Mon Mar 12 15:14:31 2012 UTC (7 years, 9 months ago) by schoenebeck
Original Path: linuxsampler/trunk/configure.in
File size: 57660 byte(s)
* Introduced new C++ API method EngineChannel::InstrumentFileName(int index)
  allowing to retrieve the whole list of files used for the loaded
  instrument on an engine channel (a.k.a. part). Some GigaStudio instruments
  for example are splitted over several files like "Foo.gig", "Foo.gx01",
  "Foo.gx02", ...
* Bumped version to 1.0.0.svn18

11     # The following is the libtool / shared library version. This doesn't have to
12     # do anything with the release version. It MUST conform to the following rules:
13     #
14     # 1. Start with version information of `0:0:0' for each libtool library.
15     # 2. Update the version information only immediately before a public release of
16     # your software. More frequent updates are unnecessary, and only guarantee
17     # that the current interface number gets larger faster.
18     # 3. If the library source code has changed at all since the last update, then
19     # increment revision (`c:r:a' becomes `c:r+1:a').
20     # 4. If any interfaces have been added, removed, or changed since the last update,
21     # increment current, and set revision to 0.
22     # 5. If any interfaces have been added since the last public release, then increment
23     # age.
24     # 6. If any interfaces have been removed since the last public release, then set age
25     # to 0.
