snac: update to 2.51. Changes:

Support for custom Emojis has been added; they are no longer hardcoded,
but read from the `emojis.json` file at the server base directory. Also,
they are no longer limited to string substitutions, but images as
external URLs are also supported (see `snac(8)` for more information).

Fixed a bug that caused some notifications to be lost when coming from a
user in the same instance.

Added an additional check for blocked instances (sometimes, posts from
blocked sites that were ancestors of legit posts were 'leaking' into the
timeline).

On OpenBSD, if the `disable_email_notifications` server flag is set to
`true`, `unveil()` is not called for the execution of the
`/usr/sbin/sendmail` binary and `pledge()` doesn't set the `exec`
promise.

Log message:
snac: update to 2.50. Changes:

Incoming posts can now be filtered out by content using regular
expressions on a server level (these regexes are written in the
`filter_reject.txt` file at the server base directory; see `snac(5)` and
`snac(8)`).

Improved page position after hitting the `Hide` or `MUTE` buttons (for
most cases).

Use a shorter maximum conversation thread level (also, this maximum
value is now configurable at compilation level with the
`MAX_CONVERSATION_LEVELS` define).

Fixed a bug where editing a post made the attached media or video
to be lost.

The way of refreshing remote actor data has been improved.

Posting from the command-line now allows attachments.

snac: update to 2.49. Changes:

- Mastodon API: Fixed a bug in how validated links are reported.
- Mastodon API: Fixed a bug in search by account.
- Mastodon API: Fixed missing `Video` type objects in timelines.
- Mastodon API: Added search by hashtag.
- Some cosmetic fixes to the web interface.

Log message:
snac: update to 2.48. Changes:

A new instance page, that shows all posts by users in the same instance
(like the public instance timeline, but interactive). This will help
building communities.

Follower-only replies to unknown users are not shown in timelines.

Added verification of metadata links: if the linked page contains a
link back to the snac user with a rel="me" attribute, it's marked
as verified.

Added a new server-level configuration parameter: `min_account_age`. If
this value (in seconds) is set in `server.json`, any activity coming
from accounts that were created newer than that will be discarded. This
can be used to mitigate spam.

Added a profile-page relation to links in webfinger responses
(contributed by khm).

Fixed some regressions and a crash.

Add snac: Simple, minimalistic ActivityPub instance

snac (Social Networks Are Crap) runs as a daemon, proxied by a
TLS-enabled real httpd server, and provides the basic services for a
Fediverse / ActivityPub instance: sharing messages and stuff from/to
other systems like Mastodon, Pleroma, Friendica, etc. Features:

- Lightweight, minimal dependencies
- Extensive support of ActivityPub operations, e.g. write public notes,
  follow users, be followed, reply to the notes of others, admire
  wonderful content (like or boost), write private messages...
- Multiuser
- Mastodon API support, so Mastodon-compatible apps can be used
- Simple but effective web interface
- Easily-accessed MUTE button to silence morons
- Tested interoperability with related software
- No database needed
- Totally JavaScript-free
- No cookies either
- Not much bullshit
