# Update to latest LibRaw-201903 snapshot at d4f05dd1b9b2d44c8f7e82043cbad3c724db2416
# LibRaw publishes:
# - snapshots every 5-7 months (in master branch)
# - releases (0.18, 0.19, etc.) every 1-1.5 years.
# - security hotfixes for releases (0.19.1, 0.19.2, etc.)
# Hence, from user point of view, it is practical to refer to the latest snapshot,
# instead of the latest release.
