Hello everyone!

This is ASPECT newsletter #240.  
It automatically reports recently merged features and discussions about the ASPECT mantle convection code.

Below you find a list of recently proposed or merged features:

[#7017](https://github.com/geodynamics/aspect/pull/7017): add cmcrameri to env-py\_aspect.yml (implemented by [JarettBakerDunn](https://github.com/JarettBakerDunn); reviewed by [gassmoeller](https://github.com/gassmoeller))  
[#7015](https://github.com/geodynamics/aspect/pull/7015): Bump actions/checkout from 6 to 7 (implemented by [dependabot[bot]](https://github.com/apps/dependabot); reviewed by [gassmoeller](https://github.com/gassmoeller))  
[#7014](https://github.com/geodynamics/aspect/pull/7014): Small style improvements and another tutorial (implemented by [gassmoeller](https://github.com/gassmoeller); reviewed by [tjhei](https://github.com/tjhei))

[#7012](https://github.com/geodynamics/aspect/pull/7012): Simulator–\>compute\_reactions: Apply hanging node constraints to distributed\_reaction\_vector (implemented by [GTAIto](https://github.com/GTAIto); reviewed by [gassmoeller](https://github.com/gassmoeller))  
[#7011](https://github.com/geodynamics/aspect/pull/7011): Set convert unit to big endian for FastScape (implemented by [anne-glerum](https://github.com/anne-glerum); reviewed by [gassmoeller](https://github.com/gassmoeller))  
[#7009](https://github.com/geodynamics/aspect/pull/7009): Temporarily switch FastScape branch in tester (implemented by [anne-glerum](https://github.com/anne-glerum); reviewed by [gassmoeller](https://github.com/gassmoeller))

[#7002](https://github.com/geodynamics/aspect/pull/7002): Fix fastscape test output (implemented by [anne-glerum](https://github.com/anne-glerum); reviewed by [gassmoeller](https://github.com/gassmoeller))  
[#6997](https://github.com/geodynamics/aspect/pull/6997): Set bedrock diffusivity in tests to something very small instead of -1 (implemented by [anne-glerum](https://github.com/anne-glerum); reviewed by [gassmoeller](https://github.com/gassmoeller))  
[#6991](https://github.com/geodynamics/aspect/pull/6991): Allow multiple particle managers to have different output intervals and formats (implemented by [anne-glerum](https://github.com/anne-glerum); reviewed by [gassmoeller](https://github.com/gassmoeller))

And this is a list of recently opened or closed discussions:

[#7018](https://github.com/geodynamics/aspect/issues/7018) Fastscape coupling and instability + sensitive to mesh resolution. (opened)  
[#7016](https://github.com/geodynamics/aspect/issues/7016) Does the debug check on QLS particle interpolation use a too strict tolerance? (opened)  
[#7010](https://github.com/geodynamics/aspect/issues/7010) check\_diffusion\_time\_step in FASTSCAPE coupling (opened)  
[#7008](https://github.com/geodynamics/aspect/issues/7008) contrib/python/env-py\_aspect.yml unable to create conda environment (opened)  
[#6912](https://github.com/geodynamics/aspect/issues/6912) Have individual output intervals and file formats for each particle manager (closed)
