release notes

### Breaking changes


The minimum supported Rust version (MSRV) is now 1.71.0.


The storage format of branches, tags, and git refs has changed. Newly-stored

repository data will no longer be loadable by older binaries.


The : revset operator is deprecated. Use :: instead. We plan to delete the

: form in jj 0.15+.


The --allow-large-revsets flag for jj rebase and jj new was replaced by

a all: before the revset. For example, use jj rebase -d 'all:foo-'

instead of jj rebase --allow-large-revsets -d 'foo-'.


The --allow-large-revsets flag for jj rebase and jj new can no longer be

used for allowing duplicate destinations. Include the potential duplicates

in a single expression instead (e.g. jj new 'all:x|y').


The push.branch-prefix option was renamed to git.push-branch-prefix.


The default editor on Windows is now Notepad instead of pico.


jj will fail attempts to snapshot new files larger than 1MiB by default. This behavior

can be customized with the snapshot.max-new-file-size config option.


Author and committer signatures now use empty strings to represent unset

names and email addresses. The author/committer template keywords and

methods also return empty strings.

Older binaries may not warn user when attempting to git push commits

with such signatures.


In revsets, the working-copy or remote symbols (such as @, workspace_id@,

and branch@remote) can no longer be quoted as a unit. If a workspace or

branch name contains whitespace, quote the name like "branch name"@remote.

Also, these symbols will not be resolved as revset aliases or function

parameters. For example, author(foo@) is now an error, and the revset alias

'revset-aliases.foo@' = '@' will be failed to parse.


The root revset symbol has been converted to function root().


The ..x revset is now evaluated to root()..x, which means the root commit

is no longer included.


jj git push will now push all branches in the range remote_branches()..@

instead of only branches pointing to @ or @-.


It's no longer allowed to create a Git remote named "git". Use jj git remote rename to rename the existing remote.

#1690


Revset expression like origin/main will no longer resolve to a

remote-tracking branch. Use main@origin instead.


New features


Default template for jj log now does not show irrelevant information

(timestamp, empty, message placeholder etc.) about the root commit.


Commit templates now support the root keyword, which is true for the root

commit and false for every other commit.


jj init --git-repo now works with bare repositories.


jj config edit --user and jj config set --user will now pick a default

config location if no existing file is found, potentially creating parent directories.


jj log output is now topologically grouped.

#242


jj git clone now supports the --colocate flag to create the git repo

in the same directory as the jj repo.


jj restore gained a new option --changes-in to restore files

from a merge revision's parents. This undoes the changes that jj diff -r

would show.


jj diff/log now supports --tool <name> option to generate diffs by

external program. For configuration, see the documentation.

#1886


A new experimental diff editor meld-3 is introduced that sets up Meld to

allow you to see both sides of the original diff while editing. This can be

used with jj split, jj move -i, etc.


jj log/obslog/op log now supports --limit N option to show the first

N entries.


Added the ui.paginate option to enable/disable pager usage in commands


jj checkout/jj describe/jj commit/jj new/jj squash can take repeated

-m/--message arguments. Each passed message will be combined into paragraphs

(separated by a blank line)


It is now possible to set a default description using the new

ui.default-description option, to use when describing changes with an empty

description.


jj split will now leave the description empty on the second part if the

description was empty on the input commit.


branches()/remote_branches()/author()/committer()/description()

revsets now support exact matching. For example, branch(exact:main)

selects the branch named "main", but not "maint". description(exact:"")

selects commits whose description is empty.


Revsets gained a new function mine() that aliases author(exact:"your_email").


Added support for :: and .. revset operators with both left and right

operands omitted. These expressions are equivalent to all() and ~root()

respectively.


jj log timestamp format now accepts .utc() to convert a timestamp to UTC.


templates now support additional string methods .starts_with(x), .ends_with(x)

.remove_prefix(x), .remove_suffix(x), and .substr(start, end).


jj next and jj prev are added, these allow you to traverse the history

in a linear style. For people coming from Sapling and git-branchles

see #2126 for

further pending improvements.


jj diff --stat has been implemented. It shows a histogram of the changes,

same as git diff --stat. Fixes #2066


jj git fetch --all-remotes has been implemented. It fetches all remotes

instead of just the default remote


Fixed bugs


Fix issues related to .gitignore handling of untracked directories

#2051.


jj config set --user and jj config edit --user can now be used outside of any repository.


SSH authentication could hang when ssh-agent couldn't be reached

#1970


SSH authentication can now use ed25519 and ed25519-sk keys. They still need

to be password-less.


Git repository managed by the repo tool can now be detected as a "colocated"

repository.

#2011
