**January 11 2024 :: QCEFF. Tag v11.0.0**

Nonlinear and Non-Gaussian Data Assimilation Capabilities in DART

- Adds a Quantile-Conserving Ensemble Filtering Framework (QCEFF) to DART.
Publications: `QCEFF part1 <http://n2t.net/ark:/85065/d7mk6hm4>`_,
`QCEFF part 2 <http://n2t.net/ark:/85065/d7nv9pbt>`_.

- The default QCEFF options are EAKF, normal distribution (no bounds).

- User interface changes:

- filter_kind is now a per-qty option through QCEFF table.

- Two new required namelists (add to input.nml files):

- probit_transform_nml
- algorithm_info_nml

- assim_tools_mod namelist:

- sort_obs_inc namelist option applied to ENKF only, so default is now .true.
- ``spread_restoration`` is not supported in this version

- algorithm_info_mod QCEFF options read at runtime from .csv or .txt file


- New probability distribution modules:

- beta_distribution_mod *contributed by Chris Riedel*
- bnrh_distribution_mod (bounded normal rank histogram)
- gamma_distribution_mod
- normal_distribution_mod

- probit_transform_mod
- distribution_params_mod

- Update to lorenz_96_tracer_advection:

- positive_tracer
- more tracer namelist options available and changed defaults
- updated perturbation routine
- bug-fix: real(r8) rather than real(i8)

- Fix: obs_def_1d_state_mod (oned forward operators):

- For non-integer powers, fix up values for negative bases

- Documentation:

- main page section on Nonlinear and Non-Gaussian Data Assimilation Capabilities in DART
- QCEFF instructions: Quantile-Conserving Ensemble Filter Framework
- Example to work through: QCEFF: Examples with the Lorenz 96 Tracer Model

**January 9 2024 :: Derecho CLM-DART. Tag v10.10.1**

- CLM-DART scripting updated for Derecho.
- CLM-DART SourceMods packaged with DART.
- Reinstituted both 'complete' and 'single_year' datm streamlist files in shell scripts
due to delays when initializing the CAM reanalysis files through campaign/collections directory.

bug-fixes:

- Fixed format statement in assert_mod to conform to Fortran standards.
- Fixed debugging output for failed forward operators.

doc-fixes:

- Remove broken link for register for dart.

**December 13 2023 :: Developer tests and bug fixes. Tag v10.10.0**

- new developer tests to run all builds for all compilers on NSF NCAR machine
Derecho.
- removed redundant nc_check routine from utilities_mod in favor of
netcdf_utilities_mod::nc_check
- Improved default thinning options for AIRS L2 converter.

bug-fixes:

- AIRS L2 converter message prints correct number of obs.
- MOM6 model_mod .eqv. used for logical comparison to conform to Fortran standard.

**December 1 2023 :: Bringing DART documentation in accordance with NSF Policy. Tag v10.9.2**

**November 2 2023 :: QCEFF Input Table. Tag v11.1.0-alpha**

- The QCEFF input table allows for the specification of QCEFF/probit
input options, per QTY, at runtime.
- This replaces the functionality of using an algorithm_info_mod specific
to the model, which meant editing algorithm_info_mod.f90 to specify
which distribution should be used for which quantity.
- The algorithm_info_mod files for the lorenz_96_tracer_advection model
examples have been replaced with set QCF tables (all_bnrhf_qcf_table.csv,
all_eakf_qcf_table.csv, state_eakf_tracer_bnrhf_qcf_table.csv,
neg_qcf_table.csv) and can be found in lorenz_96_tracer_advection/work.
- Removed the ‘global’ version of filter_kind from assim_tools_mod.f90
and the &assim_tools_nml
