What's new in this version

Updates that will affect full-chemistry benchmark simulations

Feature	Contributor(s)	Model scope	Notes and references
Fix CEDS TMB emissions	Kelvin Bates (CU Boulder)	Emissions	geos-chem PR #2507 geos-chem PR #2683
HEMCO online dust extensions (DustDead, Tomas_DustDead) now use USTAR directly from met field input instead of computing it from winds	Yuanjian Zhang (WashU) Bob Yantosca (Harvard)	Emissions	HEMCO PR #279 geos-chem PR #2512 geos-chem PR #2711
New version of CEDS at 0.1 x 0.1 degree resolution	Dandan Zhang (WashU)	Emissions	geos-chem PR #2171
Bug fix: Emit C6H14 (hexanes) into ALK6 in CEDS 0.1 degree, CMIP, HTAP inventories	Bob Yantosca (Harvard)	Emissions	geos-chem PR #2696 NOTE: Hexanes were emitted into ALK4 instead, now fixed

Updates that will NOT affect full-chemistry benchmark simulations

Feature	Contributor(s)	Model scope	Notes and references
Need to increase memory for GCHP cloud benchmarks in GitHub action YAML file	Bob Yantosca (Harvard)	Benchmarking	GCHP benchmarks w/ CEDS 0.1 degree emissions exceeded a memory limit, causing the 1-hr and 1-month benchmarks to fail. GCHP PR #470 fixes this issue.
Set a C-preprocessor switch so that we can block out code specific to the KPP rosenbrock_autoreduce integrator	Bob Yantosca (Harvard)	Build	geos-chem PR #2689 geos-chem PR #2723
