+* Version requirements:
+
+ - Autoconf 2.65 or greater is required.
+
* Obsolete features removed:
- Support for the "Cygnus-style" trees (once enabled by the 'cygnus'
* WARNING: Future backward-incompatibilities!
- - Autoconf 2.65 or later will be required by the next major Automake
- version (1.13). Until now, Automake has required Autoconf version
- 2.62 or later.
-
- Starting from the next major Automake version (1.13), the rules to
build pdf, ps and dvi output from Texinfo input will use the '--tidy'
option by default. Since such an option was introduced in Texinfo
# following tests, but some users were unable to figure out that their
# installation was broken since --version appeared to work.
