Release 1.0.0

[c42f]

As discussed over at #522, it's almost time for a 1.0.0 release. Personally I think there should be no great breaking changes here and we should try to make it compatible with the status quo of the last year or so. However, we can take the opportunity to make it as consistent with the final state of julia-1.0 Base as possible via a few targeted deprecations (with proper depwarns).

Here's a TODO list (moved from prior discussion at #522). Feel free to add or suggest items.

• Triage past issues & add any v1.0 milestones
• Triage current PRs & add any v1.0 milestones
• Deprecations
  • Remove v0.9 deprecations (Drop Julia v0.7 support, remove deprecations #525)
  • Deprecate SDiagonal in favor of Base.Diagonal Replace SDiagonal with LinearAlgebra.Diagonal of SVector #531
  • Remove deprecated FixedSizeArrays module
• A way forward for constructors
  • Make sure we have a strategy for Inconsistencies with multi-argument constructors #518 (probably WIP/RFC: Implement SA[...] syntax for SArray literals #633 or WIP new @SA macro and comprehension support #636)
  • Deprecate (most of?) the zoo of constructor macros (replace with WIP/RFC: Implement SA[...] syntax for SArray literals #633 ?) but keep them around in the 1.0 release cycle. Can be soft-deprecated later
  • Constructors with generators or ntuple like syntax Constructing StaticArrays with generators or ntuple-like syntax #97 Can be done later
  • Fix SVector{0}(::Vector) will not construct #520
  • Fix error creating empty MVector #557
• Revisit axes; SUnitRange etc to consider whether these design changes should go into 1.0 Too big for 1.0
  • Tidy up usage of SOneTo (follow up of Add SOneTo as AbstractUnitRange to represent axes(::StaticArray) #534; see also export & document SUnitRange #620)
  • Export of SUnitRange export SUnitRange #474
  • Consider modernizing & merging WIP Return SUnitRange from indices(::StaticArray) #150
• Resolve fallout from Fix all the things #503 where possible (eltype becoming Union{}) cf. Adding n x 0 matrices results in Union{} eltype #528
• Consider whether we can avoid promoting MArray to SArray quite so often Broadcast return type for MArrays #327

Presumably the FixedSizedArrays compatibility layer can also be removed?

[mschauer]

Yes, it is deprecated and was vendorised in the only dependence: JuliaGeometry/GeometryTypes.jl#153

[c42f]

Good idea, see #600.

Will release v1.0.0 have any breaking changes?

[c42f]

Probably a few more deprecations to come during cleanup but nothing specifically on my mind. Currently it seems that bumping major versions of widely used packages is a bit more disruptive than would be ideal, so it would seem best to wait until we have a batch of breaking changes.

There's no plan for a major rewrite or large change in the APIs though; it's mostly incremental maintenance at this stage.

Just wanted to say thanks for all the effort you've put into the package lately, @c42f!

[c42f]

Thanks Twan, I'm slowly chipping away at cleaning a few dark corners of the implementation :-)
