• When using C++17,std::launder the reinterpreted pointer fromstd::aligned_storage to adapt to the change of object model introduced in P0137R1. Fix potential undefined behaviour.
• When exceptions are disabled, only print the error message to stderr whenTSL_DEBUG is defined instead ofNDEBUG
• Fix compatibility withstd::pmr allocators

• Fix issue#26, raise the maximum possible size of the hash table when using theprime_growth_policy on a 64-bit platform.
• Fix issue#31, whenmin_load_factor() > 0, theclear() method will also reset thebucket_count of the hash table to 0.
• Fix shrink whenmin_load_factor is set and a range erase withend() aslast is called. Them_try_skrink_on_next_insert was not correctly set.
• Fix issue#33, the value function of aconst iterator can now be called and returns a mutable reference to the underlyingvalue_type.

• Fix compilation error with GCC 9, the implicit copy/move constructor/operator of the iterator were not generated.

• Rename CMake project name fromtsl_hopscotch_map totsl-hopscotch-map for coherence with the convention used by most package managers. Thefind_package(tsl-hopscotch-map) command must now be used instead of thefind_package(tsl_hopscotch_map).
• Set bucket count for default constructed map/set to 0 to avoid any allocation.
• On Windows, addtsl-hopscotch-map.natvis to the installed files.
• Fix CMake >= 3.13 warning on Policy CMP0076 and add quotes to paths.
• Removecxx_std_11 fromtarget_compile_features to avoid a warning with older versions of CMake that don't support it. The warning was given even if thetarget_compile_features was surrounded in aif(${CMAKE_VERSION} VERSION_GREATER "3.7").

• Add installation rules in the CMake of the project.
• Add MSVC debugger visualization.natvis file.
• Fix issue#41 inmax_size() function resulting in compilation error. The variablebucket_hash::hash_type doesn't exist anymore due to previous refactoring. Remove thehopscotch_bucket::max_size as this is now obsolete.

• In CMakeList.txt, only use cxx_std_11 in target_compile_features when the CMake version is >= 3.8 (#37).
• Move thestatic_assert checking thatvalue_type is nothrow move constructible or copy constructible inside the constructor to avoid issues whenKey and/orT are not commplete types (#36).

General overhaul of the library introducing minor backward incompatibilities.

• Move the header files fromsrc toinclude/tsl for more coherence with other C++ libraries.
• For CMake users, add an exported targettsl::hopscotch_map to be used withtarget_link_libraries.
• Move growth policies from thetsl namespace to thetsl::hh namespace.
• AddGrowthFactor template parameter totsl::hh::power_of_two_growth_policy.
• Renamehopscotch_sc_map tobhopscotch_map andhopscotch_sc_set tobhopscotch_set.
• Check that themax_load_factor passed in parameter is between 0.1 and 0.95.

• Correct issue#31, a movedtsl::hopscotch_map ortsl::hopscotch_set can now still be used after a move. Previously the map ended up in a invalid state after a move but the standard mandates that a moved object should be in a valid (but unspecified) state so that it can still be used after a move.
• When a hash map or set with a bucket count of 0 is instantiated, no memory will be allocated.
• Additerator mutable_iterator(const_iterator pos) method to convert a const iterator to a mutable iterator.
• Add avoid clear() noexcept method to growth policies classes. If you use a customGrowthPolicy check the interface update.

• Additerator mutable_iterator(const_iterator pos) method.
• Add erase method taking a precalculated hash in parameter similar to lookup functions.
• Reduce default max load factor to 0.9.
• Add mandatorymax_bucket_count() method toGrowthPolicy to take into account the possible limitations of the growth policy.
• Fix the number of reserved buckets on range insert (i.e.void insert(InputIt first, InputIt last)). The amount was too low.

• Critical bug correction (#27), on rehash some elements were lost in the overflow list in some corner cases.
• Use std::uint_least* instead of std::uint* for better portability.
