 # @runfusion/fusion
 
+## 0.19.0
+
+### Minor Changes
+
+- 1e73863: Add first-class llama.cpp provider support with bundled extension wiring, dashboard status/auth routes, model filtering, and onboarding/settings UI for enabling llama-server models without manual `pi install` steps.
+- 496c000: Add `fn update` command to check for and install the latest version of Fusion.
+- df253a8: Cache merge verification by tree hash and boost test concurrency for in-review verification.
+
+### Patch Changes
+
+- d06475b: Harden the publish path against dockerode-class missing-dependency regressions (#33). Adds a generalized invariant test that walks `tsup.config.ts` and asserts every non-builtin `external` is either a runtime dep or in an explicit transitive-allowlist, plus a pre-publish smoke step in `pnpm release` that packs the public tarballs, installs them with plain `npm` into a clean temp dir, and invokes the bin — catching the dockerode-class bug (and others like missing `files` globs) before publish, since pnpm hoisting masks it in the workspace.
+- eeab870: Store generated memory insight artifacts under `.fusion/memory/` (`memory-insights.md`, `memory-audit.md`, and `memory-audit-state.json`) instead of top-level `.fusion/` files, with compatibility migration for existing legacy files.
+- d30f8a7: Allow the dashboard task-detail footer action to manually drive PR-first completion when `mergeStrategy` is `pull-request` and `autoMerge` is disabled.
+- 8483a5f: Make the settings modal fill the viewport on mobile and align section headings with form-group gutters for consistent spacing across each settings page.
+- df253a8: Cache per-package test results by content hash to skip unchanged packages across sequential merges.
+
+  `scripts/test-changed.mjs` now maintains a per-project cache at `.fusion/test-cache.json`. For each package in a changed-mode run, a SHA-256 is computed from the git blob SHAs of every tracked file in the package directory plus `pnpm-lock.yaml` and `tsconfig.base.json`. If the hash matches a cache entry younger than 7 days the package is excluded from the `pnpm --filter` invocation and tests are skipped. After a successful run the passing hashes are written atomically. Cache lookups are bypassed when `FUSION_TEST_NO_CACHE=1` or `--no-cache` is passed, and never applied to full-suite runs. A new `FUSION_TEST_WORKSPACE_CONCURRENCY` env var controls `--workspace-concurrency` (default `2`).
