Wed Jul 2 22:24:02 2014 UTC (4 years, 6 months ago) by schoenebeck
File size: 58776 byte(s)
* Fixed virtual MIDI device event import (which caused i.e. the
  events from the virtual keyboard of gigedit to be ignored by the
  sampler).
* Bumped version (1.0.0.svn56).

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