Based by language in Google Help, it appears that Chrome version 49.0.2623.108 m is the latest and final version that will be released for XP and Vista.
The previous language was "This computer will soon stop receiving Google Chrome updates because Windows XP and Windows Vista will no longer be supported."
The new language is "This computer will no longer receive Google Chrome updates because Windows XP and Windows Vista are no longer supported."
Once Chrome 50 rolls along, it is my intention to re-implement the XP and Vista code that is being stripped from the future versions.
While I strongly recommend that users move to Firefox, I will see if it is possible to reinstate the XP compatibility that I believe is being artificially stripped from Chrome. In other words, with the XP code I'm certain Win32 Chrome will continue to run without issues.
If you wish to download the final 49.0.2623.108 m full installer, you can get it from my FTP here: http://sdfox7.com/xp/sp3/EOL/chrome/ChromeStandaloneSetup.exe (digitally signed March 22, 2016)
