# Changelog for libavif slackbuild script
# --------------------------------------------------------------------

# 01/10/2022: Added to slackbuilds.org

# 06/01/2023: Updated README. Updated to github commit 93035c1
# Pandoc is used by libavif to build man pages. If you don't need
# manpages don't install pandoc and change the appropriate
# build option. For x86 architecture pandoc will be an optional dependency.
# pandoc needs to be built from sources for x86 architecture
#since it takes much time to build, I'm not building
# the manpages by default. If you need manpages
# install pandoc and then customize the slackbuild script by
# changing the build option for manpages from OFF to ON.

# 15/05/2023: updated to github commit 94352e0
# updated Deps in info file and README From this build onward man pages are not
# built by default hence pandoc will now be an optional dependency for all
#architectures. Gtest needs to be installed if want to build
# test during compile time, by default this is turned off.

# 06/02/2024: Updated to version 1.0.3
# 19/02/2024: Updated to version 1.0.4
# 14/08/2024: Updated to version 1.1.1
# 18/04/2025: updated to version 1.2.1
# 13/05/2025: Updated to version 1.3.0
