+## [0.8.23] - 2026-03-12
+
+### Fixed — Node 24+ ESM Import Crash
+- **Node 24+ `squad init` crash fix (#XXX)** — v0.8.23 resolves `ERR_MODULE_NOT_FOUND: Cannot find module 'vscode-jsonrpc/node'` crash that occurs on Node.js 24+ and GitHub Codespaces. Root cause: upstream ESM import issue in `@github/copilot-sdk`. Two-layer defense implemented:
+  - **Lazy imports** — Commands `init`, `build`, `link`, `migrate` no longer eagerly load copilot-sdk at startup
+  - **Postinstall patch** — Automatically fixes broken ESM import at install time
+  - Side benefit: Faster CLI startup for non-session commands
+
+### Added — Squad RC Documentation
+- Comprehensive guide for `squad rc` (Remote Control) covering:
+  - ACP (Azure Communication Platform) passthrough architecture
+  - 7-layer security model for session isolation and encryption
+  - Mobile keyboard shortcuts and accessibility features
+  - Troubleshooting guide for common connection issues
+
+### By the Numbers
+- 2 issues closed
+- 3 PRs merged
+- 3,811 tests passing (3,840 total, 0 logic failures)
+- 1 critical crash fix (Node 24+ compatibility)

+## Node 24+ Compatibility Fix
+
+v0.8.23 fixes a critical crash when running `squad init` on Node.js 24+ (including GitHub Codespaces):
+
+```
+Error [ERR_MODULE_NOT_FOUND]: Cannot find module 'vscode-jsonrpc/node'
+```
+
+The root cause was an upstream ESM import issue in `@github/copilot-sdk`. Squad now uses a two-layer defense:
+- **Lazy imports** — commands like `init`, `build`, `link`, and `migrate` no longer eagerly load copilot-sdk
+- **Postinstall patch** — automatically fixes the broken import at install time
+
+This also means CLI startup is faster for non-session commands.
