 ## 🆕 Recent Updates
 
-### v2.2.14 - v2.2.18 - Version pinning, npm provenance, usage overage widgets, and Git lock avoidance
+### v2.2.14 - v2.2.19 - Version pinning, npm provenance, usage overage widgets, and Git lock avoidance
 
 - **📌 Version pinning support** - Added support for pinned global installs so Claude Code can keep running a specific ccstatusline version.
 - **🔐 npm provenance attestations** - Published packages now use trusted publishing provenance so users can verify where releases were built while avoiding long-lived npm publish tokens.
 - **🔄 Moving from auto-update installs** - If you currently use an auto-updating install, use the TUI uninstall option first, then reinstall to go through the version pinning flow. Your ccstatusline settings are preserved when uninstalling.
 - **💸 Extra usage widgets** - Added Extra Usage Utilization and Extra Usage Remaining widgets for monthly pay-as-you-go overage limits, with null rate-limit buckets handled as zero usage.
 - **🔒 Git lock avoidance** - Git helpers now pass `--no-optional-locks` so background status checks avoid creating `index.lock` races.
+- **🧱 Older Git compatibility** - Git widgets avoid newer command forms so repository status works on older Git installations.
+- **⚡ Persistent Git cache** - Git command output is cached under `~/.cache/ccstatusline/git-cache` with configurable TTL and `.git/HEAD`/`.git/index` mtime checks to reduce repeated subprocess work.
+- **🧭 Install flow polish** - Pinned global install is now the default install option, with clearer wording for install and migration flows.
+- **🪟 Hidden helper processes** - Runtime child processes set `windowsHide` so helper commands do not open extra windows on Windows.
+- **📏 Terminal width override** - `CCSTATUSLINE_WIDTH` can provide an explicit terminal width when automatic probing is unavailable.
