Release v0.60

What's Changed

• Implement the USHORT, 16-bit assigned table data support. by @tpn in #43. This significantly improves performance when solving tables that have less than 64k vertices. This behavior is enabled by default. To disable it, use --DoNotTryUseHash16Impl.
• Introduce new --BestCoverageTargetValue=N command line parameter.
• Various tweaks and performance improvements.

Full Changelog: v0.59...v0.60

Release v0.59

• Introduce new function hooking support in order to do real-world performance evaluations of compiled perfect hash tables.
• Add an InterlockedIncrement() CPH routine.
• Various fixes and tweaks.

What's Changed

• Issue41 add penter hooking support by @tpn in #42

Full Changelog: v0.58...v0.59

Release v0.58

• Implement new live console output during solving.
• Fix generated compiled hash tables such that they compile and work on Apple Mac Silicon (M1/ARM64).
• Implement new logic for tracking cache line occupancy in the assigned array.
• Miscellaneous improvements.

Full Changelog: v0.57...v0.58

Release v0.57

• Add IACA markers to all compiled outputs, allowing iaca.exe to be run against the resulting .dlls.
• Update and improve usage docs.
• Implement AVX2 and AVX512 optimized versions of GraphHashKeysMultiplyShiftR.
• Implement --DoNotUseAvx2MemoryCoverage parameter.
• Implement --Remark parameter.
• Implement --MaxSolveTimeoutInSeconds parameter.
• Fix a bug that prevented --Compile from working.

Release v0.56

• Implement two new hash functions: Multiply643ShiftR and Multiply644ShiftR.
• Upgrade everything to use VS 2022.

Release v0.55

• Implement new graph backend (--GraphImpl=3). Provides big speedups in lots of workflows.
• New command line options for limiting number of attempts made.
• ETW improvements.

Release v0.54

Implement linear regression and score/rank against the assigned coverage array.

Release v0.52

• Implement a new graph assignment method based on NetBSD's nbperf. Controlled by --GraphImpl. This method is now default, and is incredibly faster than the previous version (upwards of 50% reduction in runtime).

• Implement --MinNumberOfKeysForFindBestGraph.

• Implement --MaxNumberOfEqualBestGraphs and fix logic surrounding lowest/highest best graph comparators.

Release v0.51

Implement support for random number generators.

Release v0.50

• Introduce graph collisions during assignment as a new coverage type.
• Implement memset in assembly to get around the issue with the previous release that PGInstrument builds crashed immediately upon startup.
