3.11.5

Direct download: robin_hood.h

• #141: Use malloc + memset instead of calloc, which can be a bit faster, especially when the map gets large. Thanks @zhanglistar!
• #138: The return type of functions that use hints should be consistent with std. Thanks @acd1034!

3.11.4

Direct download: robin_hood.h

• fixes #131: add missing insert and emplace_hint methods. Thanks @slavenf!

3.11.3

Direct download: robin_hood.h

• bugfix: don't change hash multiplier when hash works well, this introduces the danger of getting an overflow

3.11.2

Direct download: robin_hood.h

• #125 Add missing include <limits>. Thanks @jpmorr!

3.11.1

Direct download: robin_hood.h

• Fix compiling with MSVC 2015 #118, thanks @jeremyg-lunarg!
• Support insert with initializer list, found by @xuanqing94
• Updated copyright to 2021
• overflow fix: rehash with different hash instead (#121). This uses a pretty nice method to get rid of potential overflow problems, by rehashing with a slightly modified hash. Thanks for @slavenf for making the problem reproducible!

3.10.0

Direct download: robin_hood.h

• new API compact(): if possible reallocates the map to a smaller one.
• Improve CMake integration in #105, thanks @Ryan-rsm-McKenzie!
• Switch to murmurhash3 in hash_int (it's not slower, but much higher quality hash)
• try_emplace and insert_or_assign now use a single lookup instead of two, in #116. Thanks @GilesBathgate for the proof of concept!

3.9.1

Direct download: robin_hood.h

3.8.0

Direct download: robin_hood.h

• Add member functions from C++17 #79
• Fix is_transparent typedef detection #78
• Add Conan package manager usage example #81
• Support hash for smart pointers, string views, and basic_string
