Quiltflower 1.9.0
Quiltflower 1.9.0 brings dozens of bug fixes, new features, improved decompilation, and an improved way to interact with the Quiltflower API.
NOTE: This version requires a minimum of Java 11 to run!
Some highlights include:
- Improved switch pattern matching support
- Changed default settings to improve code output by default
- Fixed the "baby shark" bug (multiple nested infinite loops in a row)
- Optimized memory, CPU, and disk usage
