Pare numbers indicate a version with frozen API. I.e. you can
|
|
|
|
|
rely on the same set of features to be present in all
|
|
|
|
|
published releases with that major.minor.micro combination.
|

|
Odd numbers indicate that API upgrades are in progress.
|
|
|
|
|
I.e. new features might be already present or they might
|
|
|
|
|
be still missing. You need to check before compiling an
|
|
|
|
|
application which relies on freshly introduced features.

be still missing.

dynamic linking unless the proper library match can be
|

|
|
|
guaranteed by external circumstances.
