FO is consistently one of the first packs to upgrade to new Minecraft versions, thanks to its efficient versioning model.

Mods' updates: Fabric (which usually updates very quickly), mods...
New additions or removals of mods, which need testing
The time FO's author has to work on updates
Generally, the development version of FO, which may not include all mods of a stable release, is released as soon as possible, often every week or two. Once a release is published, important updates to mods are usually quickly available.

X
Major versions
Y
Minor versions
Minecraft patches or changes to FO
Z
Patches
Non-breaking changes, no mod changes
The suffix is a term that approximately corresponds to the stages of Minecraft's development:

alpha
-alpha
pre-release
beta

release
stable
none
