We do not currently provide support or updates for any other versions except in cases of severe security issues.
On LTS's:
Forge's support for Minecraft versions will try to follow a predictable cycle, assuming Mojang also follows a predictable cycle. We will always actively target the latest Minecraft version as ever, however we will also support the most recent non-latest version as an "LTS" version.
An LTS version differs slightly from the latest version, in that any new features you may want to add to it, must target the latest version, only once it has been merged in, can it be backported. (The exception to this is if the feature is non-applicable to the latest version.) The Forge Team will also mostly be focusing on the latest.
This is so the community has time to stabilize a bit and gives modpack developers some time to create something special. But still have Forge running full steam ahead.
