- Replying to all will include the Sender in Cc.
- Add `-b` flag to the `:view` command to open messages in a background tab.
- `AERC_ACCOUNT` and `AERC_FOLDER` are now available in the signature command
  environment.

- Forwarded messages can now be searched for and filtered in notmuch and
  maildir.
- Forwarded messages can be styled differently in the message list.
- Forwarded messages can be identified with the `{{.IsForwarded}}` template.
- The `:flag` command now sets/unsets/toggle the forwarded tag.
- The notmuch backend now honors the forwarded flag, setting the `passed` tag.
- The maildir backend now honors the `forwarded`/`passed` flag.
- Auto-switch projects based on the message subject for the `:patch` command.
- New `:echo` command that prints its arguments with templates resolved.

- Command completion now displays descriptions next to completion items.
- New `completion_description` style object in style sets used for rendering
  completion item descriptions.
- `:import-mbox` can now import data from an URL.

- The JMAP backend now supports full thread fetching and caching (limited
  within a single mailbox).
- `:expand-folder` and `:collapse-folder` can now act on a non selected folder.
- Filters commands can now provide their own paging by prefixing them with a
  `!` character. Doing so will disable the configured `[viewer].pager` and
  connect them directly to the terminal.
- Reply to addresses in `From` and `Reply-To` headers with `:reply -f`.

### Fixed

- Builtin `calendar` filter shows empty attendee list.
- Terminal-based pinentry programs (e.g. `pinentry-curses`) now work properly.
- Failure to create IPC socket on Gentoo.
- Notmuch searches which explicitly contain tags from `exclude-tags` now return
  messages.

- Remove unwanted less than symbol from In-Reply-To header when Message-ID uses
  folding.
- Aliases are now taken into account correctly when replying to own messages
  such as from the Sent folder or via a mailing list.
- Some SMTP servers do not strip `Bcc` headers. aerc now removes them before
  sending emails to avoid leaking private information. A new `strip-bcc =
  false` option can be used in `accounts.conf` to revert to previous behaviour
  (preserve `Bcc` headers in outgoing messages).
- There should no longer be any duplicates in recipient lists when replying.
- GPG signatures and encrypted parts now use CRLF line endings as required by
  RFC 5322.

### Changed

- Template function `quote` only prefixes with a space if at quote depth `1`.

  of `{{.OriginalText}}`.
- The location of the command history file has changed to
  `${XDG_STATE_HOME:-$HOME/.local/state}/aerc/history`.
- Tab completions for text fields are run asynchronously. In-flight requests
  are cancelled when new input arrives.
- Path completion now uses the normal filtering mechanism, respecting case
  sensitivity and the fuzzy completion option.
- The `html` filter is now enabled by default, making `w3m` a weak runtime
  dependency. If it is not installed, viewing HTML emails will fail with an
  explicit error.
- The default `text/html` filter will now run `w3m` in interactive mode.
- The builtin `html` and `html-unsafe` filters can now take additional
  arguments that will be passed to `w3m`. This can be used to enable inline
  images when viewing `text/html` parts (e.g.: `text/html = ! html-unsafe
  -sixel`).
- The templates `exec` commands is now executed with the `filters` exec `$PATH`
  similar to filter commands.
- The default `quoted_reply` template now converts `text/html` parts to plain
  text before quoting them.

### Added

- JMAP support.
- The new account wizard now supports all source and outgoing backends.

  (e.g. with `vim`, abort an email with `:cq`).
- Aerc builtin filters path (usually `/usr/libexec/aerc/filters`) is now
  **prepended** to the default system `PATH` to avoid conflicts with installed
  distro binaries which have the same name as aerc builtin filters (e.g.
  `/usr/bin/colorize`).

  stylesets appearance, these two lines must be inserted **at the beginning**:

  ```
  *.default=true
  *.normal=true
  ```
- Openers commands are not executed in with `sh -c`.

### Deprecated

  external command configured via `[compose].file-picker-cmd` in `aerc.conf`.
- Sample stylesets are now installed in `$PREFIX/share/aerc/stylesets`.
- The built-in `colorize` filter now has different themes.

### Changed

- `pgp-provider` now defaults to `auto`. It will use the system `gpg` unless

## [0.13.0](https://git.sr.ht/~rjarry/aerc/refs/0.13.0) - 2022-10-20

### Added

- Support for bindings with the Alt modifier.
- Zoxide support with `:z`.
- Hide local timezone with `send-as-utc = true` in `accounts.conf`.
- Persistent command history in `~/.cache/aerc/history`.
- Cursor shape support in embedded terminals.
- Bracketed paste support.
- Display current directory in `status-line.render-format` with `%p`.
- Change accounts while composing a message with `:switch-account`.
- Override `:open` handler on a per-MIME-type basis in `aerc.conf`.
- Specify opener as the first `:open` param instead of always using default
  handler (i.e. `:open gimp` to open attachment in GIMP).
- Restored XOAUTH2 support for IMAP and SMTP.
- Support for attaching files with `mailto:`-links
- Filter commands now have the `AERC_MIME_TYPE` and `AERC_FILENAME` variables
  defined in their environment.
- Warn before sending emails that may need an attachment with
  `no-attachment-warning` in `aerc.conf`.
- 3 panel view via `:split` and `:vsplit`
- Configure dynamic date format for the message viewer with
  `message-view-this-*-time-format`.
- View message without marking it as seen with `:view -p`.

### Changed

- `:open-link` now supports link types other than HTTP(S)
- Running the same command multiple times only adds one entry to the command
  history.
- Embedded terminal backend (libvterm was replaced by a pure go implementation).
- Filter commands are now executed with
  `:~/.config/aerc/filters:~/.local/share/aerc/filters:$PREFIX/share/aerc/filters:/usr/share/aerc/filters`
  appended to the exec `PATH`. This allows referencing aerc's built-in filter
  scripts from their name only.

### Fixed

- `:open-link` will now detect links containing an exclamation mark
- `outgoing-cred-cmd` will no longer be executed every time an email needs to
  be sent. The output will be stored until aerc is shut down. This behaviour
  can be disabled by setting `outgoing-cred-cmd-cache=false` in
  `accounts.conf`.
- Mouse support for embedded editors when `mouse-enabled=true`.
- Numerous race conditions.

- Set default collapse depth of directory tree with `dirlist-collapse`.

### Changed

  to avoid lagging. This can be configured with `client-threads-delay`.

  BSD.
- `outgoing-cred-cmd` execution is now deferred until a message needs to be sent.
- `next-message-on-delete` now also applies to `:archive`.
- `:attach` now supports path globbing (`:attach *.log`)

### Fixed

- Transient crashes when closing tabs.
- Binding a command to `<c-i>` and `<c-m>`.
- Reselection after delete and scroll when client side threading is enabled.
- Background mail count polling when the default folder is empty on startup.
- Wide character handling in the message list.
- Issues with message reselection during scrolling and after `:delete` with
  threading enabled.

### Fixed

- Messages that have failed `gpg` encryption/signing are no longer sent.
- Recalling attachments from drafts.
