The Dev channel has been updated to 4.0.237.0 for all platforms (Windows, Mac, and Linux). The focus on this release has been feature polish, stability improvement, and extensions work.

Mac

• Significant bookmark bar improvements.

Linux

• [r29163, r29299] Audio playing improvements in video/audio tags. (Issues: 23974, 20945, 17703)
• [r29261] Fix international keyboard handling (alt-gr, ctrl+f). (Issues: 10846, 2215, 21471)
• [r29657] ~ now works in the Omnibox to expand to home directories. (Issue: 18200)
• [r29857] Fix conflicts between accelerator keys and HTML DOM accesskeys. (Issue: 21624)
• [r29903] Inactive pinned tabs on linux throb when the title changes. (Issue: 25308)
• Text drawn over rounded corners (including buttons) is no longer blurry. This affected a variety of sites, including Google Calendar and Google Reader.
• As an experiment, we've changed the way clicking in the omnibox works. Leave a comment on the bug if it bothers you.

Extensions

• Lots of work to polish and stabilize the browser and page action APIs:
• [r29556] Add badge text color API. Also change color APIs from ARGB to RGBA (breaking change, sorry!) (Issues: 24635, 24644, 25215)
  
• [r29152, r29785] Browser actions (buttons, popups) are now implemented. (Issue: 23882, 23897)
  
• [r29997] Add support for tab-specific state to browser actions. Also, fix the bug where only the first call to setIcon() works. (Issues: 24669,24472)
  
• [r30346] Constrain browser action popups to a min/max size. Also fix some glitches in popup sizing. (Issue 25214)
  
• [r30499] Use a better signature for the new page actions API (chrome.pageAction.* instead of chrome.pageActions.*). This is technically a breaking change, but hopefully not too many people had gotten around to using the new API yet. (Issue 25833)
  
• [r29665] Remove toolstrips on linux. They were causing lots of crashes and are going away soon anyway. (Issue 25106)
  
• [r29911] Add chrome.extension.sendRequest() -- a simpler way to do content script messaging. (Issue 23865)
  
• [r30341] Add new event chrome.tabs.onStatusChange. This makes the common case of wanting to know when tabs load much easier. (Issue 21729)
  
• Other miscellaneous cleanup:
• [r29498] Correctly handle reloading in the task manager (Issue 18693)

• [r29555] Fix bug where content scripts did not always apply to first page load (Issue 11547)
• [r29714, r29922, r29935, r30219] Various cleanup for the extension management page (Issues 12119, 25509, 25471)
• [r30091] Improve install UI on mac (Issue 19654)
• [r30312] Filter out hidden files when loading and packing extensions (Issue 23004)
• [r30326] Copy chrome.extension.getTabContentses() to chrome.extension.getExtensionTabs(). Nobody liked the old name. (Issue 21433)
• [r30384] Use the puzzle piece as the default extension icon. (Issue 25906)
• [r30481] Hide the theme install bubble a little earlier. It was overlapping with the install dialog on linux. (Issue 26130)

Known Issues:

• [r26861] - Autocomplete/ select box values are not being correctly populated in Linux. As a work around you can use the up/down arrow keys to view the current selection.
• [r26600] - Task bar icon in Windows does not update/ display correctly.
