 # Changelog

+## 2025-02-03 - 3.0.57 - fix(updateManager)
+Refine cache management for service worker updates.
+
+- Ensured cache is forcibly updated if older than defined maximum age.
+- Implemented interval checks and forced updates for cache staleness.
+- Updated version information and cache timestamps upon forced updates or validations.
+
+## 2025-02-03 - 3.0.56 - fix(cachemanager)
+Adjust cache control headers and fix redundant code
+
+- Remove duplicate assetbroker URLs in the cache evaluation logic.
+- Update cache control headers to improve caching behavior.
+- Increase the timeout for fetch operations to improve compatibility.
+
+## 2025-01-28 - 3.0.55 - fix(server)
+Fix response content manipulation for HTML files with injectReload
+
+- Moved fileString declaration inside HTML file handling block to prevent unnecessary string conversion for non-HTML files.
+- Corrected responseContent assignment to ensure modified HTML strings are converted back to Buffer format.
+
+## 2025-01-28 - 3.0.54 - fix(servertools)
+Fixed an issue with compression results handling in HandlerStatic where content was always being written even if not compressed.
+
+- Corrected the double writing of response in HandlerStatic.
+- Ensured that file buffers are only conditionally written based on compression availability.
+
+## 2024-12-26 - 3.0.53 - fix(infohtml)
+Remove Sentry script and logo from HTML template
+
+- Removed Sentry script from the HTML template.
+- Removed Lossless GmbH logo and contact info.
