Release History

Reverse chronological list of Octave releases.

All recent released versions going back to version 3.4.0 are tagged in the hg archive with a tag of the form release-MAJOR-MINOR-PATCH. So version 5.1.0 is tagged with "release-5-1-0". However, note that trying to build from an old tarball release isn't exactly the same thing as updating the hg archive to the corresponding hd id and trying to build from that. There are a number of generated files that are included in the tarball releases that are not stored in the hg archive. For old releases, using current tools to generate those files will likely result in some differences, unless you have installed the same old versions of tools like autoconf, bison, flex, gperf, etc. that were used to generate the old tarball release.

Before Version 1.0, there were frequent public releases beginning with 0.60. Why there were sometimes minor point releases like 0.71.[1-10], instead of just moving on to 0.72, is a mystery now.
