3        * sparsehash: initial release:
4          The sparsehash package contains several hash-map implementations,
5          similar in API to SGI's hash_map class, but with different
6          performance characteristics.  sparse_hash_map uses very little
7          space overhead: 1-2 bits per entry.  dense_hash_map is typically
8          faster than the default SGI STL implementation.  This package
9          also includes hash-set analogues of these classes.

13        * sparsehash: version 0.2 release
14        * Preliminary support for msvc++ compilation. (csilvers)
15        * Documentation fixes -- some example code was incomplete! (csilvers)
16        * Minimize size of config.h to avoid other-package conflicts (csilvers)
17        * Contribute a C-based version of sparsehash that served as the
18          inspiration for this code.  One day, I hope to clean it up and
19          support it, but for now it's just in experimental/, for playing
20          around with. (csilvers)
21        * Change default namespace from std to google. (csilvers)

25        * sparsehash: version 0.3 release
26        * Quiet compiler warnings on some compilers. (csilvers)
27        * Some documentation fixes: example code for dense_hash_map. (csilvers)
28        * Fix a bug where swap() wasn't swapping delete_key(). (csilvers)
29        * set_deleted_key() and set_empty_key() now take a key only,
30          allowing hash-map values to be forward-declared. (csilvers)
31        * support for std::insert_iterator (and std::inserter). (csilvers)
