 The goal is to emulate the [Google AI Python SDK](https://github.com/google/generative-ai-python) but in Rust.
 
-The initial focus will be on the [newer Gemini models](https://blog.google/technology/ai/google-gemini-ai/), but the more stable and mature models will hopefully also be supported soon.

 ## Work status
 
-## Potentially Breaking Changes
-
-Version `0.3.0` may lead to breaking changes. This version adds in some `beta` features and I have now added a feature flag to enable these.
-
 ```
-google-generative-ai-rs = { version = "0.3.0", features = ["beta"] }
+google-generative-ai-rs = { version = "0.3.4", features = ["beta"] }
 ```
 
 Using the `beta` feature will enable the following:
 
 - `gemini-1.5-pro-latest`
+- `gemini-1.0-pro`
+- `gemini-1.5-pro-latest")`
+- `gemini-1.5-flash")`
+- `"gemini-1.5-flash-8b")`
+- `gemini-2.0-flash-exp")`
+- or custom `Model::Custom(name)`
 - system instructions
 - `json_mode`
 
+Note: `gemini-1.0-pro` is deprecated and will be unavailable from 15th February 2025.
+
 I do my best to release working code.
 
 Status today is: *"Happy path for both public and Vertex AI endpoints work for Gemini."*
