gnash 1.3.1

Bug-fix release over 1.3.0.

Fixes

Arithmetic base#number notation now evaluates to the value, not the base:
$((16#ff)) → 255, $((2#101)) → 5, $((10#42)) → 42 (bases 2–64).
set -o pipefail is now honored — a pipeline's exit status is the last
(rightmost) command to exit non-zero, instead of always the last stage's.

Both are fixes in the shared Bourne engine, so they apply under every personality
(bash/zsh/ksh/ash).
