The Scylla team is pleased to announce Scylla Rust Driver 0.3.0,
an asynchronous CQL driver for Rust, optimized for Scylla, but also
compatible with Apache Cassandra!

=== Notable changes ===

 * Connection management is heavily revamped:
   > a configurable pool of connections is kept per node or per shard
(Scylla only)
   > shard awareness is now also supported without a dedicated
shard-aware port (Scylla only)
   > several optimizations were applied to make this layer more robust
 * A CachingSession class is introduced - it allows creating a session
which automatically prepares its statements
   and maintains them in a local cache.
 * Colummn values can now be extracted from result rows by the column
name, not only by their index.
 * Handling user defined types is improved - when a new field is added
to the type, the driver is now still capable of reading the values.
 * A ValueList derive macro is now available - when it's applied to a
struct, an instance of this struct can be used as a list of values in
queries.
 * Client-side timestamps can now be defined for queries.
 * Tuples with null elements are now handled correctly.
 * Serial consistency level (for lightweight transactions) is now split
into a separate type in order to make it clear that it should not be
mixed with regular consistency level.
 * Shorter topology names, e.g. "SimpleStrategy" are now recognized and
accepted.
 * Internal queries now use paging internally in order to avoid
overloading the cluster and the driver with large requests.
 * Serialization path got optimized.
 + lots of other fixes and improvements

Congrats to all contributors and thanks everyone for using our driver!
