## \[1.6.1] - 2022-12-06
### Added
- start_times to measurement_description
### Changed
- measurement names do not have to be unique. A postfix makes them unique.
### Attention !!

## \[1.5.2] - 2022-08-03
### Fixed
- sequencer.get_channel_data and get_measurement_param when using play() with index
as done by core-tools.
## \[1.5.1] - 2022-08-03
### Added
- Added sequencer.plot()

- Renamed Tektronix backend 'Tektronix_5014' after refactoring:
- Faster and allow fast switching between multiple uploaded sequences.
- Amplitude output has been corrected. It is 2x previous output. Correct attenuation per channel!!
- Use sequence.play(release=False) to call play multiple times after a single upload.
- Use infinite looping when n_rep > 65535
- Added sequencer.repetition_aligment to align the duration of the sequence with an external clock or signal frequency.
(currently only implemented for Tektronix)
