    - Other minor miscellaneous fixes and improvements; in particular,
      some improvements in cross-references.
  
 +* Obsolescent features:
 +
 +  - Use of suffix-less info files (that can be specified through the
 +    '@setfilename' macro in Texinfo input files) is discouraged, and
 +    its use will raise warnings in the 'obsolete' category.  Simply
 +    use the '.info' extension for all your info files, transforming
 +    usages like:
 +
 +        @setfilename myprogram
 +
 +    into:
 +
 +        @setfilename myprogram.info
 +
 +  - Use of Texinfo input files with '.txi' or '.texinfo' extensions
 +    is discouraged, and its use will raise warnings in the 'obsolete'
 +    category.  You are advised to simply use the '.texi' extension
 +    instead.
 +
  * Bugs fixed:
  
+   - When the 'ustar' option is used, the generated configure script no
+     longer risks hanging during the tests for the availability of the
+     'pax' utility, even if the user running configure has a UID or GID
+     that requires more than 21 bits to be represented.
+     See automake bug#8343 and bug#13588.
+ 
    - The obsolete macros AM_CONFIG_HEADER or AM_PROG_CC_STDC work once
      again, as they did in Automake 1.12.x (albeit printing runtime
      warnings in the 'obsolete' category).  Removing them has turned
