2.6.45

• Adds: Nullable reference type annotations (#2041 by @NickCraver)
  • Adds annotations themselves for nullability to everything in the library
  • Fixes a few internal edge cases that will now throw proper errors (rather than a downstream null reference)
  • Fixes inconsistencies with null vs. empty array returns (preferring an not-null empty array in those edge cases)
  • Note: does not increment a major version (as these are warnings to consumers), because: they're warnings (errors are opt-in), removing obsolete types with a 3.0 rev would be binary breaking (this isn't), and reving to 3.0 would cause binding redirect pain for consumers. Bumping from 2.5 to 2.6 only for this change.
