GNU EMACS VERSIONING -*- org -*-

|
Emacs version numbers have the form
|
||
|
|
|
||
|
|
major.minor[.devel].build
|
||
|
|
|
||
|
|
"build" increments each time Emacs is built in the same location
|
||
|
|
(without cleaning) and isn't really part of the version.
|
||
|
|
|
||
|
|
bugfix releases increase "minor" by 1.
|
||
|
|
non-bugfix releases increase "major" by 1, and reset "minor" to 1.
|
||
|
|
(The division between bugfix and non-bugfix has not always been clear
|
||
|
|
historically.)
|
||
|
|
|
||
|
|
Unreleased (development) versions have an extra "devel" component.
|
||
|
|
This is a fairly meaningless number that may be unchanged for a long time.
|
||
|
|
It is normally 50.
|
||
|
|
When the release process starts, it changes to 90, 91, ...
|
||
|
|
When the actual release is made, this component is removed.
|
||
|
|
|
||
|
|
The development version for a new major release has "minor" = 0.
|
||
|
|
The development version for a new minor release has "minor" = that of
|
||
|
|
the previous release.
