- New finite-area/finite-volume boundary conditions:
- `clampedPlate`
- `timeVaryingFixedValue`
- `acousticWaveTransmissive`
- New base classes for `fvOption` of finite-area methods: `faOption`
- New `faOption`s:
- `contactHeatFluxSource`
- `externalFileSource`
- `externalHeatFluxSource`
- `jouleHeatingSource`
- New tutorial: `compressible/acousticFoam/obliqueAirJet`
