+## [0.1.1] - 2025-12-23
+
+### Changed
+
+- Updated Avalonia packages from 11.3.9 to 11.3.10 (required by Flowery.NET).
+- Updated System.Text.Json from 10.0.0 to 10.0.1.
+- Updated App_Title in all localization files to include ".NET" suffix.
+
+### Fixed
+
+- Fixed deprecation warning in `AsciiArtGenerator.cs` by replacing `SKFilterQuality` with `SKSamplingOptions`.
+- Fixed CA1416 platform compatibility warnings in `ImageConverter.cs` by adding `[SupportedOSPlatform("windows")]` attribute.
+- Fixed Scientific Calculator: Enter key now always triggers calculation instead of re-activating the last clicked button.
+- Fixed Scientific Calculator: Unary minus was being ignored, causing negative results to become positive in subsequent calculations (e.g., `-1522 + 2000` incorrectly returned `3517` instead of `478`).
+- App title in all localizations now state ".NET" at the end
