Github release plugin, Kotlin, Okio and OkHttp updated
Toml4j removed and replaced with 4koma - improves null safety, immutability, TOML compliance

SpaceSafeURI replaced with PackwizPath which handles special characters much better (fixes#5)
Fixed directory traversal issues
Hashing system rewritten for better type safety and cleaner code
Download mode changed to use an enum
Request system completely rewritten; now uses OkHttp for HTTP requests (fixes#36, fixes#5)
Added request interceptor which retries requests (fixes#4)
Removed: support for extracting packs from zip files (and Github zipballs)
Cleaner exceptions; more improvements pending (in particular showing request failure causes)
Improved speed of cancelling in-progress downloads
Better support for installing from local files (no file: URI required; though it is still supported)
