+- update to 0.20.0:
+  * Breaking changes
+    - jj rebase --skip-empty has been renamed to jj rebase
+      --skip-emptied
+    - jj backout --revision has been renamed to jj backout
+      --revisions.  The short alias -r is still supported.
+    - The default immutable_heads() set now includes
+      untracked_remote_branches() with the assumption that
+      untracked branches aren't managed by you. Therefore,
+      untracked branches are no longer displayed in jj log by
+      default.
+    - Updated defaults for graph node symbol templates
+      templates.log_node and templates.op_log_node.
+    - The "fileset" language is now enabled by default. It can
+      still be disable by setting ui.allow-filesets=false.
+    - On jj git fetch/import, commits referred to by HEAD@git are
+      no longer preserved. If a checked-out named branch gets
+      deleted locally or remotely, the corresponding commits will
+      be abandoned.
+    - jj --at-op=@ no longer merges concurrent operations if
+      explicitly specified.
+    - jj obslog -p no longer shows diffs at non-partial squash
+      operations.  Previously, it showed the same diffs as the
+      second predecessor.
+  * Deprecations
+    - The original configuration syntax for jj fix is now
+      deprecated in favor of one that allows defining multiple
+      tools that can affect different filesets.
+      These can be used in combination for now. See jj help fix for
+      details.
+  * New features
+    - External diff tools can now be configured to invoke the tool
+      on each file individually instead of being passed a directory
+      by setting
+      merge-tools.$TOOL.diff-invocation-mode="file-by-file" in
+      config.toml.
+    - In git diffs, word-level hunks are now highlighted with
+      underline. See diff colors and styles for customization.
+    - New .diff().<format>() commit template methods are added.
+      They can be used in order to show diffs conditionally. For
+      example, if(current_working_copy, diff.summary()).
+    - jj git clone and jj git init with an existing git repository
+      adds the default branch of the remote as repository settings
+      for revset-aliases."trunk()".`
+    - jj workspace forget now abandons the workspace's working-copy
+      commit if it was empty.
+    - jj backout now includes the backed out commit's subject in
+      the new commit message.
+    - jj backout can now back out multiple commits at once.
+    - jj git clone some/nested/path now creates the full directory
+      tree for nested destination paths if they don't exist.
+    - String patterns now support case‐insensitive matching by
+      suffixing any pattern kind with -i. mine() uses
+      case‐insensitive matching on your email address
+      unconditionally. Only ASCII case folding is currently
+      implemented, but this will likely change in the future.
+    - String patterns now support regex:"pattern".
+    - New tracked_remote_branches() and untracked_remote_branches()
+      revset functions can be used to select tracked/untracked
+      remote branches.
+    - The file() revset function now accepts fileset as argument.
+    - New diff_contains() revset function can be used to search
+      diffs.
+    - New command jj operation diff that can compare changes made
+      between two operations.
+    - New command jj operation show that can show the changes made
+      in a single operation.
+    - New config setting git.private-commits to prevent commits
+      from being pushed.
+    - The default commit description template can now be configured
+      by templates.draft_commit_description.
+    - jj fix can now be configured to run different tools on
+      different filesets.  This simplifies the use case of
+      configuring code formatters for specific file types. See jj
+      help fix for details.
+    - Added revset functions author_date and committer_date.
+    - jj describe can now update the description of multiple
+      commits.
+  * Fixed bugs
+    - jj status will show different messages in a conflicted tree,
+      depending on the state of the working commit. In particular,
+      if a child commit fixes a conflict in the parent, this will
+      be reflected in the hint provided by jj status
+    - jj diff --git no longer shows the contents of binary files.
+    - Windows binaries no longer require vcruntime140.dll to be
+      installed (normally through Visual Studio.)
+    - On quit, the builtin pager no longer waits for all outputs to
+      be discarded.
+    - jj branch rename no longer shows a warning in colocated
+      repos.

 %description
 Jujutsu is a Git-compatible DVCS. It combines features from Git (data model, speed), Mercurial (anonymous branching, simple CLI free from "the index", revsets, powerful history-rewriting), and Pijul/Darcs (first-class conflicts), with features not found in most of them (working-copy-as-a-commit, undo functionality, automatic rebase, safe replication via rsync, Dropbox, or distributed file system).
