Well, actually the Typo3 7 LTS versions were available for a couple of months through my Github repositories of cwmobileredirect and cwenvbanner already, however I never found the time to upload them to TER. Finally I found some time to upload it, so here you go:
cwmobileredirect on TER
cwenvbanner on TER
The new versions do not include any new features, I did some cleanup though, so Typo3 4.x is no longer supported. Please just stick with the old versions of the extensions in case you are still using one of these ancient Typo3 installations.
Besides Typo3 7 compatibility and cleanup I spend some time on making them work with a Composer based Typo3 installation (the outcome can be found on Github as well) and Travis CI. Since I only work on these extensions occasionally, this will surely help me in with the Typo3 8 LTS versions (which I hope to get done a bit earlier this time :-)).
