# Changelog

All notable changes to Raster Blaster will be documented in this
file.

## [2.0.0] - 2025-12-09

### Added

- **Background processing**: All GDAL operations now run in a
background thread using QgsTask, keeping QGIS fully responsive during
processing
- **Progress tracking**: Real-time progress bar shows processing
status
- **User-selectable CRS**: Full CRS selector widget replaces the
hardcoded EPSG:3857 - choose any projection
- **Persistent settings**: Plugin remembers your preferences between
sessions:
  - Last used directory
  - Compression method
  - Resampling method  
  - Transformation type
  - Target CRS
  - JPEG quality
  - Auto-load preference
- **Auto-load results**: Option to automatically add processed rasters
to the map
- **JPEG quality control**: Adjustable quality slider (1-100%) when
using JPEG compression
- **GCP validation warnings**:
  - Checks GCP count against transformation requirements (e.g.,
Polynomial order 2 needs 6+ GCPs)
  - Warns if GCPs are clustered in one area of the image
  - Warns if GCPs are arranged in a nearly straight line
- **Overwrite protection**: Prompts for confirmation before
overwriting existing output files
- **Auto-fill output path**: Selecting an input image automatically
fills the output field with a suggested filename
- **Additional compression options**: Added ZSTD and NONE to
compression choices
- **Better encoding support**: Points file parser tries UTF-8,
Windows-1252, and Latin-1 encodings

### Changed

- **Menu location**: Moved from `Plugins → Raster Blaster` to `Raster
→ Raster Blaster` for better discoverability
- **Dialog layout**: Reorganized with grouped sections (Files,
Options) for cleaner interface
- **Error messages**: More informative error messages and logging

### Fixed

- **UI freeze**: Processing no longer freezes QGIS interface
- **File overwrite errors**: Properly handles existing output files
instead of failing with GDAL error
