Deprecations

This release includes the following deprecations:

• Context: Renamed to ContextV1
• Timestamp::from_gregorian: Renamed to Timestamp::from_gregorian_time

Change to Version::Max

Version::Max's u8 representation has changed from 0xff to 0x0f to match the value returned by Uuid::get_version_num.

Change to Uuid::get_version for the max UUID

Uuid::get_version will only return Some(Version::Max) if the UUID is actually the max UUID (all bytes are 0xff). Previously it would return Some if only the version field was 0x0f. This change matches the behaviour of the nil UUID, which only returns Some(Version::Nil) if the UUID is the nil UUID (all bytes are 0x00).
