Manopt v0.6.7

Diff since v0.6.6

The main part of this release is a large AI-assisted review of the code to spot inaccuracies, typos, and failing edge cases. I hope the small changes and fixes listed in the Changelog.md do not cause anyones code to fail, see XKCD 1172: Workflow

Added

• A BarzilaiBorweinStepsize as a standalone stepsize instead of only being available within the
  NonmonotoneLinesearchStepsize. (#641)
• a benchmark suite in benchmark/, written with BenchmarkTools.jl and run with AirspeedVelocity.jl,
  which on a pull request labeled benchmark compares it against master.
  It starts with two problems, the Riemannian mean on the sphere, benchmarked with gradient_descent
  and quasi_Newton, and the Riemannian median on hyperbolic space, benchmarked with cyclic_proximal_point. (#640)
• introduce a StepsizeInitialGuess that allows to use a Stepsize as initial guess of a line search. (#641)
• Runic.jl is now also used to check code formatting in the .qmd and .md files of the repository (#643)

Changed

• the changelog check in CI is skipped on pull requests labeled no changelog necessary; dependabot adds this label to its pull requests automatically. (#643)
• since has_converged exists, the status reports on REPL now use this to indicate whether an algorithm has converged. (#643)

Fixed

• Minor bug fix in the solver adaptive_regularization_with_cubics to work on complex manifolds (#644)

• Bump the all-julia-packages group across 2 directories with 3 updates (#646) (@dependabot[bot])

Closed issues:

• Rework Barzilai-Borwein rule to be able to use it as an initial guess for other line searches (#537)
• (A small section of) Benchmarks (#634)
