OpenRTE's version numbers are the union of several different values:
major, minor, release, and an optional quantifier.
- Major: The major number is the first integer in
the version string (e.g., v1.2.3). Changes in the major number
typically indicate a significant change in the code base and/or
end-user functionality. The major number is always included
in the version number.
- Minor: The minor number is the second integer in
the version string (e.g., v1.2.3). Changes in the minor number
typically indicate a incremental change in the code base and/or
end-user functionality. The minor number is always included
in the version number.
- Release: The release number is the third integer
in the version string (e.g., v1.2.3). Changes in the release number
typically indicate a bug fix in the code base and/or end-user
functionality. If the release number is 0, it is omitted from the
version number (e.g., v1.2 has a release number of 0).
- Quantifier: OpenRTE version numbers sometimes
have an arbitrary string affixed to the end of the version number.
Common strings include:
- aX: Indicates an alpha release. X is an integer
indicating the number of the alpha release (e.g., v1.2.3a5 indicates the 5th alpha release
of version 1.2.3).
- bX: Indicates a beta release. X is an integer
indicating the number of the beta release (e.g., v1.2.3b3 indicates the 3rd beta release of
version 1.2.3).
- rcX: Indicates a release candidate. X is an
integer indicating the number of the release candidate (e.g.,
v1.2.3rc4 indicates the 4th
release candidate of version 1.2.3).
- rV: Indicates the Subversion repository number
string that the release was made from (V is usually an
integer, but may have string qualifiers). Although all official Open
MPI and OpenRTE releases are tied to a single, specific Subversion repository
number (which can be obtained from the
ompi_info
command), only some releases have the Subversion repository number in
the version number. Development snapshot tarballs, for example, have
the Subversion repository included in the version to reflect that they
are a development snapshot of an upcoming release (e.g., v1.2.3r1234 indicates a development
snapshot of version 1.2.3 corresponding to Subversion repository
number 1234).
Quantifiers may be mixed together -- for example v1.2.3rc7r2345 indicates a development
snapshot of an upcoming 7th release candidate for version 1.2.3
corresponding to Subversion repository number 2345.
