+- Switched from Ollama's OpenAI-compatible embedding endpoint to their "native" one (PR [#115](https://github.com/philippgille/chromem-go/pull/115) by [@hungrymonkey](https://github.com/hungrymonkey))
+  - This requires at least Ollama [v0.3.4](https://github.com/ollama/ollama/releases/tag/v0.3.4) from 2024-08-06.
