LLeMbas/CHANGELOG.md

Changelog

What changed, per version, for somebody using or running LLeMbas — not a restatement of the commit log. If a change fixed something that looked like it worked, that is worth a line: those are the ones nobody would otherwise know to stop working around.

Newest first. Versions are __version__ in src/lembas/__init__.py, which is the only place a version is written.

The first tagged release is 1.0.0. Everything below it shipped as a running deployment rather than as a release, and is recorded here so the release notes for 1.0.0 have something to be assembled from.

Unreleased

0.9.9

The first of five audit passes before 1.0.0 — everything that landed between 0.8.1 and 0.9.8 read as a whole rather than one feature at a time. This one is the main logic, the harness, and every instruction a model is given.

• Fixed: every model was told the time in a zone with no name. On any account that had not chosen a timezone — which is the default state of every account — the date line shipped as "Times the person gives you are in unless they say otherwise", on every request. The code claimed in two places that the line disappeared instead. It never had.

• Fixed: the prompt preview could not show most of what it previews. Eleven fragments are gated on things that only exist once there is a real chat, and the preview has none — so the whole agent surface, both scheduling fragments and the helper warning were missing from it whatever you ticked. Editing tool.agent and pressing preview showed a system message without tool.agent in it, and nothing said so. Two new controls come with the fix: what kind of chat to preview as, and which agent mode.

• Fixed: a model in Plan mode was told to use a tool it did not have. plan_update is withdrawn in that mode in favour of plan_submit, but its guidance appeared whenever a plan existed — directly under the line saying anything not in your tool list does not exist.

• Fixed: reading one knowledge document could fill the whole context window. Every other reader caps what it returns and says so; this one returned the document whole, and its description said "in full", so it did exactly what it claimed. A long PDF is now cut at 40,000 characters with the model told.

• Fixed: the guidance about helpers on a machine was wrong in both directions. It denied that a helper can write files, which is a documented option of the tool beside it, and it named seven of the twenty-three commands a helper may run — so a model avoided commands it was allowed to use. Both are now checked against the real list and the real schema by tests, because prose and a constant drift the moment one is edited alone.

• The tool description for delegating no longer claims a helper gets "the same tools". It gets deliberately fewer, and sizing a task against the wrong set is how a whole phase gets planned around something that will refuse it.

• The Updates page notices when the update helper on a host was installed for a different channel than the page follows. It is declared in two places — lembas.env and the systemd unit — and only the installer writes both, so editing one by hand would have left the button deploying something other than what the page named, with nothing anywhere saying so.

• Fixed: release notes from a signed tag rendered the signature block. _notes_for stripped the PGP header only, and which header appears depends on gpg.format — this repository signs with SSH.

• A CHANGELOG.md, kept from now on rather than assembled at release time.

0.9.8

Updates follow a channel, not a commit. stable tracks the newest vX.Y.Z tag; edge tracks the branch tip. A branch tip is not a release — following one means deploying whatever was pushed five minutes ago — so stable is the default for anybody who is not the person writing it.

• The Updates page shows a version rather than a commit sha: 1.0.0 at a tag, 1.0.0-7-gd4f56d seven commits past one, and a bare sha only before the first release exists.
• Release notes come out of the annotated tag itself, so no forge API is involved anywhere. That matters: the Gitea API this was checked against returns a 500 from a server-side panic on exactly the releases endpoint.
• A tag with a suffix (v1.1.0-rc1) is deliberately not a release — git's version sort ranks it above v1.1.0, so accepting one would step a stable host onto a candidate.
• Fixed: deploy/update.sh stopped silently after == fetching == on any host with no release tags — which was every host. Fetched, not reset, not restarted, and no error printed.
• Fixed: install.sh now refuses an ssh:// repository URL up front instead of letting the clone fail as a service user with no key.

0.9.7

Packaging, and updating without a shell.

• /admin/updates: what is running, what is available, and what changed between. A button applies it — answered by an opt-in systemd helper, because the service runs unprivileged and a web application that can restart its own service is one whose worst day is much worse. Without the helper the page says so and prints the command.
• Dockerfile and docker-compose.yml. No secret key, no data and no .git baked in; loopback only; a TLS proxy expected in front, because a service worker and a microphone both require HTTPS or localhost.
• deploy/lxc-install.sh creates an unprivileged Proxmox container and runs the existing installer inside it.
• /healthz, which opens the database rather than only proving the socket is listening.

0.9.6

Permissions, quotas and sharing.

• "What can this account actually do?" answered on screen, naming where each permission came from — admin, the baseline, or a group.
• Users and groups are list-plus-detail, and membership is edited from one side. It was on both, and a save from either overwrote what the other showed.
• Reading and writing split for notes, memory and skills.
• Quotas on a group — monthly tokens, concurrent replies, agent wall clock, images a day, helpers a reply. Resolved by maximum across a person's groups, with zero meaning no limit and winning outright.
• Fixed: deleting a group or an account left every share naming it behind. forget_principal had existed since shares did and was called by nobody.
• Fixed: library.share defaulted to off, so sharing shipped documented as done and unreachable — the panel only renders for somebody who holds it.
• The share panel is its own action with a search box. It used to be checkboxes inside the resource's save form, listing every account on the instance, and a tick only took effect if you also saved the resource.
• Reports are shareable, and every listing has a Shared with me filter.

0.9.5

Extraction settings, embeddings, and hybrid search.

• /admin/extraction: upload size, image edge, JPEG quality, PDF pages, extracted characters, orphan age, extra text extensions.
• An embedding model can be chosen from models flagged for it. Library search then fuses keyword and semantic ranking, so "how do I get paid" finds a document that says "invoicing".
• Choosing none is not a degraded mode: no rows written, no requests made, and byte-for-byte the keyword search that was always there.
• Vectors carry their model and width, and a mismatch is skipped rather than scored — comparing two embedding spaces produces a confident wrong answer.
• Indexing happens in the background as records are written, with a rebuild button for everything that already existed.

0.9.4

An instance can be somebody else's.

• Name, tagline, logo, favicon and launcher icons derived from the logo.
• The Middle-earth wording is editable data. Leaving a box alone does not freeze it, so a later release can still improve the default.
• Custom themes as a set of colours rather than a stylesheet, inheriting whichever built-in they start from.
• Global CSS overrides, served as /branding.css.

0.9.3

Subagents. A reply can hand a self-contained piece of work to a helper that runs on its own and reports back — several at once, so research fans out instead of queueing.

• A helper cannot ask questions, cannot send helpers of its own, writes nothing unless the call asked and the chat's mode allowed it, and on a machine runs only a fixed list of read-only commands — in every mode, including Auto.
• Fixed, and it was live in scheduled runs too: an unattended chat that hit an approval built a card nobody could see and sat on it for fifteen minutes.

0.9.2

Image generation defaults an administrator can actually set — steps, cfg, size, sampler, scheduler, denoise, negative prompt, checkpoint, batch. There were none: one hard-coded set from the SD1.5 era, and prose in a box as the only way to change it.

• The samplers and schedulers ComfyUI had been reporting all along are now the pickers; nothing had ever read them.
• The tool's own schema restates the instance's defaults, instead of telling the model "Default 512" beside an instance that draws at 1024.

0.9.1

Everything that arrives is announced, not only chat replies. A scheduled run that filed a report used to light a dot in a corner and say nothing.

• A count in the tab title while you are looking elsewhere.
• Web push, so a schedule firing at seven in the morning reaches a browser that is shut. Opt-in per device. It is the one thing here that contacts an outside service, and services/push.py says so plainly.

0.9.0

A model can schedule things. There was no tool for it — asked to "remind me every Monday", a model wrote a note and reported that it had scheduled something, and every screen agreed with it.

• schedule_create, schedule_list, schedule_update, schedule_cancel, over the same rule normaliser the manual form uses.
• The reply says the resulting timing back in words, which is the only moment anybody can check that Monday was understood as Monday.

0.8.3

An SSH connection may not point at this machine unless an administrator says so. A profile aimed at 127.0.0.1 walked straight past "nothing runs on the LLeMbas host" — through a real login, onto the machine holding the database and the encryption key. Three positions: off, one named port, or anywhere.

0.8.2

• Fixed: opening the canvas before a chat existed swapped the whole site into the panel. hx-get="" is not "fetch nothing" — htmx looks for the attribute, not the value, so the empty one was a real request for the current document.
• Fixed: the Canvas and Terminal buttons appeared where they could not work.
• The bottom edge of the shell is no longer drawn, so the sidebar footer and the composer stop meeting a line at two different heights.
• Admin pages scroll in one container; /admin/prompts no longer drops you at the bottom of a shorter panel.
