Thanks; will get this released shortly (I have a similar set of local diffs that I forgot about)
If you get a chance, can you add a changelog entry please (I'll add after the merge if I get here first)
(Will also be doing same for Propulsion components)

@njlr I'll probably leave this as this is in Equinox.DynamoStore.Core, a rarely-opened namespace, but here are some details on why this happened:

The error stems from using the V9/10 compiler where the assembly references FSharp.Core <8 - the RequireQualifiedAccessAttribute is missing AttributeTarget.Stuct and the compiler complains. The fix is to up the FSharp.Core dependency to v8 (or use the older compiler)

anything else makes the case values (Forward/Backward) visible in the default namespace, which might not be a breaking change from the point of view of the API Validation, but can easily be a source breaking change for F# consumers

A prime example of where this does not make sense is https://github.com/jet/propulsion/blob/908e84f237a1b43c2a39d430df3a388f6e63d06a/src/Propulsion/Streams.fs#L295

(If it wasnt a binary breaking change, I'd drop the Struct before the RQA)
