+#### API changes
+
+- Update the /ask endpoint to use the new ChatGPT API and the newly released `gpt-3.5-turbo` model. This has resulted in a pricing decrease and more questions included in the free tier.
+- Fixed error when a lot of nested clauses would cause the /ask endpoint to return 500 errors
+- Corrected the license of the published OpenAPI spec to Apache-2
+
+#### UI changes
+
+- Fixed pasting behaviour when a cell is in edit more. It used to overwrite the whole cell, now it correctly appends to the existing text.
+- Several fixes around column constraints:
+  - Users can set default value without setting `notNull: true`
+  - Users can enter invalid constraint combinations but are presented with a clear error about what they did wrong.
+  - Switching column type resets unique, `notNull` and default value to an allowed value if it's unsupported.
+- Prevent two table cells from being selected in some scenarios. There was a bug when data had changed in the grid and you let your browser tab lose and regain focus.
+- Fixed copy paste null string values in table
+- More minor cell editing bug fixes
+- Small design issues cleanup across the app
+  - right input padding for table inputs
+  - clickable table headers in the schema page
+  - scrollable branch list

+### What's new
+
+- We have added a way to disable search on your database. This is a good way to reduce cost if you aren't using any of the search functionality (search, aggregation, vector search). By disabling search, you won't be paying for Elasticsearch storage. You can find the toggle in the database settings. Don't worry though, search is still included in the free tier and enabled by default.
+

+
+- The schema edit view within the UI received a visual upgrade. It should be easier to view the requirements for each column at a glance.
+

+
+- In preparation for our upcoming releases, we have re-structured our docs to make it easier to find what you're looking for. Please let us know if you have any feedback! Also quick reminder: the search bar in the docs works really well (because it's based on Xata).
+- We've added `beta` and `alpha` tags to features that are not yet generally available. At a high level you can think of `alpha` as "only available to a select group of users" and `beta` as "available to all users, but not yet stable".
+- Updated the error messages when trying to use the SDK directly from the browser to point to a particular docs URL.
