+# Release Notes for v0.5.0 (Candidate Release)
+
+## Highlights
+
+- Knowledge Base supports configuring text chunking setting
+- Add Bedrock Converse support
+- Improve Chat Engine settings
+  - Support selecting multiple Knowledge Bases
+  - Support switches to control whether to use Further Questions and Rewrite Question feature
+  - Support more options to control the vector search retrieval
+- Support updating LLM / Embedding Model / Reranker Model configuration
+- Support reindex single document
+
+## Improvements
+
+- Modify the default `context_window` of Ollama LLM provider to 4096 tokens. (Too large context window for local LLM may cost more GPU memory, too small context window may cause insufficient context tokens error)
+
+## Breaking Changes
+
+- The new version uses [RichPromptTemplate](https://docs.llamaindex.ai/en/stable/examples/prompts/rich_prompt_template_features/) to manage prompt templates, after upgrading, you need to modify the old placeholders in the **Answer Question** prompt template like:
+  - `<<context_str>>` -> `{{context_str}}`
+  - `<<query_str>>` -> `{{query_str}}`
