## [Unreleased]

### Breaking changes

### New features

### Fixed bugs

## [v0.5.0] - 2025-09-29

### New features

* `diffedit3` now accepts files as arguments, not just dirs. So, `diffedit3
  left_file right_file output_file` is now allowed. Mixing dirs and files is not
  allowed.

* When used on a single file, `diffedit3` now permanently stays in "pinned" mode
  and the pinning/collapsing controls are disabled. Allowing the user to
  collapse the only editor doesn't make much sense.

## [v0.4.0] - 2024-05-04

### Breaking changes

* The `--port-range` option was removed. Instead, `--port` can now be repeated and accepts dash-separated ranges. For example, the default is now equivalent to `--port 8080-8090 --port 0`.

* This also corresponds to a breaking change to the `local_server` library interface

## [v0.3.0] - 2024-04-11

Make `diffedit3` easier to install

### Breaking changes

Renamed the `diffedit3-web` binary to `diffedit3`

The `diffedit3-gui` release artifact is now marked as unsupported in
its name.

### New features

`diffedit3` can now be installed with `cargo binstall diffedit3`.

### Fixed bugs


## [v0.2.0] - 2024-04-05

### Breaking changes

* Major version update to `poem` dependency

### New features

### Fixed bugs

* A bug that prevented saving the comparison when a file's dir existed on the
  left side but not on the right side.

### Maintenance

* There are now some tests; GitHub CI runs them.


## [v0.1.2] - 2024-03-18

### New features

* The editor now supports a "pinned" mode where one file merge takes up the
  whole app window.

* Minor visual design fixes/improvements

## [v0.1.1] - 2024-03-15

Mostly some internal code reorganization.

### New features

* `diffedit3` now has a logo (and an icon, and a favicon). See the top of the
  README. :)


## [v0.1.0] - 2024-03-13

### Breaking changes

* The library package is renamed to `diffedit3`, with a binary called
  `diffedit3-web`. The Tauri binary is still called `diffedit3-gui`.
  
* Line-wrapping defaults to on

### New features

* The web server version of diffedit3 can be used as a library

* Line-wrapping, collapsing of long identical regions, and aligning of changes
  using blank lines can now be toggled in the editor.

* It is now possible to remove the right pane for a 2-pane view (left pane &
  output pane only)

* Binary and files over 200KiB will not be compared.

* diffedit3-web: new --port-range option allows trying a different port if the
  first port we try is already in use (e.g. another instance of diffedit3-web is
  running)

* diffedit3-web: a simple security check is added so that the tool will not
  overwrite files it wasn't meant to compare.

### Fixed bugs
