Added

• New callback API for efficient custom match processing (#58)
• Byte-based scanning API for direct operation on byte[] and ByteBuffer without String overhead
• New hasMatch methods for quick existence checking that terminate immediately on first match (#68)

Performance

• Reduced memory usage for UTF-8 string mapping by dynamically selecting optimal array type

Fixed

• Fixed upstream vectorscan correctness regression on x86 architecture with targeted patch (#228, #231)
• Ensured all native handles are properly reclaimed after database compilation (#230)
• Reworked UTF-8 position mapping to handle the mapping correctly in edge cases (#170)

Changed

• Removed 255 thread limit for concurrent scanning operations (#222, #229)

Due to missing arm64 supoort amd proprietary licensing of new releases of hyperscan, this release of hyperscan-java transitions from hyperscan to the vectorscan fork.

Breaking

• Windows support has been dropped due to vectorscan not supporting it

Added

• Support for ARM64 architecture on Linux and macOS (M1/M2/M3 family of chips)

Fixed

• Database instances not reclaimable by GC (#161) - thanks @mmimica!
• Race condition during tracking of native references on multiple threads (#158) - thanks @mmimica!
• Expression IDs now can have arbitrary space between them without consuming additional memory (#163) - thanks @mmimica!
• Removed superflous duplicate call during mapping of expressions in PatternFilter (#205) - thanks @Jiar!

Added

• New PatternFilter allowing for prefiltering of java regex patterns similar to chimera
• Windows support
• Possibility to manually specify expression ids

Changed

• Moved access to native library from JNA to JavaCPP
• Removed context object from expressions

Fixed

• Lock contention while scanning with high concurrency (#89)

This release contains the following changes:

• Hyperscan v5.1.1 binaries (#48)
• Java 11 compatibility (#54)
• Logical combinations (thanks to @swapnilnawale @digitalreasoning for the contribution) (#55)

This release fixes:

• Segmentation fault when passing null value as expression (#34)

This release also features better error reporting (#32, thanks @eliaslevy!).

This release fixes:

• Error due to reading of structs after call to free (#31)

Changes:

• Support for 32-bit Linux
• New hyperscan binaries (v4.6.0)
• Updated JUnit and Surefire plugins for testing (works now with the most recent IntelliJ release)

This release contains the following changes:
