Upcoming Changes

BREAKING: Removed the use of the compatibility library to automatically generate macros and workaround for older compilers. The important compatibility workarounds like the __builtin_clz extension are still used, but workarounds for missing C++11 library features have been removed. In particular, the library now requires compiler support for noexcept, constexpr, alignof and thread_local. This means that GCC 4.8 and Visual Studio version 12.0 (both released in 2013), are now longer supported.

Adapter

BREAKING: Remove Mutex support from allocator_reference and consequently from std_allocator, allocator_deleter, ... Embedding the Mutex with the reference was fundamentally broken and unusable to ensure thread safety. Use a reference to a thread_safe_allocator instead, which actually guarantees thread safety.

Bugfixes

  • more CMake improvements

0.6-2

Various bug fixes, compiler warning workarounds and CMake improvements accumulated over past two years. Most notable changes:

  • cross compilation works now
  • fallback_allocator is default constructible if stateless
  • add unique_base_ptr to support a unique ptr to a base class
  • add allocate_unique overloads that take a custom mutex
  • allocator deleters are default constructible

0.6-1

  • fix CMake configuration error
  • fix double free error in segregator
  • add static_assert() when default constructing a stateful std_allocator
  • fix various compiler warnings

0.6

Tool

  • better MSVC support
  • improved compilation time

Core

  • add literal operators for memory sizes (4_KiB)
  • more flexible make_block_allocator
  • composable allocator concept

Allocator

  • improved temporary_allocator: explicit separation into temporary_stack, improved automatic creation
  • new memory_stack_raii_unwind for automatic unwinding
  • new iteration_allocator
  • make allocators composable
  • add facilities for joint memory allocations

Adapter

  • add shared_ptr_node_size
  • add string container typedef
  • add fallback_allocator
  • add segregator

Bugfixes

  • OSX support
  • various warnings fixed

0.5

  • improved CMake build system, now supports cmake installation and find_package()
  • improved low-level allocators and added malloc_allocator
  • add virtual memory interface and allocators
  • add allocators using a fixed-sized storage block
  • introduced BlockAllocator concept and various implementations
  • new class template memory_arena that is used inside the higher level allocators, allows more control over the internal allocations
  • add wrappers/adapters for the polymorphic memory resource TS
  • improved tracking classes
  • other improvements like concept checks and more exception classes
  • internal changes

0.4

  • polished up the interface, many breaking changes in the form of renaming and new header files
  • added unified error handling facilities and handler functions in case exceptions are not supported
  • improved old allocator adapters by introducing allocator_storage template
  • improved allocator_traits making them more powerful and able to handle Allcoator types directly
  • added type-erased allocator storage
  • added node-size debugger that obtains information about the container node sizes
  • most parts now work on a freestanding implementation
  • used foonathan/compatibility for CMake compatibility checks
  • added miscellaneous tiny features all over the place
  • many internal changes and bugfixes

0.3

  • added debugging options such as memory filling and deallocation and leak check
  • improved performance of pool allocators
  • changed complete project structure and CMake
  • many internal changes and bugfixes and automated testing

0.2

  • added temporary_allocator as portable alloca
  • added small_node_pool type optimized for low-overhead small object allocations
  • added various allocator adapters including a thread_safe_allocator for locking
  • better compiler support
  • many internal changes and bugfixes

0.1-1

  • critical bugfix in memory_stack
  • added smart pointer example

0.1

  • first beta version
