Drop or keep 1.7 support?

[satoshinm]

Hi, hope this is ok to post here, if anyone else is interested in 1.7.x support I am backporting it to the latest version of Cuberite. The existing code that was removed can be mostly added back without too many difficulties, but there were some new and changed virtual methods I had to modify to get it to build. Then there were game incompatibilities to resolve: not sending the offhand item (45th slot in player inventory) to not crash the 1.7 client, and sending named sound effects with the old names (like "random.chestopen" instead of block.chest.open) instead. However it mostly seems to work after resolving these issues, and I have not seen the block placement issue (#2026), though new items not present in may still be a problem (#2275).

I understand the community voted to remove 1.7, but if anyone wants my version it can be found on my GitHub (same username) under the "restore17" branch, and I welcome feedback (bug reports or fixes) on that repository (issues are enabled).
