Hi,
MetPy 0.7.0 has been released:
API Changes
------------------
* The default dimension ordering for functions in `kinematics` (i.e. when
`dim_order` is not passed) has changed from "xy" to "yx". This lets more
data work out of the box with these functions, and has been warned since
0.5.1
* Renamed `h_convergence` and `v_vorticity` to `divergence` and
`vorticity`, respectively. These latter names are simpler and more
accurate. The old names are still available for old code, but are
deprecated and will be removed in 0.9.
* `convergence_vorticity` and `shearing_stretching_deformation` are
deprecated, and will be removed in 0.9. These functions existed as
performance optimizations, but new calculation internals renders them
unnecessary.
* The parameter `sblcl` for `significant_tornado` has been renamed to
`surface_based_lcl_height` to improve clarity. This only affects users who
were passing by keyword argument.
* Changed `relative_humidity_wet_psychrometric`,
`relative_humidity_from_mixing_ratio`, and
`relative_humidity_from_specific_humidity` to return values as unitless
ratios rather than percentages, for better symmetry with the rest of the
library.
Highlights
-------------
* Added our own functions for `first_derivative`, `second_derivative`,
`gradient`, and `laplacian`. These are 3 point finite difference
calculations that handle irregularly spaced grid points.
* Added function to calculate x,y grid spacing for latitude/longitude grids
* Added table of equivalencies between GEMPAK functions and Python. This is
an on-going effort to provide a resource for migrating from GEMPAK.
* Added ability to `add_timestamp` to add outlined text
* New calculations
* Thickness (using hypsometric formula)
* Geopotential to/from height
* Mixing ratio from relative humidity
* Moist static energy
* Dry static energy
