In Equinox V4, stores now accept/provide events in two primary formats (previously everything was byte[]):
ReadOnlyMemory<byte>: Replaces byte[] as the default event body type, in order to facilitate pooling etc (EventStoreDB uses it directly, Equinox.DynamoStore maps internally to what the AWS SDK demands at present (MemoryStream))
JsonElement: Equinox.CosmosStore now natively uses System.Text.Json so event bodies can be emitted cleanly and directly using that format
The key change is that SystemTextJson now has two static type roots;
CodecJsonElement, which is for use with Equinox.CosmosStore V4 and later
Codec (which previously produced a JsonElement codec) that needed to be adapted for use with Equinox.CosmosStore is now equivalent in signature to Newtonsoft.Codec, and works directly with all other stores
