There are some hosts that keep returning 400 Bad Request to snac posts (e.g. hachyderm.io). I've investigated but still don't know where the problem is.
Implement the ActivityPub C2S (Client to Server) API: https://www.w3.org/TR/activitypub/#client-to-server-interactions . I skipped that part of the documentation entirely, so I don't know if this is trivial or hell. The Android client at http://andstatus.org/ implements it, or so it seems. There may be others.
The 'history' pages are just monthly HTML snapshots of the local timeline. This is ok and cheap and easy, but is problematic if you e.g. intentionally delete a post because it will remain there in the history forever. If you activate local timeline purging, purged entries will remain in the history as 'ghosts', which may or may not be what the user wants.
Add (back) the possibility to attach an image by URL.
With this new disk layout, hidden posts (and their children) can be directly skipped when rendering the HTML timeline (are there any other implications?).
Change the layout to be multi-user (2022-08-25T16:23:17+0200).
Read address:port from server.json (2022-08-26T09:14:08+0200).
Added an installation setup (2022-08-26T09:39:46+0200).

Add unfollow (2022-08-28T19:59:29+0200).
Generate the /outbox, unpaged, of the 20 latest entries, like what honk does (2022-08-29T14:29:48+0200).

If a `Like` or `Announce` is received from the exterior but the object is of a different user in the same instance, when the object is resolved a loop happens SNAC/activitypub.py:506: (2022-08-30T10:03:03+0200).
Ensure that likes and boosts are applied to the object instead of the container. More on this: for Mastodon, we're showing the '.../activity' link instead of the proper Note (2022-08-30T11:57:31+0200).
Fix signature checks (2022-08-30T18:32:22+0200).

Implement the 'one page' timeline (2022-09-04T05:41:07+0200).
Re-implement the renaming of updated messages in the local time (2022-09-04T05:58:51+0200).

Implement `Delete` + `Tombstone` on output (2022-09-07T09:42:09+0200).
Entries in the local timeline appear again after being shown in a thread. Try implementing an 'already shown entries' set (2022-09-07T11:21:52+0200).
The Delete button doesn't work for Likes and Announces (it points to the wrong message id) (2022-09-07T15:46:29+0200).
Document `server.json` in the admin manual (2022-09-08T11:01:43+0200).

Do not show `Like` or `Boost` buttons if that was already done (2022-09-12T19:29:04+0200).
Parents of a parent should also move up the timeline (2022-09-13T22:41:23+0200).
After 'Unfollow' or 'MUTE', the timeline should be rebuilt (regardless of the cached version) (2022-10-01T20:27:00+0200).
Should this user's notes with in_reply_to be resolved inside the object? (2022-10-01T20:27:52+0200).
Should admirations download the admired object into the timeline instead of resolving? (2022-10-01T20:27:52+0200).
Add a user configuration flag to hide likes from the timeline (2022-10-01T20:27:52+0200).
Implement an input queue (2022-10-01T20:27:52+0200).
Refactor HTML rendering because it's a mess and write build_timeline(), that generates a big structure with everything to show in a timeline, to be passed to the HTML renderer (2022-10-01T20:27:52+0200).
build_mentions() should not query the webfinger (and it's disabled by now); process_message() should 'complete' the tag Mentions that don't include a host (2022-10-10T09:45:57+0200).
Dropping on input those messages that have their parent hidden is not a good idea, as children of *these* dropped messages will pass unharmed (2022-11-28T11:34:56+0100).
Idea for a new disk layout: timelines stored like in git (2 character directories and then the md5.json inside); one append-only index with entry ids, read backwards (easy because md5 binary ids have a constant size); children lists as append-only files stored inside the timeline directories with almost the same names as the parent entry; liked-by and announced-by lists as append-only files of actor ids. No _snac metadata inside the message (But, what about the referrer? With this layout, do I need it?). The instance storage may even be global, not per user; this could help in very big instances (but will this be a use-case for snac? not probably) (2022-12-04T06:49:55+0100).
Add an ?skip=NNN parameter to the admin page, to see older timeline (2022-12-08T08:41:11+0100).
Now that we have the 2.7 layout and Likes and Announces don't move the conversations up, finally fix the ugly # positioning (2022-12-08T08:41:27+0100).
Implement hashtags. They are not very useful, as they can only be implemented as instance-only (not propagated), but it may help classifiying your own posts (2023-01-26T14:39:51+0100).
If there is a post in private.idx that has a parent that is in the global object database, this parent will be inserted into the list by timeline_top_level(). BUT, the new function timeline_get_by_md5() (that only looks in the user caches) won't find the parent, so the full thread will not be shown. This is BAD (2023-02-08T13:48:12+0100).
Move the output messages to the global queue (2023-02-10T12:17:30+0100).
Refactor the global queue to use a pool of threads (2023-02-10T12:17:38+0100).
Add a user-settable `purge_days`. This is not at first very hard to do, but purging posts from a user cache directory does not also delete them from the global object database and they will be kept in the indexes (unless they are also deleted from the indexes, which is a too expensive operation); this way, if another user in the same instance follows you, your posts will not disappear as you desire and that may be confusing and annoying. A different way to implement this: configure a maximum number of entries to keep and truncate the indexes in the purge. But this does not clear the disk usage, which is why I want to implement this (to implement bots that generate posts periodically and avoid the disks exploding) (2023-02-10T12:18:42+0100).
Add support for uploading the avatar, instead of needing an URL to an image. As a kludgy workaround, you can post something with an attached image, copy the auto-generated URL and use it. You can even delete the post, as attached images are never deleted (I said it was kludgy) (2023-02-15T09:31:06+0100).
