### [8.33.0] - 2019-06-27
|
||||
- 'Bzip2 Compress' operation added and 'Bzip2 Decompress' operation greatly improved [@artemisbot] | [#531]
|
||||
|
||||
### [8.32.0] - 2019-06-27
|
||||
- 'Indec of Coincidence' operation added [@Ge0rg3] | [#571]
|
||||
|
||||
### [8.31.0] - 2019-04-12
|
||||
- The downloadable version of CyberChef is now a .zip file containing separate modules rather than a single .htm file. It is still completely standalone and will not make any external network requests. This change reduces the complexity of the build process significantly. [@n1474335]
