We would also like to thank Atte Kettunen of OUSPG, Christian Holler, cloudfuzzer and Khalil Zhani for working with us during the development cycle to prevent security bugs from ever reaching the stable channel. $35000 in additional rewards were issued.

As usual, our ongoing internal security work was responsible for a wide range of fixes
  • [449894] CVE-2015-1205: Various fixes from internal audits, fuzzing and other initiatives.
  • Multiple vulnerabilities in V8 fixed at the tip of the 3.30 branch (currently 3.30.33.15).
Many of the above bugs were detected using AddressSanitizer or MemorySanitizer.

Also why is adobe's flash player version now 16.287?

Adobe Flash versions can be different across the various platforms. This is a different build than the Active-X or Plugin version.

After two months of waiting for the a stable update for version 40.

I STILL have problems with the bug that I've had since Thanksgiving. Where whenever you click on a link, then hover any other link. The white loading bar on the bottom left will not go away unless I hover outside of the browser, such as going to Chrome settings.

I expected this annoying little bugs to have been taken care of aeons ago.

My Chrome is fully up to date but every time I launch Google Chrome all my desktop icons refresh themselves. It has been happening for a short while before this new latest update. I have found that lots of people seem to have the same issue.
When is this going to be permanently fixed ????
I am using Windows7 sp1 (64 bit)
Desktop icons DON't not refresh themselves when I launch IE 11.

@Michaela: now that you mention it... Can confirm; same here. I didn't notice it that much but subconsciously it must've registered. I checked it explicitly and, indeed, when I close Chrome and launch a new instance: BOOM. Refresh!

Launching an instances when Chrome is already running: no problem (not even with Inprivate windows).

Hello Google team and people, I don´t know if it is mistake on your side, but do you have lags on YouTube now? I have terrible lags when I´m watching YouTube videos, I donť have that lags before version 40. I don´t know what is it, but can Google please fix it. It is terrible. Thank you for your understand, and I wish lot of successes in developing Google Chrome. Bye.

With this update, the click to play (plug-ins) has now changed to right click and select run this plug-in. Is this a mistake or intentional. This breaks several video players for me.

Very unstable! Version 40.0.2214.91 (64-bit) often crashes on OS X 10.7.5.

Hello Google, in this version I have problems when I leaf through picture galleries. The images are displayed delayed! When I click the mouse, it sure takes 4 seconds and the correct image is then displayed. Here's an example: http://www.20min.ch/schweiz/zuerich/story/Warum-durfte-Ruefer-nicht-weitermoderieren--13994764
Thanks for the correction.

The 40.0.2214.91 (64-bit) version is having issues rendering google fonts chars like: &rsaquo, &ndash, &mdash, adding strange symbols, the meta charset is set as : charset="UTF-8".

This was working perfect on the previous version, it looks fine in other browsers though.

any workaround this issue?
pd: I'm using : http://fonts.googleapis.com/css?family=Ubuntu:100,200,300,400 stylesheet.
