- Port support for ECC NIST/Brainpool profiles from prototyping_ecc branch
- Implement CertProvider to load certs per connection / profile
- Backward compatibility of configuration for existing apps
- SecurityConfiguration specifies app cert types for each profile
- Autodetect the ECC support for brainpool/nist based on platform (mac OS 10 doesn't support brainpool)
- ECC supported on net48 / net5.0 / net 6.0 / netstandard2.1
- ECC supported on windows / linux / macOS (brainpool not < macOS11)
- Self signed certs for each profile are created on start similar to RSA
- RSA only profiles are supported on .NET standard 2.0

- Add a light weight AddRejected certificate store method to `ICertificateStore` to ensure rejected cert history remains small and doesn't have a lot of overhead.
- Number of history certificates is configurable using a new `MaxRejectedCertificates` entry.
- Rejected certs are only saved to directory cert store, others do ignore the attempt
- Fix the caching of `CertificateValidator` and flag some `ÒpenStore` methods deprecated which do not support the caching. Fixes across the board to support the methodology. Basically `store.Close` keeps the cache, `store.Dispose` clears the cache, so recommendation is to use `var store = certStoreIdentifier.OpenStore(); try { ... }-- finally { store.Close }`
Improvements for complex types.
- Support to encode/decode complex type structures with multidimensional arrays.
- Perf improvements for type loader using new NodeCache fetch multiple interfaces.
- DataTypeDictionary validation when dependencies are used.
- interface for complex type resolver, to build custom types in code.
- improvements of console client to demonstrate browse/read of custom values
+++ Breaking changes +++
IDecoder interface change of the `ReadArray` method
- Return type is now `Array` for all types of arrays. Previously the method returned an array for 1-dim and a `Matrix` type for multidimensional arrays. In addition the convention in generated code is to use `Collection` for all 1-dim arrays, and so was built the `BaseComplexType`. The new convention is to expose the native `Array` type from a complex type, in all cases, hence the return type of `ReadArray` was changed to reflect that for a consistent programming model.
- `ReadArray` has a new parameter `systemType` to efficiently read encodeable types. Previously the `Type` of an encodeable was determined by the encodingid and lookup in the type factory, even when the Type is already known by the caller. The 'old' style is still supported.
- `ReadArray` supports to read encodeable type arrays which are directly encoded in structures. These arrays differ from standard encoding of arrays and they are handled when `BuiltInType.Null` is used as parameter.
- set `KeepAliveTimeout` default back to 5s, was unintentionally set to 50s in 368 release
- fix a bug that duplicate subscriptions were created after reconnect when transfer succeeds.
- add a property to enable subscription transfer in reconnect, set `Session.TransferSubscriptionsOnReconnect=true` to enable, IOP issues may not allow to use it with some servers.
- add a `SessionReconnectHandler(true)` constructor to support reconnect abort, if the connection recovers before reconnect timer called. If the new constructor is used, its a breaking change: Needs check of `Session` property in Reconnect handler callback, if aborted `Session==null`.
- Reduce warning log output if server timestamp > client time.
- Add handling when subscriptions can not be transferred, e.g. when false user credentials or no security prevent transfer.
- Improve the reconnect timer handling by using `OperationLimit` in reconnect.
- Add sample for `SessionReconnectHandler` in console client.
- Seperate session sample code from `UAClient`.
- Tested on popular demo servers of various SDK vendors.
- Fix Winforms ref client
- support for Microsoft.Extensions.Logger.ILogger in Opc.Ua.Core as the new logging interface
- backward compatible with config and TraceEvents
- new API Utils.SetLogger allows to set ILogger
- updated Console samples to demonstrate ILogger support with Serilog
- support for EventSource logging
