+Exact patch releases use SDKMAN's `X.Y.Z+P.B` notation, including in `.sdkmanrc`.
+For example, `java=17.0.20+1.1-librca` selects BellSoft's `17.0.20.1+1` release.
+Alternatively, `java-version: '17.0.20.1'` selects the newest build of patch 1,
+whereas `java-version: '17.0.20+1'` selects the exact unpatched build 1.
+Floating versions such as `17` prefer newer patches before comparing build numbers.
