@@ -34,6 +34,7 @@ Docs: https://docs.openclaw.ai
 - Security/Hooks: harden webhook and device token verification with shared constant-time secret comparison, and add per-client auth-failure throttling for hook endpoints (`429` + `Retry-After`). Thanks @akhmittra.
 - Security/Browser: require auth for loopback browser control HTTP routes, auto-generate `gateway.auth.token` when browser control starts without auth, and add a security-audit check for unauthenticated browser control. Thanks @tcusolle.
 - Sessions/Gateway: harden transcript path resolution and reject unsafe session IDs/file paths so session operations stay within agent sessions directories. Thanks @akhmittra.
+- Sessions: preserve `verboseLevel`, `thinkingLevel`/`reasoningLevel`, and `ttsAuto` overrides across `/new` and `/reset` session resets. (#10787) Thanks @mcaxtr.
 - Gateway: raise WS payload/buffer limits so 5,000,000-byte image attachments work reliably. (#14486) Thanks @0xRaini.
 - Logging/CLI: use local timezone timestamps for console prefixing, and include `±HH:MM` offsets when using `openclaw logs --local-time` to avoid ambiguity. (#14771) Thanks @0xRaini.
 - Gateway: drain active turns before restart to prevent message loss. (#13931) Thanks @0xRaini.
