**August 29 2024 :: Bug fixes for shortest_time_between_assimilations and get_close_init. Tag 11.7.1**

Bug fixes:

- Prevent hang by erroring out if shortest_time_between_assimilations <=0
- Catch and error out if max_dist or max_dist_list is <=0 for 3d sphere
3d cartesian get_close_init
- Improved defaults for template model input.nml

Doc fixes:

- Removed out-of-date info about inflation flavor character strings
- Remove out-of-date info on qceff branch checkout
- GitHub template for reporting documentation issues


**August 26 2024 :: KQCEF. Tag 11.7.0**

**Note** when using NetCDF restarts, inflation files are NetCDF also. The inflation mean and inflation standard
deviation are in separate files when you use NetCDF restarts. See :doc:`./netcdf_inflation_files` for details.

DART allows users to test the impact of using multiple different types of
algorithms for filtering, inflation/deflation, and covariance localization.

DART offers numerous **filter algorithms**. These determine how the posterior
distribution is updated based on the observations and the prior ensemble. The
following table lists the filters supported in DART along with their type (set
by *filter_kind* in ``input.nml`` under the “assim_tools_nml” section):
