0.6.2

Released 2026-11-06.

Added memory cards to the web pages: /web and /web/admin list memories as paged cards you can filter by state, workarea, origin, author key and text, and draw the workareas you may read as an Atlas, a treemap the server draws with no script.
Added a dropdown on each workarea in the web pages for its acts, each confirmed before it runs.
Added open sign-up, off by default. With signup.mode = open, a person who signs in with Google or GitHub and holds no entry reaches a terms page, then gets a private root under quotas, a reviewer key of their own and a /web/start page that walks them through the first memory. A person can ask for their account to be deleted. Migration 0037 runs at upgrade. Nothing changes for you unless you set the mode.
Changed the web pages, the documentation site and the README to one design system, with the same colours, type and state marks everywhere.
Changed the landing page to lead with one memory across your AI tools, with a page for teams and one for individuals.
Changed the documentation to be grouped by what a reader does, with open work tracked as GitHub issues.
Changed continuous integration to run only the jobs a pull request's changed paths reach.

Upgrade notes: Migration 0037 runs at upgrade. Open sign-up stays off until you set signup.mode = open.

0.6.1

Released 2026-11-06.

Added claim formats: a write may name a format (plain text, Markdown, Mermaid, JSON, YAML or code) and a one-line title; the format is signed with the version and changes only by replacement. Migrations 0032 to 0034 run at upgrade.
Added the Rust adapter for oml sync, which reads a Cargo workspace as one claim per crate and one per module doc.
Added titles to the MCP tools (Remember, Recall and Workarea) and rewrote the server instructions to describe what recall returns instead of telling the model to call it.
Added oml keys connect-code --ttl, which mints a connect code that lives up to 30 days, only for a key confined to one workarea other than the universe.
Added oml demo seed <workarea>, which fills a workarea with thirty demonstration memories.
Changed the connect page to say where the code comes from, with a link to your account page.
Changed a handler panic to answer a named 500 system.internal with the request id; oml doctor warns when any occurred.

Upgrade notes: Migrations 0032 to 0034 run at upgrade.

0.6.0

Released 2026-11-06.

Added in-progress workareas: in an opted-in development workarea, recall returns unreviewed memories, marked, and nothing leaves until a commit with none waiting.
Added a curator key profile that narrows what a key may do inside one workarea.
Added chat memory: origin.kind names each memory's source, and a person's chat workarea holds facts an agent writes from a conversation.
Added valid time: a memory may state when it is true, and recall hides what has ended.
Added on_similar: refuse, which turns away a write that repeats a readable memory.
Changed the secret scanner to the oml-scan/1 rule set and added oml admin rescan to report matches in stored memories.
Added the oml-lakewriter binary, which writes the Delta lake.
Added a production policy with service-level objectives and an error budget for a public server.

Upgrade notes: Migrations 0026 to 0031 run at upgrade.

0.5.8

Released 2026-11-05.

Added memory sources: a repository, commit, file, part and a fingerprint of that part's text, shown to the reviewer and signed.
Added recall and listing filters by repository and folder.
Added a hit marker that says when a memory's source changed or went away.
Added oml sync with --dry-run, --check and --exclude to load a repository's markdown documents in batches one person reviews.
Added oml anchor, which prints the anchor of one part of a file.
Changed replacement: a write names the version it read (expected_version), and a stale one is refused.

Upgrade notes: Restart agent sessions after the upgrade. Migration 0025 runs at upgrade.

0.5.7

Released 2026-11-05.

Added the optional searches bm25-sparse and sparse, which also find memories by related words.
Measured bm25-sparse at 0.730 nDCG@10 against 0.685 for the default (SciFact, 2026-11-05, 5,183 memories).
Added recall telemetry kept 30 days, with oml usage to read events and replay them against other searches.
Added bulk review: oml review list and approve or reject a chosen set, each memory its own signed verdict.

Upgrade notes: The server refuses to start when a configured sparse search lacks its model files. Migrations 0022 to 0024 run at upgrade.

0.5.6

Released 2026-11-05.

Changed recall to read an index: p95 25 ms with about 100,000 readable memories, measured at the database, against 485 ms in 0.5.5.
Added the default search bm25-postings, which says when it left out a very common word.
Added the optional reranker bm25-rerank, off until an operator places the model files.
Changed oml doctor to check the index and the reranker.

Upgrade notes: The first start builds the index and holds writes, at about 0.4 s per 1,000 memories.

0.5.5

Released 2026-11-05.

Changed recall to match any of a memory's words, parts of a code name and word forms, with rarer words ranked higher.
Changed the default search to bm25, and each hit names the words it matched.
Changed search words to be stored at write time: about 40 times faster on a 5,000-memory benchmark.
Added bm25-trigram for misspellings, which an administrator can make the default without a restart.
Added suggestions for a word that matched nothing, drawn from each workarea's own words.

Upgrade notes: The first start rewrites every stored memory once.

0.5.4

Released 2026-11-04.

Fixed the upgrade from 0.5.1 and earlier, which 0.5.3 broke on databases whose top workarea an early server created.

Upgrade notes: Do not install 0.5.3 over a 0.5.1 database. See upgrades.

0.5.3

Released 2026-11-04.

Published the content of 0.5.2.
Paused the macOS command-line builds. On a Mac, build oml from source.

0.5.2

Released 2026-11-04.

Added the workarea lifecycle: development, committed and validated, each step proposed by one identity and confirmed by another.
Added labeled links between two memories, such as supports and contradicts, each proposed and confirmed by different reviewers.
Added a brief for each workarea: reviewed memories an agent reads first at session start.
Changed oml doctor to name an empty brief and steps waiting for a second identity.

Upgrade notes: This tag was not published. 0.5.3 carries the same content.

0.5.1

Released 2026-11-04.

Added guardrails: reviewed rules each agent session loads at start, checked before matching tool calls.
Removed the eight 0.3.0 agent tool names and the old command-line verbs. Use oml_write, oml_read and oml_workarea.

0.5.0

Released 2026-11-04.

Added a workarea of one's own for each person, created at their first key.
Added a shared area above user roots, written only by curators an administrator chooses.
Added web pages for people: sign in with Google or GitHub, manage your keys and review your agents' memories.
Added an admin page to manage the allowlist, reviewers and curators and to read any memory, each read recorded.

Upgrade notes: Existing workareas and keys stay where they are.

0.4.1

Released 2026-11-04.

Added one log line for every request and agent tool call, kept at most 30 days by whatever stores them.
Added Prometheus metrics on a separate address and OpenTelemetry traces, both off unless set.

0.4.0

Released 2026-11-04.

Changed the agent interface to three task-shaped tools in place of eight.

Added oml login, oml setup claude-code and oml quickstart.

0.3.1

Released 2026-11-03.

Changed the server to run migrations as one database account and serve as another that owns nothing.
Added the oml command line for Linux, macOS and Windows, and the server for Intel and Arm Linux.

Upgrade notes: The server refuses to start when the two database accounts are the same.

0.3.0

Released 2026-10-31.

Added names for workareas, crews, keys and organizations, accepted wherever an id is.
Added crews as records of their own.

Added session-start context: an agent's recent work and the memories that match the project, within a budget.

0.2.1

Released 2026-10-31.

Added one command that issues an agent's key with search and write access and can write it to a private file.

0.2.0

Released 2026-10-31.

Added one key that writes and searches through granted workareas, where a denial always wins.
Added reads of your own held writes, budgeted search, standing instructions first, fetch by id, replace and retire.
Added eight agent tools and an event feed that shows each key only what it may see.
