 # Changelog
 
-## master
+## [Unreleased]
+### Added
+- TIFF and BMP support.
+- `IMGPROXY_REPORT_DOWNLOADING_ERRORS` config. Setting it to `false` disables reporting of downloading errors.
+- SVG passthrough. When source image and requested format are SVG, image will be returned without changes.
+- `IMGPROXY_USE_GCS` config. When it set to true and `IMGPROXY_GCS_KEY` is not set, imgproxy tries to use Application Default Credentials to get access to GCS bucket.
 
+### Changed
 - Reimplemented and more errors-tolerant image size parsing;
-- TIFF and BMP support;
-- Using Application Default Credentials when `IMGPROXY_USE_GCS` is set to `true` but `IMGPROXY_GCS_KEY` is not set.
-  **Note:** If you use `IMGPROXY_GCS_KEY`, it's recommended to set `IMGPROXY_USE_GCS` to `true` since it may be required by future versions to enable GCS support;
-- Setting `IMGPROXY_REPORT_DOWNLOADING_ERRORS` to `false` disables reporting of downloading errors;
-- SVG passthrough. When source image and requested format are SVG, image will be returned without changes;
 - Log only modified processing options;
+
+### Fixed
 - Fixed sharpening+watermarking;
 - Fixed path parsing when no options is provided and image URL is Base64 encoded.
 
-## v2.5.0
+### Deprecated
