v0.12.3

• Fix the issue where re-importing the same shapefile with --replace-existing would show spurious schema changes (and therefore row changes). #791
• Added support for committing new layers to a kart repository with add-dataset and the table name. #249
• Switched the crs84Extent field for point-cloud tiles to store a 4-point-polygons (instead of an axis-aligned envelope). #809
• Improved progress reporting when importing tiles, in line with working copy checkout.
• Added support for --diff-format option under kart show command to display different level of detail depending on the user's needs. #721
• Allow for automatically resolving primary key conflicts during a merge using kart resolve --renumber=(ours|theirs) #814
• Improved tile import performance for point-cloud (and eventually raster) by making it multithreaded. #818
• Fixed a bug where Kart would require user.name and user.email to be set, even when GIT_AUTHOR_EMAIL and similar variables were set in the environment. #812
• Update native dependencies. #820
• Drop CI testing of Debian Stretch/oldoldstable. #820
