There are fixes for at least twenty-six security issues in the latest version of Chrome, 49.0.2623.75.

The release announcement lists the most important security fixes, while making it clear that the full details may not be made available until the majority of users have had a chance to update.

The full change log for Chrome 49 seems to go on forever. I tried to find the end of it, but gave up after a few pages. At least it doesn’t try to load in one page, since that would probably crash most browsers. Presumably if Google had made any really interesting changes in Chrome 49, they would have been mentioned in the announcement.
