What's Changed

🛠 Breaking Changes

• DVC used to identify a file by removing CRLF line endings (although it stored the original file contents in the cache).
  However, in DVC 3.x, this behaviour has been dropped.
  Now, DVC hashes the file contents directly without removing CRLF line endings.
  All pre-existing DVC-tracked data from DVC 2.x can still be accessed and used in DVC 3.x. However, any new operations that result in a DVC committed change will generate a 3.x DVC output, which will be stored in a different location than 2.x DVC outputs.
  The files will be stored in cache at .dvc/cache/files/md5 and in the remote at <remote_dir>/files/md5.

  You can read more about it in #4658 and #9538.

• While strictly not required, dvc cache migrate command is introduced to migrate 2.x format of cache to 3.x format to make migrations easier (#9591).

• Support for tracking (cached) external outputs has been removed (#9570).

• checkpoints has been removed (#9271).

• dvc run command has been removed, use stage add --run instead (#9508).

• exp init, exp gc commands have been removed (#9269, #9273).

• --show-json/--show-md/--show-csv flags are removed (#9475). Use --json/--md/--csv instead.

• --recursive option from dvc add is removed (#9513). Use dvc add dir to recursively add files in a directory.

• --file option from dvc add, dvc import and dvc import-url is now removed (#9547, #9562, #9548).

• --meta, --desc, --label, and --type option from dvc add, dvc import and dvc import-url is now removed (#9481).

• --jobs option that is used in combination with dvc add --to-remote is now renamed to --remote-jobs to avoid confusion with core.checksum_jobs (#9522, #9550).

• --metrics option is removed from both exp run and repro commands (#9458).

• --pcp option from exp show has been removed (#9270).

• Read-only support for dvc 1.0 lockfile format has been removed (#9476).

• Support for defining multiple plots as a dictionary has been removed (#9486). Use a list instead.

• dvc.yaml: stage-level vars is removed (#9556).

• use of .dvc file as a pipeline stage has been removed, which has been deprecated in 1.0. This means that now it is forbidden to use cmd/metrics/plots in .dvc files (#9546, #9551, #9552, #9554). Also, if you have used dvc before 1.0, Dvcfile is no longer supported or recognized.

• pkg info has moved from dvc.utils.pkg to dvc._build. You can now import it using from dvc import PKG (#9559).

🐛 Bug Fixes

• repro: check for hash mismatch between deleted dependencies and upstream outputs (#9533).
• exp list: show experiment shas (#9501).
• update: make sure we update hashes/checksums on --to-remote (#9536).
• fetch: cache collected (#9579).
