# 2021-05-21 | A small update about rizin
{

  So many changes has been done by my friends and me in the past months,
  but here i will focus on the changes i did:

  - All the java plugins (assembler, disassembler, class parser and core plugin) has been rewritten, 
    including tests to validate decoders and encoders.
  - The AVR assembler and disassembler has also been rewritten (with tests).
  - The MD4 and SHA1 code has been rewritten, because they were GPL.
  - rz-hash and all the digest methods and code has been rewritten or heavily refactored to clean and
    remove quirks and hacks; moreover all the algorithms now are stateful, which allows to be used
    with big files and therefore doesn't require to allocate the whole file in memory.

  - Recently i have introduced the Ratcliff Obershelp Pattern Recognition algorithm in rizin, to remove
    the dependency of the diff utility and allow diffing any type of data; also rz-diff has been rewritten.
  - Currently there is an open push request that allows diffing 2 files interactively at byte level.

    

  All the rewritten code has been released within rizin under LGPL-3

  What is next? more refactoring; there are huge piece of code that really need to be rewritten to
  make all the utilities stable and working correctly.
