[odow]

Basic

• version field of Project.toml has been updated
  - If a breaking change, increment the MAJOR field and reset others to 0
  - If adding new features, increment the MINOR field and reset PATCH to 0
  - If adding bug fixes or documentation changes, increment the PATCH field

Documentation

Tests

• https://github.com/jump-dev/MathOptInterface.jl/actions/runs/7480791502

The packages failing are:

• MathOptSetDistances -- due to Hypatia
• Alpine -- due to Pavito. Needs Prep for v0.3.8 Pavito.jl#75
• Hypatia -- upstream problem Prep for v0.7.4 Hypatia.jl#832
• Pavito -- caused by this release, but fixed in Fix fixing int variable constrained to Interval set Pavito.jl#74
• ProxSDP upstream problem Fix support for MOI.TimeLimitSec mariohsouto/ProxSDP.jl#101
• SDPA upstream problem Rebuild JLL for Julia 1.10 SDPA.jl#56
