Puzzle versioning

Puzzle versions use a subset of Semantic Versionsing 2.0.0.

A puzzle version is a string consisting of one, two, or three nonnegative integers, separated by .. The first integer is the major version, the second integer is the minor version, and the third integer is the patch version. The minor and patch versions are assumed to be zero when omitted.

Examples

• 1.2.3 has a major version of 1, minor version of 2, and patch version of 3
• 0.0.1 has a major version of 0, minor version of 0, and patch version of 1
• 0.6 has a major version of 0, minor version of 6, and patch version of 0
• 2 has a major version of 2, minor version of 0, and patch version of 0

• The major version should increment whenever changes are made to the puzzle definition that break log file compatibility.
• The minor version should increment whenever changes are made to the puzzle definition that break scramble compatibility.
• The patch version should increment whenever any other changes are made to the puzzle definition.

Whenever one version increments, the lower ones should be reset to zero.
