[dependabot]

Bumps proguard-base from 7.2.0 to 7.3.1.

Release notes

Sourced from proguard-base's releases.

7.3.1

Version 7.3.1

Kotlin support

• Add support for Kotlin 1.8.

Improved

• Conservative optimization is now the default. Previously, it could be enabled by setting the optimize.conservatively system property. This has been replaced with the -optimizeaggressively option, which sets optimization to aggressive.
• Improve optimization performance in edge cases with generated code. (#283)

Bugfixes

• Fix -keepparameternames to keep Kotlin function, constructor and property setter parameter names.
• Fix -keepparameternames to keep Kotlin annotation constructor parameter names.
• Fix -keepparameternames to keep Kotlin interface parameter names.
• Fix potential NullPointerException while processing enum classes with invalid Kotlin metadata.
• Fix potential Instruction has invalid constant index size error during GSON optimization.
• Fix member specialization & generalization optimizations.
• Fix potential "Сan't find referenced class ClassName$DefaultImpls" warnings. (#290)

7.3.0

Java support

To allow ProGuard to continue to optimize, obfuscate and shrink Java class files ProGuard now supports all Java versions including Java 19.

• Add support for Java 19. (PGD-247)

Kotlin support

ProGuard 7.3 deprecates the -keepkotlinmetadata option. You can use -keep class kotlin.Metadata instead which automatically enables processing of Kotlin metadata. Some consumer rules, from libraries such as kotlin-reflect, already contain this rule which means that Kotlin metadata processing will be enabled automatically in those cases.

• Add support for Kotlin 1.7.
• Improve support for Kotlin library projects. (T3752)
• Automatically process Kotlin Metadata when keeping the kotlin.Metadata annotation. (T3116)

Improved

• Improve app startup times when using -addconfigurationdebugging. (T17153)

Bug fixes

• Prevent merging classes with native methods that would result in UnsatisfiedLinkError.
• Fix optimization of simple enums (optimization class/unboxing/enums).
• Prevent potential build time NullPointerException when processing Kotlin interface methods.
• Fix ProGuard Gradle Plugin not working correctly on Windows. (PGD-272)
