PhasorPy 0.7 (2025-08-22)

This is the seventh alpha release of the PhasorPy library. It contains several bug fixes, improvements, and breaking changes.

Lifetime-related functions have moved from the phasor module to the new lifetime module. The cursors and components modules have been renamed to cursor and component respectively.

The new phasor_from_component function calculates phasor coordinates from component fractions. The phasor_component_mvc function calculates mean value coordinates from phasor components. The phasor_to_lifetime_search function finds two lifetime components in multi-harmonic phasor coordinates. The signal_from_pqbin function reads TCSPC histograms from PicoQuant BIN files.

New tutorials demonstrate the multidimensional phasor approach and the programmatic generation of the PhasorPy logo.

This release supports Python 3.11 to 3.13. Wheels for Python 3.14, including free-threaded, are available for testing.
