dnl  Release instructions
dnl -----------------------------------------------
dnl
dnl  When you are about to release the software
dnl  either as a stable release or an unstable release
dnl  you should update the *_VERSION variables below
dnl  according to the following rules:
dnl
dnl  1. If any interfaces has been removed or changed,
dnl     increment MAJOR_VERSION and set others to 0
dnl  2. If any interface has been added,
dnl     increment MINOR_VERSION and set PATCH_VERSION to 0
dnl  3. If only the source code has changed,
dnl     increment PATCH_VERSION
dnl
dnl  If you are releasing a stable version,
dnl  set package version number in AC_INIT to
dnl  [$MAJOR_VERSION.$MINOR_VERSION.$PATCH_VERSION]
dnl
dnl  If you are releasing an unstable version,
dnl  add a string (i.e -alpha or -beta or -rc1) to the
dnl  package version in AC_INIT after $PATCH_VERSION
dnl  e.g. [$MAJOR_VERSION.$MINOR_VERSION.$PATCH_VERSION-rc1]
