Release v1.1.0

CHANGELOG.md

@@ -5,6 +5,35 @@ All notable changes to this project will be documented in this file.
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [1.1.0] - 2026-01-25
+
+### Added
+
+- Shared HTML footer template injected into all pages.
+- Structured log file handler with rotation, append-only writes, and stats parsing support.
+- Upload size guard using `MAX_ASSET_SIZE_BYTES`.
+- Unit tests for core storage and rate limiting behavior.
+
+### Changed
+
+- Asset storage cleanup and capacity checks are now race-safe.
+- Stats aggregation now reads from the structured log file helper.
+
+## [1.0.1] - 2026-01-16
+
+### Fixed
+
+- Asset addition logging now displays immediately instead of being buffered (changed `print!` to `println!`).
+- Upload functionality blocked after first successful upload - users can now only upload once per page session.
+- Paste, drag & drop, and file selection disabled after successful upload to prevent confusion.
+- JavaScript syntax errors in event listener registration that prevented copy/paste functionality.
+- Removed nested and duplicated event listeners that caused unexpected behavior.
+
+### Changed
+
+- Added `uploadCompleted` flag to track upload state and prevent multiple uploads per session.
+- Reset button now properly clears the `uploadCompleted` flag to allow new uploads.
+
