Major versions are supposed to represent very large changes to the
|
||
|
|
library, minor versions indicate steady improvements (with odd minor
|
||
|
|
versions indicating unstable and undocumented development releases),
|
||
|
|
and micro versions indicating bug-fixes.

||
|
|
|
||
|
|

returns a static string representing the vips version number, and the date
|
||
|
|
when the library was built.
|
||
|
|
|
||
|
|
The version number always has three parts, separated by '.' characters. The
|
||
|
|
first part is the major release, the second the minor release (odd minor
|
||
|
|
values denote development releases), and the third the micro version number.
|
||
|
|
|
||
|
|
The version number and the date are separated by a '-' character.
|
||
|
|
|
||
|
|
The value of this string is constructed in 'configure.in'.
|
||
|
|
|
||
|
|
A typical value for tthe string might be "7.7.0-Thu Dec 16 18:10:01 GMT 1999".
