Release v1.3.0

Feature release

Bug fixes

• Fix error for BHZ when band character is empty
• Fix incorrect variable name in interpolation function of DiagData
• Fix problem in kdotpy compare trying to update a non-existent figure
• Correct transformation of some BIA terms under an in-plane rotation (kdotpy 1d with stripangle)
• Fix incorrect length of expanded overlap vectors (kdotpy 1d)

Implementation changes

• Restructure source code for parsing command-line arguments
• Remove obsolete imports as to simplify dependencies between submodules
• Reorganize and improve handling of observables
• Reorganize and improve source code for vectors and vector grids
• Improve plot functions
• No longer use columns LL1 and LL2 for transitions in full mode, add an optional column deltaLL

New features

• Calculate derivatives dH/dk and velocities as operators with the currents command-line argument
• Calculate symmetrized observables of the form {dH/dk, O}
• Option to suppress plot output (pdf files) altogether
• Option to save all eigenvalues regardless of the given energy range (set by erange)

Miscellaneous

• Julian Kuther joins the developer team
