Please test your packages on stretch with webkit2gtk 2.16.3-2 which I have requested to be unblocked for stretch this week. The current version in stretch is 2.14.7-1. 2.16.3 is a new major release but it is also a security release and the webkit2gtk developers try to be careful to avoid regressions in new release and fix regressions quickly once informed of them.
A list of affected packages can be found at https://paste.debian.net/961084/ I suggest briefly enabling unstable in your sources.list and running commands like this: sudo apt update sudo apt install gir1.2-webkit2-4.0 and then disable unstable again. If you find any problems as a result of this update, please reply to Debian bug #863915 I do apologize for the lateness of this request, but it seems like it would be better to do this major version bump now rather than for 9.1. My intention is to try to package further webkit2gtk updates for Debian 9 "stretch" until buster is released as the new stable release. webkit2gtk has new major versions every March and September (like GNOME) with periodic security and bugfix releases in between. These new versions are being packaged in Ubuntu LTS and most other major Linux distributions. For more details, see bug #863915. Thank you, Jeremy Bicha
