Revision 2140 - (show annotations) (download)
Tue Oct 5 10:35:13 2010 UTC (8 years, 3 months ago) by schoenebeck
Original Path: linuxsampler/trunk/configure.in
File size: 56650 byte(s)
* raised limit of program change queue from 100 to 512
  (as suggested by Alex Stone)
* removed limit of maximum amount of MIDI ports per MIDI device, since
  there is no reason for this limit
* minor syntax simplification regarding 2 new LSCP commands: changed
  "SET FX_SEND SEND_EFFECT"" to "SET FX_SEND EFFECT" and changed
  "REMOVE FX_SEND SEND_EFFECT"" to "REMOVE FX_SEND EFFECT", also changed
  the respective category field of command "GET FX_SEND INFO" from
  "SEND_EFFECT" to "EFFECT"
* updated LSCP specification document
* bumped version to 1.0.0.cvs10

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.
