Upgrade guide

How to upgrade between sessionwiki releases. Most releases are drop-in (pip install -U sessionwiki or brew upgrade sessionwiki) — this page documents the exceptions: schema migrations, config changes, and behaviour flips that affect what happens on your next sync.

The canonical per-release detail is CHANGELOG.md — this guide focuses on "what might break".

v1.3.0 — consolidated 1.2.x patch roll-up

Released: 2026-04-26.

Summary

Drop-in upgrade from any 1.2.x. v1.3.0 consolidates 38 in-tree patch versions (1.2.1 → 1.2.38) under one minor release tag — no breaking API changes, no schema migrations, no config changes.

pip install -U sessionwiki   # → 1.3.0
sessionwiki --version             # → 1.3.0

What's in it

The full per-fix detail is preserved under the [1.2.x] entries in CHANGELOG.md. Two themes:

Opus 4.7 deep code-review backlog (#403, ~26 issues) — every correctness, perf, and observability finding got a one-issue-one-PR fix. Headliners: is_subagent strict path check (#406), derive_session_slug UUID-prefix collision (#424), tilde-fence counting in _close_open_fence (#419), wiki_query ranking length normalisation (#418), wiki_search cap (#413), per-vault synth state (#420), --force sync persisting _meta/_counters (#426), subprocess claude_path resolved via shutil.which (#421).
Performance + features — DuplicateDetection lint rule rewritten with bucket+fingerprint+SequenceMatcher (1s vs minutes on 500 pages, #412), perf-budget test suite (-m slow, #429), md_to_plain_text cache (#417), auto-seeded project stubs pre-populated from session metadata (#425), 2 new lint rules (frontmatter_count_consistency, tools_consistency, #378), wiki-all slash command, _context.md folder convention (#60).

Breaking — none

Same CLI surface, same config schema, same on-disk state format. The only thing that changed is that the next plain sync after a forced re-sync will now correctly identify already-processed files as unchanged (was: re-processed every time, #426).

Schema migrations — none

State files written by 1.2.x are read verbatim by 1.3.0.

v1.2.0 — first stable on the 1.x line

Released: 2026-04-25.

Install changes

PyPI distribution name — upstream llmwiki was published as llm-notebook because llmwiki was taken on PyPI. sessionwiki uses one name everywhere (distribution, module, CLI): ```bash pip install sessionwiki # upstream: pip install llm-notebook sessionwiki --version # upstream CLI: llmwiki --version python3 -c "import sessionwiki" # still works (import name unchanged)


### Removed CLI subcommands

The CLI was slimmed in #362. If you scripted any of these, replace as
noted:

- `sessionwiki schedule` — removed. Schedule `sessionwiki sync` directly via
your OS's job runner (launchd / systemd / Task Scheduler).
- `sessionwiki install-skills` — removed. Manually copy
`.claude/commands/wiki-*.md` into `~/.claude/commands/` for global
availability.
- `sessionwiki check-links` — removed. Use the GitHub Actions link-check
workflow instead.
- `sessionwiki watch`, `sessionwiki manifest`, `sessionwiki link-obsidian`,
`sessionwiki export-obsidian`, `sessionwiki export-marp`, `sessionwiki export-qmd`,
`sessionwiki eval` — also removed.
- `sessionwiki export marp` is the new path for Marp slide export.

### Removed adapters

`jira_adapter`, `meeting`, `pdf` were removed in #363. If you depended
on any of them, pin v1.1.0-rc8 until you migrate.

### Demo data correctness

`user_messages` / `tool_calls` counts on the 8 demo session files were
2–10× higher than the body actually contained. The values are now
recomputed from body content. Two new lint rules (`#16
frontmatter_count_consistency`, `#17 tools_consistency`) prevent
regression.

### `sync --force` no longer drops colliding sessions

If you ran `sync --force` against a corpus where two sources had the
same canonical filename (rare but real on large corpora), one of them
was silently overwritten. Fix: per-run filename tracking now
disambiguates regardless of `--force`. Affected ~200 of 495 sessions
on a real corpus we tested.

### New: `sessionwiki all`

One-shot pipeline runner for CI:

```bash
sessionwiki all                  # build → graph → export → lint
sessionwiki all --strict         # exit 2 on any lint warning

Schema migrations

None. JSON sibling files now correctly emit int and bool types for user_messages / tool_calls / is_subagent (were strings); any downstream that string-compared is_subagent == "false" now needs is_subagent is False.

v1.1.0-rc5

Released: 2026-04-21.

New behaviour

Session transcripts strip project-local file refs. Anchors pointing at tasks.md, user_profile.md, settings.gradle.kts, .kiro/…, /Users/…, etc. are unwrapped into inline <span class="session-ref dead-link"> — the filename stays visible but the anchor doesn't 404. No action required.
README.md and CONTRIBUTING.md now compile as site pages. site/README.html and site/CONTRIBUTING.html ship alongside changelog.html. Link rewriter routes to the compiled page instead of GitHub for these two files.
/wiki-synthesize slash command — wraps sessionwiki synthesize with natural-language flags ("estimate cost", "dry run", "force"). Copy .claude/commands/wiki-synthesize.md into ~/.claude/commands/ for global availability. (sessionwiki install-skills was removed in v1.2.0; manual copy is the supported path.)
Dual-mode docs landing pages. docs/modes/api/ and docs/modes/agent/ exist as skeletons; the actual API / Agent backends ship with #315 / #316.

Schema migrations

None. Fully backwards-compatible with rc4 state files.

Breaking

None.

v1.1.0-rc4

Released: 2026-04-20.

New behaviour

Obsidian is opt-in now. Past versions fired the Obsidian adapter on every sync by default. If your workflow relied on that, add this to sessions_config.json:

```json { "obsidian": { "enabled": true } }


Context: [#326](https://github.com/Pratiyush/llm-wiki/issues/326).
Runs as of rc3; surfaced in `sessionwiki adapters` column `will_fire`.

- **Graph clicks respect compiled-site existence.** Nodes whose
corresponding page wasn't rendered to HTML show a tooltip instead
of opening a 404. No action needed — if you see the tooltip on
entity / concept / nav pages that's the new design.

- **Backlinks now propagate.** Run `sessionwiki backlinks` once to inject
managed `## Referenced by` sections into every linked-to page.
Idempotent, dry-runnable, prune-able:

```bash
sessionwiki backlinks --dry-run --verbose   # preview
sessionwiki backlinks                       # commit writes
sessionwiki backlinks --prune               # strip every block

Schema migrations

.llmwiki-state.json keys rewrite from absolute paths to <adapter>::<home-relative-path> on first load under rc3+. Migration is automatic and idempotent. If you moved your repo to a new machine, old state will be preserved verbatim — re-sync to reindex.
.llmwiki-quarantine.json is a new local file (gitignored). First appears when a convert error happens. Inspect with sessionwiki quarantine list.
Frontmatter tags: / topics: convention is lint-enforced (rule #14 tags_topics_convention) — projects use topics:, everything else uses tags:. Run sessionwiki tag convention to see violations. sessionwiki tag rename <old> <new> rewrites across every page.

Breaking — none

No breaking CLI or config changes. Every test pre-upgrade keeps passing post-upgrade.

v1.1.0-rc3

See the release notes for the full rc3 gap-sweep bundle. No migration required.

v1.0.0 → v1.1.0-rc1

Config: synthesis.backend now accepts "ollama" in addition to the default "dummy". See docs/reference/prompt-caching.md for the ollama setup.

wiki/candidates/ directory is new — created automatically by ingest when it sees a brand-new entity/concept. Triage with /wiki-candidates (renamed from /wiki-review in rc3).

Older versions

Pre-v1.0 milestones shipped under internal sprint tags. Upgrade from v0.9.x to v1.0.0 in one step — no intermediate migration required. If you're on a pre-0.9 build, start fresh: sessionwiki init in a new tree and re-run sync.
