June 23th, 1999
- RC2 code was cleared.
- RC6 was changed according to the specification. It is RC6 32/20/32.
  RC6, SAFER+, LOKI97 and CAST-256 codes are actually Dr Brian Gladman's
  code a bit modified for mcrypt.
- shared library version has changed (at last!)

June 22th, 1999
- SAFER+, LOKI97 and CAST-256 Added.

June 15th, 1999 - Version 2.2
- Changes in the xTEA algorithm. Some extra parenthesis made the algorithm
  differ from the specification. Pointed out by Lars Nordentoft
  <lntech@post9.tele.dk>

June 12th, 1999 - Version 2.1.1
- Changes in the documentation which was inaccurate.

June 11th, 1999 - Version 2.1
- _mcrypt_ was placed as a prefix to all internal functions so they
  do not pollute namespace.

May 29th, 1999
- test suites added
- Blowfish was divided to blowfish-448, -256, -192, -128.
- CBC can now accept IV
- mlock and munlock is used before mallocing and freeing any memory,
  thus if such capabilities exist the library guarrantees that no
  password is written in the disk (as swap etc.)
- gen_key_md5() was added and gen_key() was renamed to gen_key_sha1()
  gen_key() is still defined to be gen_keysha1().

May 26th, 1999 - Version 2.0
- Documentation was incorrect and innacurate. Corrected.
- A #define WORDS_BIGENDIAN 0 was removed from acconfig.h, this
  was confusing all the library headers, and thus the library was
  useless.
- nbit-ofb mode added. n is the blocksize of the algorithm. Still
  experimental.

May 24th, 1999 - Version 1.93
- defined get_block_size to be mcrypt_get_block_size so php3.0.8 compiles ok

May 17th, 1999 - Version 1.9
- gen_key() changed
- libtool support (based on Sascha Schumann's patches)
