## Outputs

- Feature #1422: Offers the possibility to write results in binary. Petsc vector has been extended to enable reload of those values (see ThirdParty tickets below).
- __Feature #1421__: Changing the output directory so that each processor writes in its own folder and add an optional timestamp. _Note:_ the compatibility break here concerns tests and Ensight outputs.

## Utilities / ThirdParty

- Feature #1453	PetscVector: enrich the way a vector can be built with more reloading from files.

- Bug #1455: Vector::InitFromSequentialFile didn't work due to filler lines in Matlab format.
- Bug #1452: Reloading Petsc Vector didn't work as expected.

- Support #1451: PetscVector::AreEqual now also investigates the ghosts.

- __Design #1454__: PetscVector: modify the API of some methods to be more in line with the rest of the library.

## Core

- __Design #1456__: MoReFEMData: remove the awkward option to provide an additional subdirectory.

## Geometry:

- Bug #1445: Bug corrected in WriteMedit: ghosts were also required in the conversion array!
- Bug #1448: Mesh::AreVolumesBuilt() implementation was faulty.
- Bug #1449: Way of computing number of vertices, edges, faces and volume after processor reduction has been improved.
- Bug #1450: Exception about interface not built was not properly handled.

## FiniteElement

- Design #1458:	GodOfDof: modifying the underlying structure behind GetOutputDirectoryForNumberingSubset().

## Test

- Support #1272: Convert the FromVertexMatching test to activate it in the test suite.
- Support #1457: Set the timeout for each test.

- Bug #1442: Gitlab-CI: the warning check for macOS failed as an alpine Docker image was assumed and a shell runner was actually used

## Scripts

- Bug #1447: init_morefem.py script didn't work in macOS due to bad module path.

## XCode

- Support #1446: XCode class template: use C++ 17 namespace liberality to avoid many indenting stages.
