 # Changelog

+## Versioning
+
+CyberChef uses the [semver](https://semver.org/) system to manage versioning: `<MAJOR>.<MINOR>.<PATCH>`.
+
+- MAJOR version changes represent a significant change to the fundamental architecture of CyberChef and may (but don't always) make breaking changes that are not backwards compatible.
+- MINOR version changes usually mean the addition of new operations or reasonably significant new features.
+- PATCH versions are used for bug fixes and any other small tweaks that modify or improve existing capabilities.
+
 All major and minor version changes will be documented in this file. Details of patch-level version changes can be found in [commit messages](https://github.com/gchq/CyberChef/commits/master).

 #### *The Cyber Swiss Army Knife*
 
-CyberChef is a simple, intuitive web app for carrying out all manner of "cyber" operations within a web browser. These operations include simple encoding like XOR or Base64, more complex encryption like AES, DES and Blowfish, creating binary and hexdumps, compression and decompression of data, calculating hashes and checksums, IPv6 and X.509 parsing, changing character encodings, and much more.

 The tool is designed to enable both technical and non-technical analysts to manipulate data in complex ways without having to deal with complex tools or algorithms. It was conceived, designed, built and incrementally improved by an analyst in their 10% innovation time over several years.
