 # @typeonce/effect-machine
 
+## 0.19.0
+
+### Minor Changes
+
+- b1a1f75: Make `Machine.encodeSnapshot` return a canonical JSON representation or fail
+  with `MachineSchemaEncodeError`. Encoded state values, completion outputs, and
+  history values are now typed as `Schema.Json`; rich schema values use their
+  canonical JSON codecs, while cycles and other non-JSON values fail at the
+  machine boundary instead of causing a later serialization crash.
+  Declared `Schema.Void` and `Schema.Undefined` completion outputs now use their
+  canonical `null` encoding; an omitted output is reserved for final states that
+  do not declare an output schema.
+
+  `ClusterMachine.make` now requires JSON-encoded state, completion-output, and
+  public input-event schemas. Keep process-local capabilities in services,
+  adapters, or internal events, and give transported values an explicit JSON
+  codec. Cluster snapshot encoding failures are reported as
+  `SnapshotEncodeFailure` without advancing the checkpoint.
+
+  `MachineTest.observedGraph` continues to support process-local state. Its node
+  `encoded` field is now optional: portable snapshots retain their canonical JSON
+  form, while non-portable snapshots use local structural identity and omit it.
+  Snapshot encoding failures no longer appear in the operation's error channel.
+
+### Patch Changes
+
+- 928017e: Upgrade the exact Effect peer dependency and companion Effect packages to `4.0.0-rc.110`.
+- f4f9bdf: Document the nested configuration and callback APIs used by `Machine.states`, event protocols, `Machine.make`, `Definition.handle`, execution, transitions, and state invocation.
+
+  The documentation site now presents those core authoring APIs on a standalone guide-reference page while keeping module pages focused on public exports. Parameters remain grouped under their point of use with searchable signatures, lifecycle contexts, target semantics, defaults, source links, focused examples, and a complete nested page outline. Redundant configuration headings are omitted, and each parameter is presented as a named API block with its signature, description, and attached source link. Long signatures stay contained within their documentation blocks across responsive layouts.
