13: History of Gri Versions

Gri, like many modern software projects, has two ``streams'' of development running side by side. One is called ``stable,'' the other ``unstable.'' Most users should use the stable stream, which has been well tested. (The unstable version is for users who wish to try out new features that are under development.)

Stable versions always have an even number as the middle number in their version designation, e.g. `2.6.0', while unstable versions always have an odd number there, e.g. `2.7.0'. This middle number indicates a sort of family of related releases. Within a stable stream, all versions sharing a given middle number have the same features; new releases are made only to fix bugs. Thus, version `2.6.1' fixed bugs in version `2.6.0'.

To learn more about the bugs, and their resolution, visit the bugs page at

and adjust the "status" menu to read "closed".
