» Chromium 4.0.224.3 (29991), released on 23rd October 2009 allows the user to add links by drag n’ drop into the Bookmarks Bar area.
 

» Chromium 4.0.260.0 (33362), released on 30th November 2009 at 15:26, enables bookmark syncing by default without starting the browser from the Terminal with the --enable-sync flag.

 

» On the 8th December 2009 Google released the first Chrome Beta for the Macintosh, bearing version number 4.0.249.30. This version has no bookmark sync (even using the flag) and support for extensions was yanked out just as Google was launching its Chrome Extensions archive.

 

» On the 9th December 2009 with version 4.0.268.0 (34180) the Mac finally gains the Task Manager. It is available only using the Page Menu button (and then under “Developer” menu) but not yet from “View” where it is still greyed out. The feature was made available in both places with version 4.0.297.0 (36090) of Chromium, released on the 12th of January 2010.

 

» Chromiumversion 4.0.291.0 (35546) released on the 5th of January 2010 (at 12:40, to be exact) brings an implementation of the Bookmark Manager to the Macintosh platform. It gives Apple users the option to edit and manage their bookmarks, although only the ones in the Bookmarks Bar.


 

» On January 6, 2010, with version 4.0.288.1 of the developer channel of Chrome enables Extensions, Bookmark sync (nearly two months after Chromium), the Task Manager and the ‘Pin Tab’ contextual menu.

 

» The following week the Developer channell of Chrome jumped to version 4.0.295.0 and added the Cookie Manager and a rudimentary version of the Bookmark Manager but disabled the Task Manager (echoing previous changes in Chromium).
Also: exclusive to the Mac is some degree of support for gestures: performing a Cmd+three finger swipe now opens previous/next page in a new tab.

 

» Since version 4.0.300.0 (36432) from 15th January 2010, Chromium sports a more functional Bookmark Manager, more or less on par with the one on Windows and Linux and finally allowing users, among other things, to move bookmarks and to manage subfolders.


 

» With version 4.0.303.0 (36586) of Chromium, released on the 19th of January 2010, the Bookmark Manager’s ui becomes more Mac-like. The Bookmark Manager also includes other additions like the edit-on-click feature which debuted some hours earlier in build 36571.


 

» A giant step forward for Chrome was made on the 11th of February 2010, when Google made available a new beta for Macintosh. Version 5.0.307.7 added a lot of features missing from the original december release: Extensions (finally!), Bookmark sync, the Bookmark manager, the Cookie manager and the Task manager, making what is the most stable and official channel of Chrome for Apple users almost catch up with the feature list available on Windows.

» One of the last missing features, the Full Screen view, arrives on the Macintosh on the 16th of February 2010 with the 5.0.330.0 (39154) build of Chromium.
