Datetime serialization Changes 8.0.0-preview-0294 to 8.0.0

Hi , I'm currently using version 8.0.0-preview-0294 which store DateTime as string property in Cosmos DB like
2020-08-19T08:57:13.6677815Z

After updating to version 8.0.0 , I see it store DateTime as number property like
1609893960000

Due to which query condition which is based on DateTime is not working.

is there any way that we can keep the DateTime as it was before or It is recommended to update the data like it stores in version 8.0.0

I think changes is part of this commit.

Thank you !

It's an inherent consequence of how timestamps and dates are represented in GraphSON, and the actual conversion is done by the underlying Gremlin.Net library. The change you pointed out made sure that a DateTime will be store just like a DateTimeOffset.

There's probably a workaround for this, but it is of course highly recommended to use the latest format if you're early enough in your development. It won't be changed now that there's a stable version of Gremlinq 8.

Hi , Thank you for the quick response. I appreciate all the work you are doing on this library. It will be much better If we will have change log for the version so that it will helps to migrate to the version 8.0.0. I do not see any change log in release section.

I unfortunately don't have the resources to do changelogs for changes in preview-versions. The semantic version with a *preview suffix already gives a hint that things will break without further notice. I agree that more of everything would be awesome. Docs, support, etc. This is the current state of open source.

I recently got a sponsorship from what I think is your company. Thanks a lot. Leading by good example!
