dnl MAKING RELEASES (a step-by-step guide!)
dnl ===============
dnl
dnl Since the last release:
dnl 1. if only source code (not the interface) has changed, set
dnl      IJS_MICRO_VERSION += 1;
dnl      IJS_INTERFACE_AGE += 1;
dnl 2. if any functions have been added, removed, or changed, set
dnl      IJS_INTERFACE_AGE = 0;
dnl      IJS_CURRENT_INTERFACE += 1;
dnl 3. if interfaces have been added, set
dnl      IJS_BINARY_AGE += 1;
dnl 4. if interfaces have been removed, set
dnl      IJS_BINARY_AGE = 0;
