Note that this basically obsoletes data-default-instances-*

[byorgey]

Does anyone know what the breaking changes are? There doesn't seem to be a changelog.

[tfausak]

I can't find a change log either. Here's the diff: mauke/data-default@1e4f789...8178c67

[tarleb]

I've opened an issue: mauke/data-default#28

[mauke]

Changes in 0.8.0.0:

• The split into multiple packages (data-default-class, data-default-instances-*) is gone. There is only data-default now (with no dependencies on data-default-class or anything).
• data-default only depends on containers and base now (but requires base >= 4.8).
• The Default instances for Data.DList and System.Locale are gone (but could be revived with updated versions of data-default-instances-dlist and data-default-instances-old-locale in the future?).
• The Default instances for e -> a and IO a have been removed.
• The "generic" default Default instance now supports sum types as well (by always choosing the left constructor).
• The internal GDefault type is now semi-public (in the Data.Default.Internal module) and has stub documentation.
• New instances:
  • Tuples of size up to 31 (previously 7)
  • Identity
  • Const
  • Proxy
  • Solo
  • Bool
  • CBool
  • Ptr
  • ConstPtr
  • FunPtr
  • IntPtr
  • WordPtr

The split into multiple packages (data-default-class, data-default-instances-*) is gone. There is only data-default now (with no dependencies on data-default-class or anything).

In that case, every package that depends on data-default-class or data-default-instances needs to be modified, right? So the above list is incomplete. I discovered this by trying to compile pandoc with the constraint data-default >= 0.8; it fails with an error building xml-conduit:

    • No instance for ‘Data.Default.Internal.Default X.ParseSettings’
        arising from a use of ‘def’

xml-conduit depends on data-default-class but not data-default.

[tfausak]

Yes, I ran into the same issue.

Ah I see - feels like this needs wider awareness, a Discourse post/announcement would probably make sense?
But okay I guess we could try to generate a list of dependents (I suppose data-default-class should be sufficient):

/cc @LaurentRDC . NB: Hakyll will have to wait until pandoc is updated.
