Cool, thx! Just curious, features are the most important ones for you?

Didn't 4.2 mainly add clang -x cuda support? (which I like a lot, but we don't cover that one in CI yet for AMReX/WarpX)
Trying to parse the change log: https://ccache.dev/releasenotes.html

I'm not exactly sure how the release notes map to the actual code changes, but even using nvcc, I saw much faster recompilation with 4.2. Maybe it also learned to be more clever about interposing itself with the host compiler or something

Update memaster (#110)
033b51e 
* Fix Init of Vector Members (ECP-WarpX#2595)

Fix default init of `Vector` member variables. The old construct
is not valid C++.

https://stackoverflow.com/a/11491003/2719194

* C++17: Work-Around NVCC gatherParticles (ECP-WarpX#2596)

The `noexcept` lambda does not compile in C++17 mode due to an NVCC compiler bug, at least in NVCC 11.3.109. Compiles in C++14 mode with the same compiler.

* requirements.txt - PICMI development version (ECP-WarpX#2588)

Document in `requirements.txt` on how to install a pre-release
version of PICMI.

* CONTRIBUTING: Update/Modernize (ECP-WarpX#2600)

* CONTRIBUTING: Update/Modernize

- Add GitHub account setup
- Add local git setup
- Modernize for CMake workflows

* Apply suggestions by Edoardo

Co-authored-by: Edoardo Zoni <59625522+EZoni@users.noreply.github.com>

* Replaced duplicated current deposition documentation (ECP-WarpX#2604)

* Throwing a warning if particle_shape>1 with EB (ECP-WarpX#2592)

* Aborting if particle_shape!=1 with EB

* Throw warning instead of aborting

* Checking at runtime if EB is initialized

* Added missing preprocessor directive

* Ignoring an unused variable

* Fix typo

* Improve style

Co-authored-by: Axel Huebl <axel.huebl@plasma.ninja>

* Fix segfault when importing _libwarpx without initializing WarpX (ECP-WarpX#2580)

* Added check for if warpx was initialized when calling finalize

* Renamed to be warpx_initialized

* Fixed reference to global variable

Co-authored-by: Peter Scherpelz <31747262+peterscherpelz@users.noreply.github.com>

* Changed global variable to member of libwarpx

* Fixed syntax errors

* Remove custom arg from argv to avoid parmparse error

Co-authored-by: Peter Scherpelz <31747262+peterscherpelz@users.noreply.github.com>

* Added parallel pragma to ApplyBoundaryConditions (ECP-WarpX#2612)

* Note that CCache 4.2 introduced large CUDA improvements (ECP-WarpX#2606)

* Dimensionality Docs: Default (ECP-WarpX#2609)

Just adds the note that 3D is the default geometry.

* AMReX: Weekly Update (ECP-WarpX#2613)

* MergeBuffersForPlotfile: Barrier (ECP-WarpX#2608)

Make sure that all MPI ranks are in sync, i.e., have closed the
files that they wrote, before trying to merge them.

* Fix installation location for libraries (ECP-WarpX#2583)

During configuration the installation location for libraries is given by
dumping the cmake variable `CMAKE_INSTALL_LIBDIR`.
This commit adjusts the installation of WarpX libraries (WarpX_LIB=ON)
to respect this setting.
