XOWA currently releases a minor version every week, and a major version every month. The minor versions are for new changes while the major versions are generally for fixes.
Both versions should be considered stable. Note that XOWA has over 4,000 automated unit tests, and more are added in each release. However, for those who prefer a more conservative update, the monthly major version may be more suitable. Additional caution is taken to minimize the number of changes in the monthly version.
The minor version is released every Monday morning between 3 AM and 8 AM UTC.
The major version is released the first Monday morning of every month between 3 AM and 8 AM UTC.
