1.2.0

This release brings further phases of the new QuestDB Wire Protocol, namely:

• Durable acknowledgement; users can opt into receiving notifications that the flushed data has been safely replicated.
• QWeP; querying the database and returning the data using the new QWP.

Stay tuned for further upgrades, including store-and-forward support for zero data-loss client-server transfer.

Documentation to follow.
