## Version 2.8

Minor change to avoid segfault when program exits with `exit(...)` function.

## Version 2.7

Fix incorrect initialization.

## Version 2.6

Use a more robust mutex (by using `std::recursive_mutex` instead of

Minor refactorings.

## Version 2.5

Added support for realloc().

## Version 2.4

Fixed free() not actually calling real_free().

Fixed nullptr dereference during free.

## Version 2.3

Added ids to each chunk of allocated memory to make it easier to keep track of
which allocated memory refers to which unfreed memory.

## Version 2.2

Minor refactoring: remove unused constexpr declarations in header.

Change implementation to not print when malloc/calloc/free is called if the
"ANOTHER_MEMCHECK_QUIET" environment variable is defined.

## Verison 2.1

Previous implementation did not fully account for total size of a call to
calloc. This version should fix this.

## Version 2.0

Minor refactorings.

Change internal implementation of linked list to be doubly-linked.

Add support for calloc.

Add pthreads to mutex-lock malloc/calloc/free.

## Version 1.0

Initial version with working `AnotherMemCheck`.
