 - LINE/Voice transcription: classify M4A voice media as `audio/mp4` (not `video/mp4`) by checking the MPEG-4 `ftyp` major brand (`M4A ` / `M4B `), restoring voice transcription for LINE voice messages. Landed from contributor PR #31151 by @scoootscooob. Thanks @scoootscooob.
 - Cron/Delivery mode none: send explicit `delivery: { mode: "none" }` from cron editor for both add and update flows so previous announce delivery is actually cleared. Landed from contributor PR #31145 by @byungsker. Thanks @byungsker.
 - Control UI/Debug log layout: render Debug Event Log payloads at full width to prevent payload JSON from being squeezed into a narrow side column. Landed from contributor PR #30978 by @stozo04. Thanks @stozo04.
+- Cron editor viewport: make the sticky cron edit form independently scrollable with viewport-bounded height so lower fields/actions are reachable on shorter screens. Landed from contributor PR #31133 by @Sid-Qin. Thanks @Sid-Qin.
 - Agents/Thinking fallback: when providers reject unsupported thinking levels without enumerating alternatives, retry with `think=off` to avoid hard failure during model/provider fallback chains. Landed from contributor PR #31002 by @yfge. Thanks @yfge.
 - Agents/Failover reason classification: avoid false rate-limit classification from incidental `tpm` substrings by matching TPM as a standalone token/phrase and keeping auth-context errors on the auth path. Landed from contributor PR #31007 by @HOYALIM. Thanks @HOYALIM.
 - Slack/Announce target account routing: enable session-backed announce-target lookup for Slack so multi-account announces resolve the correct `accountId` instead of defaulting to bot-token context. Landed from contributor PR #31028 by @taw0002. Thanks @taw0002.
