 ### Added
 - Added support for `aigenerate` with Anthropic API. Preset model aliases are `claudeo`, `claudes`, and `claudeh`, for Claude 3 Opus, Sonnet, and Haiku, respectively.
 - Enabled the GoogleGenAI extension since `GoogleGenAI.jl` is now officially registered. You can use `aigenerate` by setting the model to `gemini` and providing the `GOOGLE_API_KEY` environment variable.
+- Added utilities to make preparation of finetuning datasets easier. You can now export your conversations in JSONL format with ShareGPT formatting (eg, for Axolotl). See `?PT.save_conversations` for more information.
 
 ### Fixed
 
 ## [0.16.1]
 
 ### Fixed
-- Fixed a bug where `set_node_style!` was not accepting any Stylers expect for the vanilla `Styler`.
