+### Added
+
+- 🖥️ **Use cptr as a model.** cptr, Open WebUI's standalone companion app, now exposes an OpenAI-compatible gateway with first-class Open WebUI support, so a one-click setup adds it as a connection and lets you drive its full agent loop (files, terminal, git, and web access on the machine it runs on) from chat as if it were just another model. [GitHub](https://github.com/open-webui/computer)
+- 🏷️ **More custom header variables.** Custom request headers now support "{{USER_MESSAGE_ID}}", "{{USER_MESSAGE_PARENT_ID}}", and "{{TASK}}", letting connected services tell apart real user messages from automated background requests like title, tag, and follow-up generation. [Commit](https://github.com/open-webui/open-webui/commit/f85cb27ef835aa76aff7de6176bf2159ba392061)
+- 🔄 **General improvements.** Various improvements were implemented across the application to enhance performance, stability, and security.

+### Changed
+
+- 🔀 **Native tool calling is now the default.** Every chat and model that had not explicitly chosen a tool-calling mode now runs Native, which relies on a model's built-in tool support, while the old behavior has been renamed "Legacy" and made the explicit opt-out; if your models depend on the previous approach you must switch them back to "Legacy" per chat, per model, or globally in your default model parameters to preserve their behavior.
