- Compose `Format=Flowed` messages with `format-flowed=true` in `aerc.conf`.
- Add a `trimSignature` function to the templating engine.
- Change local domain name for SMTP with `smtp-domain=example.com` in
  `aerc.conf`
- New column-based status line format with `status-columns`.
- Inline user-defined styles can be inserted in UI templates via the
  `{{.Style "name" string}}` function.

- Dynamic `msglist_*` styling based on email header values in stylesets.
- Add `mail-received`, `aerc-startup`, and `aerc-shutdown` hooks.
- Search/filter by flags with the `-H` flag.

### Changed

- Filters are now installed in `$PREFIX/libexec/aerc/filters`. The default exec
  `PATH` has been modified to include all variations of the `libexec` subdirs.
- The built-in `colorize` filter theme is now configured in styleset files into
  the `[viewer]` section.
- The standard Usenet signature delimiter `"-- "` is now prepended to
  `signature-file` and `signature-cmd` if not already present.
- All `aerc(1)` commands now interpret `aerc-templates(7)` markup.
- running commands (like mailto: or mbox:) no longer prints a success message
- The built-in `colorize` filter now emits OSC 8 to mark URLs and emails. Set
  `[general].enable-osc8 = true` in `aerc.conf` to enable it.
- Notmuch support is now automatically enabled when `notmuch.h` is detected on
  the system.

### Deprecated

  transports now assume `STARTTLS` and will fail if the server does not support
  it. To disable `STARTTLS`, use `smtp+insecure://`.

## [0.14.0](https://git.sr.ht/~rjarry/aerc/refs/0.14.0) - 2023-01-04

### Added

- View common email envelope headers with `:envelope`.
- Notmuch accounts now support maildir operations: `:copy`, `:move`, `:mkdir`,
  `:rmdir`, `:archive` and the `copy-to` option.
- Display messages from bottom to top with `[ui].reverse-msglist-order=true` in
  `aerc.conf`.
- Display threads from bottom to top with `[ui].reverse-thread-order=true` in
  `aerc.conf`.
- Style search results in the message list with `msglist_result.*`.
- Preview messages with their attachments before sending with `:preview`.
- Filter commands now have `AERC_FORMAT`, `AERC_SUBJECT` and `AERC_FROM`
  defined in their environment.

  `accounts.conf`.
- Search/filter by absolute and relative date ranges with the `-d` flag.
- LIST-STATUS and ORDEREDSUBJECT threading extensions support for imap.
- Built-in `wrap` filter that does not mess up nested quotes and lists.
- Write `multipart/alternative` messages with `:multipart` and commands defined
  in the new `[multipart-converters]` section of `aerc.conf`.
- Close the message viewer before opening the composer with `:reply -c`.
- Attachment indicator in message list flags (by default `a`, but can be
  changed via `[ui].icon-attachment` in `aerc.conf`).

  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
  the internal keyring exists and contains at least one key.
- Calling `:split` or `:vsplit` without specifying a size, now attempts to use
  the terminal size to determine a useful split-size.

### Fixed

  generated by `git send-email`.

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

### Added

- Change accounts while composing a message with `:switch-account`.
- Override `:open` handler on a per-MIME-type basis in `aerc.conf`.

  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`

  `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.

- 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

  `accounts.conf`.
- Mouse support for embedded editors when `mouse-enabled=true`.
- Numerous race conditions.

### Changed

  BSD.
- `outgoing-cred-cmd` execution is now deferred until a message needs to be sent.

  of `:view`.

  enabled at startup. This option no longer conflicts with `:toggle-threads`.

### Fixed

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

  this into account.
