Bug fixes

  • Various smaller bug fixes.
  • Removed the mandatory client check for a match of the application Uri in the server certificate and the returned endpoint. Many production servers have it incorrectly configured. Open work item to make the check optional.
  • Winforms samples were moved to the samples repo. The Reference server Quickstart samples are available in a Nuget package from the preview feed.
  • Improve handling of client publish max request count. by @marcschier
  • The rejected store can be completely disabled (by @romanett) and the rejected certificate history can be limited with a new setting MaxRejectedCertificates. Rejected store is only supported with Directory store.
  • Better support for client browse with a ManagedBrowse implementation, which handles BrowseNext and all various types of errors that can occur. Implicitely also used by the NodeCache and other API that exposed browse functionality. by @ThomasNehring.
  • Reduce Server NodeManager contention on high load by moving some dictionaries to ConcurrentDictionary to avoid blocking in service calls.
  • Fix a server deadlock in channel cleanup.
  • More fuzz targets for the Xml Encoder/decoder. Now all encoders follow the dispose pattern.

Breaking changes

  • ICertificateStore has a new member NoPrivateKeys and a new method AddRejected optimized to save certs with low overhead.
  • CertificateStoreIdentifier.OpenStore has been flagged deprecated to allow for certificate caching.
  • CertificateStoreIdentifier with DirectoryStore supports to cache certificates if the store is just closed, not disposed.
  • Removed https package from OPCFoundation.NetStandard.Opc.Ua and marked it deprecated. Recommended is to set a dependency only to required packages, e.g. Server, Client, GDS.Client etc. to minimize the number of dependencies.
  • The Basic128Rsa15 policy has been removed from server configurations. It is considered unsafe and should only be used when connecting to legacy devices with no other option.
