Dwave-hybrid

New Features
---

- Added `beta_range` option to `(Hybridized)PopulationAnnealing`
and `CalculateAnnealingBetaSchedule`
- `ProgressBetaAlongSchedule` now outputs `delta_beta`
in addition to `beta`
- Made `ProcessPoolExecutor` availability optional to enable
use on systems with process limitations

Fixes
---

- Expanded range of supported energies in `EnergyWeightedResampler`
- Linear beta schedule and better defaults in `PopulationAnnealing`
- Tests not included in the package anymore

Changes
---

- Deprecated use of `beta` in `EnergyWeightedResampler`. Use
`delta_beta` instead.

Fixes
---

- `hybrid.concurrency.process_executor` now optional

New Features
---

- Option to retry if embedding fails in `QPUSubproblemAutoEmbeddingSampler` (114)
- `ComponentDecomposer` for iterating over problem graph components (209)
- [`greedy`](https://docs.ocean.dwavesys.com/projects/greedy/en/latest/)-based `SteepestDescentProblemSampler`/`SteepestDescentSubproblemSampler`

Fixes
---

- `SplatComposer` was producing `numpy.float64` samplesets (235). Now it inherits `dtype` from input.

Fixes
---

- All QPU samplers now use client-based QPU selection instead of solver feature-based,
therefore allowing users to define the solver via Ocean configuration (228)

New Features
---
- Added `SubproblemCliqueEmbedder`

Changes
---
- Dropped Python 2.7 and 3.4 support

Fixes
---
- Loosened NumPy version requirements

Fixes
---

- Minor docs/doctests updates
