**Full Changelog**: https://github.com/scikit-rf/scikit-rf/compare/v1.2.0...v1.3.0

The release 1.2.0 of scikit-rf brings many performance improvements, bug fixes as well as some new features (detailed list of changes below):

- Python version 3.7 if officially no more supported.
- The performances of `Circuit` have been highly improved (by Asachoo).
- IEEE 370 de-embedding capabilities have been extended with S-parameters quality checking in the frequency domain and fixture electrical requirements plotting. The example notebook showcases these new functionalities. (by mhuser )
- Still concerning IEEE 370, an issue with the leadin parameter is fixed and the mixed-modes plotting syntax is simplified with automatic mode subscript labels and proper impedance handling. The class architecture was reworked to minimize code duplication, type hints, and add docstrings without a major change to the API. (by mhuser )
- The documentation for NanoVNA2 and IEEE 370 has been much improved (by mxxmxn and mhuser)
- skrf's impulse response calculation are now comparable to Metas VNA Tools (by FranzForstmayr )

**Full Changelog**: https://github.com/scikit-rf/scikit-rf/compare/v1.0.0...v1.1.0

The major release 1.0.0 of scikit-rf is the result of 14 years of developement by around 80 contributors. In the recent months, the codebase and its API has been reorganized, cleaned and optimized, to provide a robust and well-tested RF/Microwave engineering package.

The version 1.0.0 does not include major changes with respect to the previous versions. This number 1.0.0 just aims to show for current and future users, that the scikit-rf package has now reached a significant level of maturity, a sufficient stable and performant state, ready for production use. It means that the developers consider scikit-rf to be ready for a widespread adoption.

Of course, scikit-rf development will continue, with new features, bug fixes, improved performances, in its subsequent versions.

Looking ahead to future release, we have releases a survey is intended for all the users of scikit-rf, in order for the developers to get some feedback, to determine what are the functionalities used the most and the less, the ones which could be improved, and to determine the directions for the future of the package. Thank you for your time in answering this survey. This should take 5 minutes and your feedback will be very useful.
