I need to correct myself here for unclear notation or off-by-one errors,
the flow is of course as follows:
trunk
x.y-1.51
|
|
|
release branchpoint
| \
x.y.51 x.y-1.90
| prerelease
| |
| |
v x.y-1.91
. prerelease
. |
. |
|
x.y-1.92
prerelease
.
.
.
x.y.0
base release
|
|
|
x.y.1
maintenance release
|
|
|
x.y.2
maintenance release
|
v
.
.
.
The revision number is sometimes bumped up on trunk as well, to 52, 53,
etc., though the criteria are not completely clear to me; perhaps to make
a trunk snapshot "release".
And last but not least for non-release builds the snapshot date is
automatically appended to the version number reported, as seen above.
