+## [2.13.0] - 2026-05-29
+
+### Added
+
+- `enable_system_trust_store` config flag to switch the shared SSL context to the OS trust store for corporate TLS / private CA setups
+
+### Changed
+
+- MCP HTTP transport now uses Vibe's shared SSL context so it honors `SSL_CERT_FILE` / `SSL_CERT_DIR` and the system trust store opt-in
+- API key onboarding and plan-upgrade CTAs now link to the new Mistral Vibe Code extensions page
+- Compaction summaries are now injected into the conversation instead of replacing it
+
+### Fixed
+
+- Crash during initialization
+- VS Code extension promo banner now sits at the top of the conversation instead of being pinned above the input
+
 ## [2.12.1] - 2026-05-27
 
 ### Fixed

@@ -425,6 +425,16 @@ Vibe supports multiple ways to configure your API keys:
 
 **Note**: The `.env` file is specifically for API keys and other provider credentials. General Vibe configuration should be done in `config.toml`.
 
+### TLS and Corporate Certificate Authorities
+
+By default, Vibe uses the bundled `certifi` certificate roots for outbound HTTPS requests. If your organization installs private certificate authorities in the operating system trust store, you can opt in to the system trust store in `config.toml`:
+
+```toml
+enable_system_trust_store = true
+```
+
+`SSL_CERT_FILE` and `SSL_CERT_DIR` are still supported and are loaded as additional trust anchors.
+
 ### Custom System Prompts
 
 You can create `AGENTS.md` files to add custom instructions. You can also replace the entire system prompt.
