   5  * libmultipath ABI
   6  *
   7  * libmultipath doesn't have a stable ABI in the usual sense. In particular,
   8  * the library does not attempt to ship different versions of the same symbol
   9  * for backward compatibility.
  10  *
  11  * The ABI versioning only serves to avoid linking with a non-matching ABI, to
  12  * cut down the set of exported symbols, and to describe it.
  13  * The version string is LIBMULTIPATH_$MAJOR.$MINOR.$REL.
  14  *
  15  * Policy:
  16  *
  17  * * Bump $MAJOR for incompatible changes, like:
  18  *   - symbols removed
  19  *   - parameter list or return values changed for existing functions
  20  *   - externally visible data structures changed in incompatible ways
  21  *     (like offsets of previously existing struct members)
  22  *   In this case, the new version doesn't inherit the previous versions,
  23  *   because the new library doesn't provide the full previous ABI any more.
  24  *   All predecessors are merged into the new version.
  25  *
  26  * * Bump $MINOR for compatible changes, like adding symbols.
  27  *   The new version inherits the previous ones.
  28  *
  29  * * Bump $REL to describe deviations from upstream, e.g. in
  30  *   multipath-tools packages shipped by distributions.
  31  *   The new version inherits the previous ones.
