 # Changelog
 
+## 2026-01-12 - 3.36.0 - feat(dees-chart-log)
+add xterm search addon support and enhance chart log demo with structured/raw (Docker-like) logs and themeable styles
+
+- Add IXtermSearchAddon and IXtermSearchAddonBundle types and integrate xterm-addon-search loading in DeesServiceLibLoader with caching and preload support
+- Expose new types in services index and add xtermAddonSearch version to CDN_VERSIONS
+- Enhance dees-chart-log demo: separate structured and raw (docker) log panels, add Docker/ANSI log templates, start/stop controls for each simulation, and raw log writing
+- Switch demo styling to cssManager theme-aware CSS, and import css helpers from dees-element
+- Add many .playwright-mcp PNG assets used by demos/tests
+
+## 2026-01-12 - 3.35.1 - fix(dees-statsgrid)
+center CPU core bars when they occupy less than ~66% of the tile and switch bar fills to absolute positioning for correct alignment and smoother transitions
+
+- Add .cpu-cores-bars.centered CSS rule to horizontally center the bars when appropriate.
+- Compute shouldCenter by estimating max bars width (cores * 24px + gaps) and comparing to estimated tile content width (accounts for columnSpan, minTileWidth, gap and ~32px padding), using a 66.6% threshold.
+- Change .cpu-core-bar-container to position: relative and .cpu-core-bar-fill to position: absolute (bottom:0; left:0; right:0) to ensure correct vertical alignment and smoother height transitions.
+
 ## 2026-01-12 - 3.35.0 - feat(dees-statsgrid)
 add cpuCores tile type with column spanning, rendering, demo and docs
