail.com for the fix. (Issue 2863)
* r3209 Changes the text in the About dialog to link to credits for other open source software used in Google Chrome and to the Terms of Service.
* r3264 Adds support for extended validation (EV) certificates issued ssued by Comodo using the AddTrust root. (Issue 2170)

Plugins

* r3211 Fixes a problem with videos stopping after 1 second (Issue 115)
* r3272 Allows plugins to post forms (for example, Adobe Reader forms). (Issue 629)
* r3276 Adds better support for Windows Media player, specifically improving detection for that plugin at bloomberg.com. (Issue 2846)
* r3327 Runs plugins at a normal priority so that they do not cause the browser to become unresponsive.

JavaScript/Web API

* r3198 Optimizes the content-type detector ('MIME sniffer') to do fewer, more reliable checks based on data collected during the Google Chrome Beta.
* r3231 Fixes a problem with page content disappearing behind plugin windows. For example, when you type a search on a page playing a YouTube video, the search suggestions stay visible instead of going behind the video window. (Issue 1788)
* r3269 Change the minimum timer resolution for setTimeout() to 4 milliseconds (up from 1ms). At 1ms, some pages would spin in tight loops and consume 100% of CPU.

Crashes in 154.0

* r3172 Fixes a crash when using the spell check Add to dictionary... fucntion. (Issue 3039)
* r3278 Fixes a browser crash on tablet PCs running Microsoft Windows Vista.
