I was a bit sad that the changelog was so small. Then I realized that maybe core features were stable and that's it, what was needed wasn't big beside spec and a few other things.
A lot of the year's effort went into things outside core - 2 releases of spec, 2 releases of core.specs, many releases of tools.deps.alpha / clj, tools.gitlibs, new release of REBL, etc. Lots of small fixes and enhancements in core too.
