 ## Per-version migration notes
 
+### Chart 1.7.0 / Server 3.9.0 (native)
+
+**Every backend needs an explicit native schema upgrade.** Server 3.9.0 adds
+one native-only table, `dw_command_intents`, created empty. It rewrites no
+existing rows:
+
+| Backend | Schema |
+| --- | --- |
+| SQLite | 12 to 13 |
+| PostgreSQL | 13 to 14 |
+| MariaDB | 13 to 14 |
+| MySQL | 14 to 15 |
+
+1. Scale the Server to zero, including every replica sharing the database.
+2. Back up the database and external payload storage.
+3. Run `helm upgrade` with `native.schemaUpgrade.enabled=true` (or the manual
+   schema-upgrade Job in the chart README) so the 3.9.0 image runs
+   `schema-upgrade` once.
+4. Scale every Server back up on 3.9.0 and confirm readiness and worker
+   registration.
+
+Rolling back to 3.8.x requires restoring the backup taken in step 2: 3.8.0
+refuses the upgraded database with `native_schema_newer_than_binary`.
+Started on the earlier schema, 3.9.0 refuses with
+`native_schema_upgrade_required`. On MySQL and MariaDB an interrupted
+upgrade resumes when `schema-upgrade` is run again; SQLite and PostgreSQL
+upgrade in one transaction.
+
+From an earlier release, the same command applies every earlier step. On
+MySQL from Server 3.6.x or earlier this includes the Chart 1.5.0 JSON rebuild
+below, with its downtime of about 2 minutes per million history rows.
+
+**Behavior changes:**
+
+- A signal or update `request_id` is a durable command key. The same key
+  with different input returns `409 request_id_conflict` with zero writes.
+  Do not retry that 409 unchanged. Use the original input to recover the
+  receipt, or a new key for a new command. This differs from PHP 2.x.
+- A run's own complete, fail or continue-as-new now cancels its open
+  activities and timers before its terminal event. A workflow that needs a
+  select loser's effect must await it before returning. Workers must handle
+  final `run_closed` refusals; sdk-php 3.17.0, sdk-python 2.17.0 and sdk-rust
+  4.15.0 include the matching replay handling.
+- Commands with names longer than their database columns now get a typed
+  `422` before any write, including on SQLite, which previously stored them.
+
+Native also honors `DW_STORAGE_ADMISSION_FILE`,
+`DW_STORAGE_ADMISSION_SOURCE` and `DW_STORAGE_ADMISSION_MAX_AGE_SECONDS` when
+configured. Draining refuses new work while existing leases can finish;
+fenced or unavailable observations permit only reads. Completion uploads
+during draining remain unavailable, so workers hold their results and retry
+after pressure clears. See the
+[storage-admission contract](../../../../docs/storage-admission.md#native-server)
+and [Server 3.9.0 release notes](../../../../docs/releases/3.9.0.md).
