Programs using the previous version may use the new version as drop-in 25 # replacement, and programs using the new version can also work with the 26 # previous one. In other words, no recompiling nor relinking is needed. 27 # In this case, bump revision only, don't touch current nor age. 28 # 29 # 2. Programs using the previous version may use the new version as drop-in 30 # replacement, but programs using the new version may use APIs not 31 # present in the previous one. In other words, a program linking against 32 # the new version may fail with unresolved symbols if linking against 33 # the old version at runtime: set revision to 0, bump current and age. 34 # 35 # 3. Programs may need to be changed, recompiled, relinked in order to use 36 # the new version.
