# 24/01/2023: corrected spelling mistake in README and slack-desc.
# This will now build from lazarus source instead of
# relying on Debian source package.Thanks to Davild Miller
# For pointing that out.For the 64-bit systems I have added
# -march=x86-64 -mtune=native flag so it will be optimized
# for the host system, also added Hardening Flags.
# Bumped the build no.

#  version 2.2.6-0 in SBo.
