Future Plan

[ripytide]

I thought it was worth discussing the specifics of when to deprecate legacy items, several options I can think of:

• Deprecate everything legacy immediately
• Deprecate everything legacy in stages (how long between stages? what goes in each stage?)

There is also the question of when/how to remove the legacy items after they have been deprecated and a reasonable amount of time has passed, and what that reasonable amount of time should be.

It might also be worth documenting the decisions to these questions in the readme, so as the information is readily available to users, and then we just need to follow the plan.

I'd like to give users some time to catch up with the existing updates and deprecations.

I don't know how crates are going to migrate Gray now. Without the legacy flag it's not possible to swap v08 to v09, and without the Deref trick, the same source code can't be compatible with both.

I don't see an alternative to a hard-migration for the Gray pixel type, apart from people just deciding to not migrate, which is their prerogative.

Are there any plans to add indexed colors using bitfields packed into u16 and u8 ?

This like color types are used in cheap/old LCD controllers, and retro emulators with 1..6 bit color depths (surprisingly including modern e-Ink displays). So, narrow bit colors (linear or paletted) can be important for embedded Rust areas.
