The lastest release of Agroal is here. Amongst the biggest changes are the way connections are created that was changed to allow parallel creation. Another noteworthy change is a fast flush when there is a validation failure.
New features include configuration for the retries on connection creation and new settings to control network timeouts.
There are also a number of bug fixes related with concurrent transaction timeouts, including AG-300 that was backported to 3.0, 2.8 and 2.7 branches.
This version had contributions from Dennis Kniep, Ronald Milk and Marco Sappe Griot.
