Durable Functions extension v3.0.0 is now in public preview. This new major version introduced two key changes: upgrade to the latest Azure Storage SDK and a new partition manager.
This SDK upgrade provides the latest performance, correctness, and security updates. However, it may be a breaking change for some .NET in-process users.
The new partition manager helps to reduce idle-state costs significantly for those using Azure Storage backend, especially v2 Storage accounts. In a benchmark, daily cost reduction is 93%. The new partition manager uses Azure Tables to manage partition assignments instead of Azure Blob leases, and in addition to being more cost efficient, it is also easier to debug.
