According to SemVer 2.0.0:

Build metadata MAY be denoted by appending a plus sign and a series of dot separated identifiers immediately following the patch or pre-release version. Identifiers MUST comprise only ASCII alphanumerics and hyphen [0-9A-Za-z-]. Identifiers MUST NOT be empty. Build metadata SHOULD be ignored when determining version precedence. Thus two versions that differ only in the build metadata, have the same precedence. Examples: 1.0.0-alpha+001, 1.0.0+20130313144700, 1.0.0-beta+exp.sha.5114f85.

However, the cmp function does not ignore build metadata:

degasolv.cli=> (use 'clj-semver.core)
nil
degasolv.cli=> (clj-semver.core/cmp "3.2.3+metadata" "3.2.3")
1

For example

(equal? "1.0.0-42" "1.0.0-rc1")

results in
