Fix Released

Bug description:
Impact
------
New webkit2gtk releases usually include security fixes and are therefore handled similar to how new Firefox releases are handled. It would be helpful to get this built now for 25.10 before Final Freeze. Otherwise, it will just get updated later.
This is the first release in the stable 2.50.x series and includes
several other bug fixes also.
