What's New?

Evo change history.

Version 0.5.1 - May 2019

• Add EVO_ENUM_TRAITS() and EVO_ENUM_CLASS_TRAITS()
• Add Additional Formatting with FmtTable, fmt_table(), fmt_table_nocache()
• Add PureBase for a common empty base class
• Add STL string_view compatibility to StringBase
• Updated and simplified Cortex, removed cortex_module.h and moved contents to cortex.h
  • Renamed ModuleBase to CortexModuleBase, and renamed related types too
• Updated Benchmark: Add warmup_count to constructor, simplify helper macros, improved report output
• Updated StrTok (and variants) to use const StringBase& arguments to support for STL string compatibility
• Updated List and String methods: add/prepend/insert/replace now support copying from SubString or pointer in the same list/string (previously undefined behavior)
  • Note that String::replace() where source and destination overlap still results in undefined behavior
• Bug fix: EventThreadPool not working correctly in MSVC 2017, MSVC 2013, FreeBSD
• Bug fix: Cortex items not "relocatable", insert order no longer tracked
• Bug fix: GCC 4.6 and 4.4 compiler errors

• Bug fix: MSVC security warning on _open()
• Bug fix: Cygwin GCC x86 signed/unsigned warnings
• Bug fix: Fixed missing async dir in previous release
• Various documentation updates
• Add FAQ and benchmarks in Github Home
