Revisions Versions revisions releases
Each version of a file has a unique revision number. Revision numbers look like `1.1
',
`1.2
', `1.3.2.2
' or even `1.3.2.2.4.5
'.
A revision number always has an even number of
period-separated decimal integers. By default revision
1.1 is the first revision of a file. Each successive
revision is given a new number by increasing the
rightmost number by one. The following figure displays
a few revisions, with newer revisions to the right.
+-----+ +-----+ +-----+ +-----+ +-----+ ! 1.1 !----! 1.2 !----! 1.3 !----! 1.4 !----! 1.5 ! +-----+ +-----+ +-----+ +-----+ +-----+
It is also possible to end up with numbers containing
more than one period, for example `1.3.2.2
'. Such
revisions represent revisions on branches
(see Branching and merging); such revision numbers
are explained in detail in Branches and revisions.
