## [0.16.0](https://git.sr.ht/~rjarry/aerc/refs/0.16.0) - 2023-09-27
### Added
- JMAP support.
- The new account wizard now supports all source and outgoing backends.
- Edit email headers directly in the text editor with `[compose].edit-headers`
in `aerc.conf` or with the `-e` flag for all compose related commands (e.g.
`:compose`, `:forward`, `:recall`, etc.).
- Use `:save -A` to save all the named parts, not just attachments.

- Warn before sending emails with an empty subject with `empty-subject-warning`
in `aerc.conf`.

temporary file from which selected files will be read instead of the standard
output.
- Save drafts in custom folders with `:postpone -t <folder>`.
- View "thread-context" in notmuch backends with `:toggle-thread-context`.
### Fixed

- `:pipe <cmd>` now executes `sh -c "<cmd>"` as indicated in the man page.
### Changed
- Names formatted like "Last Name, First Name" are better supported in templates
- Composing an email is now aborted if the text editor exits with an error
(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`).
- `:export-mbox` only exports marked messages, if any. Otherwise it exports
everything, as usual.
- The local hostname is no longer exposed in outgoing `Message-Id` headers by
default. Legacy behaviour can be restored by setting `send-with-hostname
= true` in `accounts.conf`.
- The notmuch bindings were replaced with internal bindings
- Aerc now has a default style for most UI elements. The `default` styleset is
now empty. Existing stylesets will only override the default attributes if
they are set explicitly. To reset the default style and preserve existing
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
- Aerc can no longer be compiled and installed with BSD make. GNU make must be
used instead.

### Fixed
- Extra messages disappearing when deleting on maildir.

`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.

`aerc.conf`.
- Allow basic shell globbing in `[openers]` MIME types.
- 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
- `[ui].index-format` setting has been replaced by `index-columns`.

- Removed support for `[ui:subject...]` contextual sections in `aerc.conf`.
- `[triggers]` setting has been replaced by `[hooks]`.
- `smtp-starttls` setting in `accounts.conf` has been removed. All `smtp://`
transports now assume `STARTTLS` and will fail if the server does not support
it. To disable `STARTTLS`, use `smtp+insecure://`.

- 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`).
- Open file picker menu with `:attach -m`. The menu must be generated by an
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
- `:pipe -m git am -3` on patch series when `Message-Id` headers have not been
generated by `git send-email`.

- 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

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

- Multiple visual selections with `:mark -V`.
- Mark all messages of the same thread with `:mark -T`.
- Set default collapse depth of directory tree with `dirlist-collapse`.
### Changed
- Aerc will no longer exit while a send is in progress.

to avoid lagging. This can be configured with `client-threads-delay`.
- The provided awk filters are now POSIX compliant and should work on MacOS and
BSD.
- `outgoing-cred-cmd` execution is now deferred until a message needs to be sent.
- `next-message-on-delete` now also applies to `:archive`.

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