nvTiff library status and update

Today, I’am using the nvTiff library and encounter several issues (deadlock, performance issues, limitations). Since the last version 0.3.1 was released in november 2023. I would like to know if it is an abandoned project or if a new release is planned. In this case, I am open to help reporting issues, otherwise would it be possible to access the source code of the current version? Thank you
