Clojure version history

There are two tables below: First the short table containing only the final releases, followed by the longer table containing alpha, beta, and RC (Release Candidate) releases.  This list is focused on versions with performance results included in the Clojure benchmarks graphs.  Some are intentionally left out because they are nearly identical to the preceding or following version.

The column giving the number of "non-trivial" commits to the source code since the previous version is estimated by looking through the git commit history, and trying to avoid counting commits that only update a README or change log file, and not counting commits with comments like "[maven-release-plugin] prepare release clojure <version>" and "[maven-release-plugin] prepare for next development iteration".  No other judgement has been made about the commits, e.g. some of the commits included in the counts below may be changes to doc strings only, and thus have little or no effect on the run-time performance of the benchmarks.

No versions before Clojure 1.2.0 are recorded here except final releases 1.0 and 1.1.0.  Feel free to contact me if you have details on those earlier versions you are interested in seeing added.
