 # Changelog
 
+## 2026-03-02 - 10.1.5 - fix(monitoring)
+use a per-second ring buffer for DNS query metrics, improve DNS logging rate limiting and security event aggregation, and bump smartmta dependency
+
+- Replace unbounded query timestamp array with a fixed-size per-second Int32Array ring buffer (300s) to calculate queries-per-second with O(1) updates and bounded memory
+- Add incrementQueryRing and getQueryRingSum helpers to correctly zero stale slots and sum recent seconds
+- Change metrics cache interval from 200ms to 1000ms to better match dashboard polling and reduce update frequency
+- Refactor DNS adaptive logging to use per-second counters (dnsLogWindowSecond / dnsLogWindowCount) instead of timestamp arrays to avoid per-query array filtering and improve rate limiting accuracy; reset counters on flush
+- Security logger: avoid mutating source when sorting/filtering, and implement single-pass aggregation with optional time-window filtering for byLevel/byType/top lists
+- Bump dependency @push.rocks/smartmta from ^5.3.0 to ^5.3.1
+
+## 2026-03-02 - 10.1.4 - fix(no-changes)
+no changes detected; no version bump required
+
+- package version is 10.1.3
+- git diff contains no changes
+
+## 2026-03-02 - 10.1.3 - fix(deps)
+bump @api.global/typedrequest to ^3.2.7
+
+- Updated @api.global/typedrequest from ^3.2.6 to ^3.2.7 in package.json
+- Dependency patch bump only — no source code changes detected
+- Current package version 10.1.2 -> recommended next version 10.1.3 (patch)
+
+## 2026-03-01 - 10.1.2 - fix(core)
+improve shutdown cleanup, socket/stream robustness, and memory/cache handling
+
+- Reset security singletons and CacheDb on shutdown to allow GC (SecurityLogger, ContentScanner, IPReputationChecker, CacheDb).
+- Add DNS socket 'error' handler and only destroy socket when not already destroyed to avoid uncaught exceptions.
+- Move pruning of dnsMetrics.queryTimestamps to a periodic interval to avoid O(n) work on every query.
+- Debounce IPReputationChecker cache saves (save timer + reset on instance reset) to reduce IO and prevent duplicate saves.
+- Fix virtualStream send timeout handling by keeping/clearing a timeout handle to avoid leaks and hung promises.
+- Add memory store eviction in StorageManager to cap entries (MAX_MEMORY_ENTRIES) and evict oldest entries when exceeded.
+- Add terminal-ready timeout in ops-view-logs to avoid blocking UI initialization if xterm CDN fails to initialize.
+- Bump dev dependency @types/node and push.rocks/smartstate versions.
+
+## 2026-02-27 - 10.1.1 - fix(ops-view-apitokens)
+replace lucide:refresh-cw with lucide:rotate-cw for Roll action icon
+
+- Updated ts_web/elements/ops-view-apitokens.ts: changed iconName in two locations to 'lucide:rotate-cw' for the Roll/Roll Token actions.
+- UI-only change — no functional or API behavior modified.
+- Current package version is 10.1.0; recommended patch bump to 10.1.1. 
+
 ## 2026-02-27 - 10.1.0 - feat(api-tokens)
 add ability to roll (regenerate) API token secrets and UI to display the newly generated token once
