    - Automatic dependency tracking now works also with the IBM XL C/C++
      compilers, thanks to the new new depmode 'xlc'.
  
 +Bugs fixed in 1.11.3a:
 +
 +* Bugs introduced by 1.11.3:
 +
 +  - NONE YET
 +
 +* Bugs introduced by 1.11.2:
 +
 +  - A definition of 'noinst_PYTHON' before 'python_PYTHON' (or similar)
 +    don't cause spurious failures upon "make install" anymore.
 +
 +* Long-standing bugs:
 +
 +  - It is now possible for a foo_SOURCES variable to hold Vala sources
 +    together with C header files, as well as with sources and headers for
 +    other supported languages (e.g., C++).  Previously, only mixing C and
 +    Vala sources was supported.
 +
++  - If "aclocal --install" is used, and the first directory specified with
++    '-I' is non-existent, aclocal will now create it before trying to copy
++    files in it.

 +New in 1.11.3:
 +
 +* Miscellaneous changes:
 +
    - Automake's own build system is more silent by default, making use of
      the 'silent-rules' option.
