* 0.9.8.5 2025-06-11

** Breaking changes

- ~gptel-org-branching-context~ is now a global variable.  It was
  buffer-local by default in past releases.

- The following models have been removed from the default ChatGPT backend:
  - ~o1-preview~: use ~o1~ instead.
  - ~gpt-4-turbo-preview~: use ~gpt-4o~ or ~gpt-4-turbo~ instead.
  - ~gpt-4-32k~, ~gpt-4-0125-preview~ and ~gpt-4-1106-preview~: use
    ~gpt-4o~ or ~gpt-4~ instead.
  Alternatively, you can add these models back to the backend in your
  personal configuration:
  #+begin_src emacs-lisp
  (push 'gpt-4-turbo-preview
        (gptel-backend-models (gptel-get-backend "ChatGPT")))
  #+end_src

- Only relevant if you use ~gptel-request~ in your elisp code,
  /interactive gptel usage is unaffected/: ~gptel-request~ now takes a
  new, optional =:transforms= argument.  Any prompt modifications
  (like adding context to requests) must now be specified via this
  argument.  See the definition of ~gptel-send~ for an example.

** New models and backends

- Add support for ~gpt-4.1~, ~gpt-4.1-mini~, ~gpt-4.1-nano~, ~o3~ and
  ~o4-mini~.

- Add support for ~gemini-2.5-pro-exp-03-25~,
  ~gemini-2.5-flash-preview-04-17~, ~gemini-2.5-pro-preview-05-06~ and
  ~gemini-2.5-pro-preview-06-05~.

- Add support for ~claude-sonnet-4-20250514~ and
  ~claude-opus-4-20250514~.

- Add support for AWS Bedrock models.  You can create an AWS Bedrock
  gptel backend with ~gptel-make-bedrock~, which see.  Please note:
  AWS Bedrock support requires Curl 8.5.0 or higher.

- You can now create an xAI backend with ~gptel-make-xai~, which see.
  (xAI was supported before but the model configuration is now handled
  for you by this function.)

- Add support for GitHub Copilot Chat.  See the README and
  ~gptel-make-gh-copilot~.  Please note: this is only the chat
  component of GitHub Copilot.  Copilot's ~completion-at-point~
  (tab-completion) functionality is not supported by gptel.

- Add support for Sambanova.  This is an OpenAI-compatible API so you
  can create a backend with ~gptel-make-openai~, see the README for
  details.

- Add support for Mistral Le Chat.  This is an an OpenAI-compatible
  API so you can create a backend with ~gptel-make-openai~, see the
  README for details.

** New features and UI changes

- gptel now supports handling reasoning/thinking blocks in responses
  from Gemini models.  This is controlled by
  ~gptel-include-reasoning~, in the same way that it handles other
  APIs.

- The new option ~gptel-curl-extra-args~ can be used to specify extra
  arguments to the Curl command used for the request.  This is the
  global version of the gptel-backend-specific ~:curl-args~ slot,
  which can be used to specify Curl arguments when using a specific
  backend.

- Tools now run in the buffer from which the request originates.  This
  can be significant when tools read or manipulate Emacs' state.

- gptel can access MCP server tools by integrating with the mcp.el
  package, which is at https://github.com/lizqwerscott/mcp.el.
  (mcp.el is available on MELPA.)  To help with the integration, two
  new commands are provided: ~gptel-mcp-connect~ and
  ~gptel-mcp-disconnect~.  You can use these to start MCP servers
  selectively and add tools to gptel.  These commands are also
  available from gptel's tools menu.
  
  These commands are currently not autoloaded by gptel.  To access
  them, require the ~gptel-integrations~ feature.

- You can now define "presets", which are a bundle of gptel options,
  such as the backend, model, system message, included tools,
  temperature and so on.  This set of options can be applied together,
  making it easy to switch between different tasks using gptel.  From
  gptel's transient menu, you can save the current configuration as a
  preset or apply another one.  Presets can be applied globally,
  buffer-locally or for the next request only.  To persist presets
  across Emacs sessions, define presets in your configuration using
  ~gptel-make-preset~.
