[tor-commits] [tor-browser/tor-browser-78.14.0esr-11.0-1] Bug 16940: After update, load local change notes.
commit 24584d3c52d21f9d9975d39cfede4b1b177e52bb
Author: Kathy Brade <brade@xxxxxxxxxxxxxxxxx>
Date: Wed Nov 25 11:36:20 2015 -0500
Bug 16940: After update, load local change notes.
Add an about:tbupdate page that displays the first section from
TorBrowser/Docs/ChangeLog.txt and includes a link to the remote
post-update page (typically our blog entry for the release).
Always load about:tbupdate in a content process, but implement the
code that reads the file system (changelog) in the chrome process
for compatibility with future sandboxing efforts.
Also fix bug 29440. Now about:tbupdate is styled as a fairly simple
changelog page that is designed to be displayed via a link that is on
about:tor.
