+# Durable Workflow Server 3.11.0 (native)
+
+Server 3.11.0 reuses completed plain timers when redriving a run that failed at
+an activity. The successor resumes the failed activity with the original timer
+clock. Its immutable images are
+`durableworkflow/server:3.11.0` and `ghcr.io/durable-workflow/server:3.11.0`;
+the published Compose default selects 3.11.0. Rolling aliases move separately
+after the published producer and applicable SDK replay qualification.
+
+## Fired timer reuse
+
+A plain timer before the failed activity must have exactly one ordered
+`TimerScheduled` / `TimerFired` pair at a unique step, with matching source timer
+identity. The successor records the pair under one new shared timer ID. It
+creates no timer row or timer task and does not wait for the timer again.
+
+The reused `TimerFired` records the immediate predecessor in
+`reused_from_run_id`. Its `reused_recorded_at` preserves the timer's original
+execution time, including after another redrive. The original source history
+remains unchanged. Earlier activity and marker steps keep their existing
+reuse rules, and only the failed activity is resumed.
+
+Redrive replay timestamps now retain nonzero fractional precision for reused
+activities, markers and fired timers. The initial replay anchor retains the
+persisted source run start with full precision. Repeated redrives preserve
+already-recorded reuse timestamps as recorded. This change cannot reconstruct
+fractions omitted by an earlier producer. Deadline formatting is unchanged.
+
+Scope, group, cancellation-cleanup, condition and signal-timeout timers remain
+outside this plain-timer slice and refuse as `unsupported_timer`. Incomplete,
+reversed, duplicate or mismatched timer pairs refuse as `incomplete_timer_step`.
+Step collisions, gaps and invalid failure boundaries retain their explicit
+refusals. Cancelled timers and other unsupported history remain refused.
+Describe and redrive use the same eligibility decision.
+
+## Upgrade and compatibility
+
+**From 3.10.x, no schema step is needed.** The physical schema remains SQLite 14,
+PostgreSQL and MariaDB 15, and MySQL 16. Follow the existing backup and upgrade
+guidance, pin the new image, and verify readiness, reported version and worker
+registration. Update API replicas consistently before relying on the expanded
+redrive eligibility; older replicas retain their earlier refusal rules.
+
+From 3.9.x or earlier, apply the applicable explicit schema steps in the
+[3.10 upgrade procedure](https://github.com/durable-workflow/server/releases/tag/3.10.0#upgrade-and-rollback).
+This release does not convert a PHP database at startup. The existing takeover
+runbook retains its exact historical version, backend and state limits.
+
+Worker protocol `1.20`, control-plane version `2`, codec and command shapes are
+unchanged. Existing command-key, completion-byte, storage-admission and
+unsupported service-upsert boundaries remain in force. This release does not
+add redrive support for signals, updates, child workflows or scoped/group timers.
+
+## Qualification and retained limits
+
+The actual PHP, Python and Rust Worker/cold-process timer-clock proof is tracked
+on [#980](https://github.com/durable-workflow/server/issues/980). Source controls
+alone do not establish those installed consumer outcomes. Producer source,
+backend/corpus, immutable publication, Compose, scan/provenance and exact
+published consumer evidence remain separately attributable. Core precision
+correction and reference-corpus follow-through retain their separate record in
+[Workflow #992](https://github.com/durable-workflow/workflow/issues/992).
+
+The MariaDB registration-timeout investigation
+[#1204](https://github.com/durable-workflow/server/issues/1204) remains separate.
+Cloud adoption, physical mapping and broader cancellation-policy qualification
+retain their existing limits. PHP Server 2.11.8 remains retired and unpatched; see the
+[retirement/security notice](../security/retired-php-server-2026-11-13.md).
