1 == New Features ==

     2 

     3  * New config `commands.commit.post-status` shows status after successful

     4  commit.

     5 

     6  * `hg root` now has templating support, including support for showing

     7    where a repo share's source is. See `hg help -v root` for details.

     8 

     9  * New `--force-close-branch` flag for `hg commit` to forcibly close

    10    branch from a non-head changeset.

    11 

    12  * The curses-based interface for commands like `hg commit -i` now supports

    13    a range-select mechanism. Select the first line using space like before,

    14    navigate to the last line, and press X (capital x) to set all items in

    15    the range at once. Lowercase x has been added as a synonym for space to

    16    help reinforce the mechanism, and pressing enter/return continues to be a

    17    synonym for "toggle the current line and move down to the next item in

    18    this section."

    19 

    20 == New Experimental Features ==

    21 

    22  * New config `experimental.log.topo` makes `hg log -G` use

    23    topological sorting. This is especially useful for aliases since it

    24    lets the alias accept an `-r` option while still using topological

    25    sorting with or without the `-r` (unlike if you use the `sort(...,

    26    topo)` revset).

    27 

    28 

    29 == Bug Fixes  ==

    30 

    31  * issue4292: "hg log and {files} {file_adds} {file_mods} {file_dels}

    32    in template show wrong files on merged revision". See details in

    33    "Backwards Compatibility Changes".

    34 

    35 

    36 == Backwards Compatibility Changes ==

    37 

    38  * Removed (experimental) support for log graph lines mixing

    39    parent/grandparent styles. Setting

    40    e.g. `experimental.graphstyle.parent = !` and

    41    `experimental.graphstyle.grandparent = 3.` would use `!` for the

    42    first three lines of the graph and then `.`. This is no longer

    43    supported.

    44 

    45  * If `ui.origbackuppath` had been (incorrectly) configured to point

    46    to a file, we will now replace that file by a directory and put

    47    backups in that directory. This is similar to how we would

    48    previously replace files *in* the configured directory by

    49    subdirectories.

    50 

    51 * Template keyword `{file_mods}`, `{file_adds}`, and `{file_dels}`

    52    have changed behavior on merge commits. They used to be relative to

    53    the first parent, but they now consider both parents. `{file_adds}`

    54    shows files that exists in the commit but did not exist in either

    55    parent. `{file_dels}` shows files that do not exist in the commit

    56    but existed in either parent. `{file_mods}` show the remaining

    57    files from `{files}` that were not in the other two

    58    sets.

    59 

    60 

    61 == Internal API Changes ==

    62 

    63  * Matchers are no longer iterable. Use `match.files()` instead.

    64 

    65  * `match.visitdir()` and `match.visitchildrenset()` now expect the

    66    empty string instead of '.' to indicate the root directory.

    67 

    68  * `util.dirs()` and `util.finddirs()` now include an entry for the

    69    root directory (empty string).

    70 

    71  * shelve is no longer an extension now. it will be turned on by default.

    72 

    73  * New API to manage unfinished operations: Earlier there were distinct APIs

    74    which dealt with unfinished states and separate lists maintaining them

    75    that are `cmdutil.afterresolvestates`, `cmdutil.unfinishedstates` and

    76    `cmdutil.STATES`. Now these have been unified to a single

    77    API which handles the various states and their utilities. This API

    78    has been added to `state.py`. Now instead of adding to these 3 lists

    79    independently a state for a new operation can be registered using

    80    `addunfinished()` in `state` module.

    81 

    82  * `cmdutil.checkunfinished()` now includes detection for merge too.

    83 

    84  * merge abort has been disallowed in case an operation of higher

    85    precedence is in progress to avoid cases of partial abort of

    86    operations.

    87 

    88  * We used to automatically attempt to make extensions compatible with

    89    Python 3 (by translating their source code while loading it). We no

    90    longer do that.
