# Changelog for pocketsphinx SlackBuild Script
# --------------------------------------------------------------------

# 03/09/2022: Added to SBo

# 14/07/2023: Updated to github commit id 8221706.This version joins Opencv4 and lensfun
# in not compiling with FFmpeg. FFmpeg will detect pocketsphinx but it will eventually
# run into error during compilation.This seems to be FFmpeg upstream problem so
# don't enable pocketsphinx in FFmpeg when you try to recompile it.

# 19/02/2024: Updated to version 5.0.3. Removed python plugin.
# one of the reasons why pocketsphinx fails to build with FFmpeg is due to
# intentional API break in pocketsphinx. This is an upstream FFmpeg
# problem see https://trac.ffmpeg.org/ticket/10520

# 18/02/2025: Updated to version 5.0.4
