"major" - Holds the major version number as an int
"minor" - Holds the minor version number as an int
"patch" - Holds the patch version number as an int
"hex" - Holds the full version number encoded as an hexadecimal int with one byte (2 places) per number (see example below)
"status" - Holds the status (e.g. "beta", "rc1", "rc2", ... "stable") as a String
"build" - Holds the build name (e.g. "custom-build") as a String
"string" - major + minor + patch + status + build in a single String
The "hex" value is encoded as follows, from left to right: one byte for the major, one byte for the minor, one byte for the patch version. For example, "3.1.12" would be [code]0x03010C[/code]. Note that it's still an int internally, and printing it will give you its decimal representation, which is not particularly meaningful. Use hexadecimal literals for easy version comparisons from code:
[codeblock]
if Engine.get_version_info().hex >= 0x030200:
# do things specific to version 3.2 or later
else:
# do things specific to versions before 3.2
[/codeblock]
