Greetings! The GCL team is happy to announce the release of version 2.6.14, the latest achievement in the 'stable' (as opposed to 'development') series. Please see http://www.gnu.org/software/gcl for downloading information.

This is a cleanup release with respect to 2.6.13, with the primary goal of supporting current gcc-12 signed integer tree-vrp optimizations, on by default at -O2 or higher.

There are a few portability fixes: X86_64_RELOC_SIGNED_1 support on macosx, centos readline/configure fixes, and R_RISCV_CALL_PLT support on riscv64.

A fix to decode-universal-time is included, which is backward incompatible with a workaround in currently released maxima. The gcl_cleanup... and/or master maxima branches in git have been adjusted accordingly.

'si::help has been imported into the "USER" package.
