Latest release

The latest release of the plugin is version 0.0.9 (Redmine 0.9.2 compatibility release).


The Redmine Arch Decisions plugin can be used to track technical decisions (architecture, or "arch" decisions) made as part of a project. It encourages collaboration by the whole team, helps make assumptions and rationale explicit, and helps keep track of which options are being or have been considered. For a more in-depth discussion of the benefits and features of this plugin, see:


This plugin was originally made for Redmine 0.8.4, and up through release 0.0.8 it is best used with that version.
As of release 0.0.9, the "master" branch is certified for use with Redmine 0.9.2 (and is probably not compatible with 0.8.x).
A separate branch ("redmine-0.8.4") has been created for those that wish to use that version. No promises are being made as to whether or not
new functionality will be merged to this branch, although bug fixes will for the time being be supported.
