| == New Features == | == New Features == | ||||
| * clonebundles can be annotated with the expected memory requirements | |||||
| using the `REQUIREDRAM` option. This allows clients to skip | |||||
| bundles created with large zstd windows and fallback to larger, but | |||||
| less demanding bundles. | |||||
| * The `phabricator` extension now provides more functionality of the | |||||
| arcanist CLI like changing the status of a differential. | |||||
| * Phases processing is much faster, especially for repositories with | |||||
| old non-public changesets. | |||||
| == New Experimental Features == | == New Experimental Features == | ||||
| * The core of some hg operations have been (and are being) | |||||
| implemented in rust, for speed. `hg status` on a repository with | |||||
| 300k tracked files goes from 1.8s to 0.6s for instance. | |||||
| This has currently been tested only on linux, and does not build on | |||||
| windows. See rust/README.rst in the mercurial repository for | |||||
| instructions to opt into this. | |||||
| * An experimental config `rewrite.empty-successor` was introduced to control | |||||
| what happens when rewrite operations result in empty changesets. | |||||
| == Bug Fixes == | == Bug Fixes == | ||||
| * For the case when connected to a TTY, stdout was fixed to be line-buffered | |||||
| on Python 3 (where it was block-buffered before, causing the process to seem | |||||
| hanging) and Windows on Python 2 (where it was unbuffered before). | |||||
| * Subversion sources of the convert extension were fixed to work on Python 3. | |||||
| * Subversion sources of the convert extension now interpret the encoding of | |||||
| URLs like Subversion. Previously, there were situations where the convert | |||||
| extension recognized a repository as present but Subversion did not, and | |||||
| vice versa. | |||||
| * The empty changeset check of in-memory rebases was fixed to match that of | |||||
| normal rebases (and that of the commit command). | |||||
| * The push command now checks the correct set of outgoing changesets for | |||||
| obsolete and unstable changesets. Previously, it could happen that the check | |||||
| prevented pushing changesets which were already on the server. | |||||
| == Backwards Compatibility Changes == | == Backwards Compatibility Changes == | ||||
| * Mercurial now requires at least Python 2.7.9 or a Python version that | |||||
| backported modern SSL/TLS features (as defined in PEP 466), and that Python | |||||
| was compiled against a OpenSSL version supporting TLS 1.1 or TLS 1.2 | |||||
| (likely this requires the OpenSSL version to be at least 1.0.1). | |||||
| * The `hg perfwrite` command from contrib/perf.py was made more flexible and | |||||
| changed its default behavior. To get the previous behavior, run `hg perfwrite | |||||
| --nlines=100000 --nitems=1 --item='Testing write performance' --batch-line`. | |||||
| * The absorb extension now preserves changesets with no file changes that can | |||||
| be created by the commit command (those which change the branch name | |||||
| compared to the parent and those closing a branch head). | |||||
| == Internal API Changes == | == Internal API Changes == | ||||
| * logcmdutil.diffordiffstat() now takes contexts instead of nodes. | |||||
| * The `mergestate` class along with some related methods and constants have | |||||
| moved from `mercurial.merge` to a new `mercurial.mergestate` module. | |||||
| * The `phasecache` class now uses sparse dictionaries for the phase data. | |||||
| New accessors are provided to detect if any non-public changeset exists | |||||
| (`hasnonpublicphases`) and get the correponsponding root set | |||||
| (`nonpublicphaseroots`). | |||||
| * The `stdin`, `stdout` and `stderr` attributes of the `mercurial.pycompat` | |||||
| module were removed. Instead, the attributes of same name from the | |||||
| `mercurial.utils.procutil` module should be used, which provide more | |||||
| consistent behavior across Python versions and platforms. | |||||
