Important
enableUnsignedLongs in CelOptions is now enabled by default as of #410. Unsigned integer literals (uint) in CEL expressions will now be represented as com.google.common.primitives.UnsignedLong instead of java.lang.Long when evaluated. If your expressions expose these unsigned integer literals directly or you have custom functions that work with unsigned integers, you may need to explicitly disable this flag and make adjustments to avoid errors.
