• Registering package: Rimu
• Repository: https://github.com/RimuQMC/Rimu.jl
• Created by: @joachimbrand
• Version: v0.14.0
• Commit: 340e76631190a928b399c6937b472e5572b6cd60
• Reviewed by: @joachimbrand
• Reference: RimuQMC/Rimu.jl@340e766#commitcomment-150755032
• Description: Random Integrators for many-body quantum systems
• Release notes:

## Breaking changes
- IDs for replicas and spectral states are swapped: replica ids defining
the row in the matrix of `state_vectors` now are appended first and
spectral ids second. If there is only a single replica, or a single
spectral state, the respective ids are ommitted.
- Remove `BoseFS2C`, `BoseHubbardMom1D2C`, `BoseHubbardReal1D2C`. These models were moved to another package, see [RimuLegacyHamiltonians.jl](https://github.com/RimuQMC/RimuLegacyHamiltonians.jl)

## New features
- new module `Rimu.InterfaceTests` with functions 
 - `test_observable_interface`
 - `test_operator_interface`
 - `test_hamiltonian_interface`
 - `test_hamiltonian_structure`
- `ReducedDensityMatrix`
- `build_basis` is faster (using threading) and can work on address type

## Deprecations 
- in keyword arguments to `ProjectorMonteCarloProblem`
  - `maxlength` deprecated, replaced by `max_length`
  - `walltime` deprecated, replaced by `walltime`
- `lomc!` now prints a deprecation warning

## Internal changes
- fix random seeding of tests
- Documentation rework and docstring changes
- remove `lomc!` from most tests

## Bug fixes
- normalisation in `single_particle_density`
