Hello everyone! ``` This is ASPECT newsletter #98. ``` 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: [#3405](https://github.com/geodynamics/aspect/pull/3405): Ability to interpolate multiple properties (proposed by [sac-bsa](https://github.com/sac-bsa)) [#3404](https://github.com/geodynamics/aspect/pull/3404): Improve allocation of matrix blocks (proposed by [gassmoeller](https://github.com/gassmoeller)) [#3401](https://github.com/geodynamics/aspect/pull/3401): Three new features for the gravity\_point\_values postprocessor (proposed by [LudovicJnnt](https://github.com/LudovicJnnt)) [#3400](https://github.com/geodynamics/aspect/pull/3400): Immediately overwrite the statistics file upon restart. (proposed by [bangerth](https://github.com/bangerth); merged) [#3398](https://github.com/geodynamics/aspect/pull/3398): update parameters (proposed by [tjhei](https://github.com/tjhei); merged) [#3397](https://github.com/geodynamics/aspect/pull/3397): Use correct dates in a changelog entry.
