Trylle

jj is a Git-compatible version control system that is both simple and powerful. See the installation instructions to get started.

It's the holidays, and this release was overall pretty quiet, without many major changes. Two select improvements:

Improvements to configuration management, including support for conditional variables in config files.
Large files in the working copy will no longer cause commands to fail; instead the large files will remain intact but untracked in the working copy.

Configuration variables are no longer "stringly" typed. For example, true is not converted to a string "true", and vice versa.
The following configuration variables are now parsed strictly: colors.<labels>, git.abandon-unreachable-commits, git.auto-local-bookmark, git.push-bookmark-prefix, revsets.log, revsets.short-prefixes signing.backend, operation.hostname, operation.username, ui.allow-init-native, ui.color, ui.default-description, ui.progress-indicator, ui.quiet, user.email, user.name
jj config list now prints inline tables { key = value, .. } literally. Inner items of inline tables are no longer merged across configuration files. See the table syntax documentation for details.
jj config edit --user now opens a file even if $JJ_CONFIG points to a directory. If there are multiple config files, the command will fail.
jj config set no longer accepts a bare string value that looks like a TOML expression. For example, jj config set NAME '[foo]' must be quoted as jj config set NAME '"[foo]"'.
The deprecated [alias] config section is no longer respected. Move command aliases to the [aliases] section.
jj absorb now abandons the source commit if it becomes empty and has no description.

--config-toml=TOML is deprecated in favor of --config=NAME=VALUE and --config-file=PATH.
The Signature.username() template method is deprecated for Signature().email().local().

jj command no longer fails due to new working-copy files larger than the snapshot.max-new-file-size config option. It will print a warning and large files will be left untracked.
Configuration files now support conditional variables.
New command options --config=NAME=VALUE and --config-file=PATH to set string value without quoting and to load additional configuration from files.
Templates now support the >=, >, <=, and < relational operators for Integer types.
A new Email template type is added. Signature.email() now returns an Email template type instead of a String.
Adds a new template alias commit_timestamp(commit) which defaults to the committer date.
Conflict markers are now allowed to be longer than 7 characters, allowing conflicts to be materialized and parsed correctly in files which already contain lines that look like conflict markers.
New $marker_length variable to allow merge tools to support longer conflict markers (equivalent to "%L" for Git merge drivers).
jj describe now accepts a JJ: ignore-rest line that ignores everything below it, similar to a "scissor line" in git. When editing multiple commits, only ignore until the next JJ: describe line.

The $NO_COLOR environment variable must now be non-empty to be respected.
Fixed incompatible rendering of empty hunks in git/unified diffs. #5049
Fixed performance of progress bar rendering when fetching from Git remote. #5057
jj config path --user no longer creates new file at the default config path.
On Windows, workspace paths (printed by jj root) no longer use UNC-style \\?\ paths unless necessary.
On Windows, jj git clone now converts local Git remote path to slash-separated path.
jj resolve no longer removes the executable bit on resolved files when using an external merge tool.

Thanks to the people who made this release happen!
