v0.17.0

This release focuses on keeping Kart secure and performant, as well as polishing existing features.

New features

• New kart mv command to rename dataset paths. #1067

Breaking changes

• No longer building MacOS builds for Intel Macs, only building for Apple Silicon Macs. Please get in touch if this is a concern for you.
• Patch format (apply command) now uses unambiguous keys for feature changes - ++ for inserts, -- for deletes, and +/- for updates. This matches the delta-filter format used in diffs.

Other changes

• Patches (apply/create-patch) have been significantly improved:
  • Partial feature updates (updated features don't need to include unchanged fields) #1065
  • Reprojected patches (patch CRS is specified via crs in the patch metadata) #1066
• merge: --message/-m option no longer implies --no-ff. The message will now be used if the command can't do a fast-forward. #1051
• diff/show:
  • Fixed garbled json-lines output sometimes when using --add-feature-count-estimate #1040
  • Faster output for some large repositories (varies wildly) #1038
  • Text output now consistently displays a 'Merge: {parentIDs}' line when showing a merge commit #1043
  • show: Added --no-sort-keys option to disable sorting of features by name/PK. Previously added to diff only
  • show: Added --add-feature-count-estimate option to add a feature count estimate to json-lines output. Previously added to diff only
  • Fixed some issues with the built-in visual HTML diff ie kart show -ohtml

v0.16.1

0.16.1

• diff: Much faster and much lower memory usage when using --no-sort-keys #1032
• diff: Fix an error when diffing a commit against the working copy, where a dataset has been deleted since the commit. #1033
• Custom CRS support in MSSQL server - OGR conventions are used to store custom CRSs in a spatial_ref_sys table. #1036

v0.16.0

0.16.0

• Much faster access to tabular/vector datasets (about 75% more features processed per second) by switching to msgspec - #1025
• diff: Faster JSON-Lines output (also using msgspec)
• diff: Added --no-sort-keys option to disable sorting of features by name/PK. This is a minor speed improvement.
• Linux builds now require glibc 2.28+ #1027 - This means minimum distro versions are:
  • Debian 10+
  • Ubuntu 18.10+
  • Fedora 29+
  • RHEL/Rocky/AlmaLinux 8+
• Upgrade to PDAL 2.7 #1005
• Adds a --drop-empty-geometry-features option to kart export. #1007
• Adds diagnostic output to Kart when KART_DIAGNOSTICS=1 environment variable is set. #1013
• In kart merge --output-format=json, the message field is now null if the merge is a no-op. #1021

v0.15.3

Changes

• Replaces minimal patches with delta-filters - a more general-purpose way of filtering parts (inserts, updates, deletes) of JSON diffs when not all parts are required. #998
• Remove automatic resolution of localhost before calling MSSQL driver. Fixes SQL Server instance names issue. #999
• Upgraded pyodbc for compatibility with the latest MSSQL driver.

v0.15.2

Changes

• Adds a new command kart export which enables export of vector or tabular datasets to any OGR format. #992

v0.15.1

Changes

• Prevented committing local changes to linked datasets. #953
• Fixes a bug where even datasets marked as --no-checkout are checked out when the working copy is first created. #954
• Fixes a bug where minor changes to auxiliary metadata (.aux.xml) files that Kart is supposed to ignore were preventing branch changes. #957
• Improved performance when the user filters a diff request to only show certain features. #962
• Clean up the empty directory if a clone fails outright. #963
• Fixes add-dataset to work for PostGIS working copies. #965
• Fixes kart import --link to not fetch any tiles when importing into a bare Kart repo. #970

v0.15.0

Major changes

• First and foremost: linked datasets! Kart now supports linking a tile-based dataset to tiles that are hosted on S3, so that the tiles don't need to be hosted on a Kart LFS server. For more information, see Linked Datasets. #905

Other changes

• Native Apple Silicon builds are now available for macOS 12 and newer. #927
• Adds support for disabling the working-copy checkout of specific datasets using the commands kart import DATASET --no-checkout or kart checkout --not-dataset=DATASET, and re-enabling it using kart checkout --dataset=DATASET. #926
• Adds information on referencing and citing Kart to CITATION. #914
• Fixes a bug where Kart would misidentify a non-Kart repo as a Kart V1 repo in some circumstances. #918
• Improve schema extraction for point cloud datasets. #924
• Some tweaks to --dry-run output of Kart LFS commands. #932
• Now using Python 3.11 to build Kart, and vendored dependencies have been updated to newer versions. #933
• Adds support for importing point-cloud and raster tiles directly from an S3 URL. #940
• checkout: Smoother progressbar updates
• Add library support for WEBP & ZSTD compression with GeoTIFF raster datasets. #951

v0.14.2

Changes

• Fixes a bug where the GPKG application ID is not being written in GPKG working copies - other software reading the GPKG may be confused by this. #902
• Fixes a bug where points could shift by small amounts while importing point-clouds if the tiles were converted to COPC. PDAL#4180

v0.14.1

Changes

• Fixes a bug where Git subprocesses (such as git clone) don't prompt the user for credentials or to resolve SSH issues on Windows. #852
• Better protection against XSS in the HTML diff viewer. #884
• Speed-up: greatly reduces the time taken to update the index file after checking out LFS tiles to the working copy. #880
• Adds --with-dataset-types option to kart data ls command (and deprecates kart data version). #892
• Use journal_mode = WAL in annotations.db sqlite database. #898
• Slightly modifies the GPKG working copy format to avoid an incompatiblity with Global Mapper. #899
