 # CHANGELOG.md
 
-## v0.39.1 (2025-11-08)
- - More precise server timing tracking to debug performance issues
- - Fix missing server timing header in some cases
- - Implement nice error messages for some header-related errors such as invalid header values.
- - `compress_responses` is now set to `false` by default in the configuration.
-  - When response compression is enabled, additional buffering is needed. Users reported a better experience with pages that load more progressively, reducing the time before the pages' shell is rendered.
-  - When SQLPage is deployed behind a reverse proxy, compressing responses between sqlpage and the proxy is wasteful.
- - In the table component, allow simple objects in custom_actions instead of requiring arrays of objects.
- - Fatser icon loading. Previously, even a page containing a single icon required downloading and parsing a ~2MB file. This resulted in a delay where pages initially appeared with a blank space before icons appeared. Icons are now inlined inside pages and appear instantaneously.
- - Updated tabler icons to 3.35
- - Fix inaccurate ODBC warnings
- - Added support for Microsoft SQL Server named instances: `mssql://user:pass@localhost/db?instance_name=xxx`
- - Added a detailed [performance guide](https://sql-page.com/blog?post=Performance+Guide) to the docs.

 ## v0.39.0 (2025-10-28)
  - Ability to execute sql for URL paths with another extension. If you create sitemap.xml.sql, it will be executed for example.com/sitemap.xml
