Psychopy

Fixes:

- on macOS the long-standing issue of the **app freezing in the dock** has now been fixed [4214](https://github.com/psychopy/psychopy/issues/4214)
- smoother handling of trying to run an experiment on a computer with different mic hardware than where the experiment was created [4210](https://github.com/psychopy/psychopy/issues/4210)
- Minolta LS100/110 was not working due to broken bytes/unicode conversion [4186](https://github.com/psychopy/psychopy/issues/4186)
- ElementArray was not honouring the contrasts (contrs) parameter [4196](https://github.com/psychopy/psychopy/issues/4196)
- Code Components were giving unnecessary warning about namespace issues. Should only warn if a variable name is being _shadowed_ not if it's being _used_ [4193](https://github.com/psychopy/psychopy/issues/4193)

Bug fixes for release 2021.2. See changelog for the new features in the 2021.2 release series

- Builder outputs weren't fully honouring the `userVersion()` request, resulting in broken PsychoJS code 5f10b0a12 017c18f2f31e
- Better documentation of (high-performance) VLC movie backend
- iohub.Mouse.setPosition was not handling units correctly when given a float
- Builder boilerplate for Microphone was looking for a transcription even if none was requested 4163

Bug fixes for release 2021.2. See [changelog for the new features in the 2021.2 release series](https://psychopy.org/changelog.html#psychopy-2021-2-0)

- macOS was crashing on launch (caused by missing files from psychtoolbox stripped by macOS GateKeeper)
- added cryptography lib explicitly to requirements for pip install 267483d00
- Runner local debug of PsychoJS experiments was failing with MIME-type errors (Runner didn't know about new psychojs packaging) 4153
- extended timeout when querying Pavlovia from the app (e.g. searching for projects) 4148
- corrected reset of clock for new Button Component
- DlgFromDict was crashing if `labels` were used (in code) 4137

*Highlights:*

- Unified Eyetracker support via ioHub is now integrated into Builder for easy-to-use eyetracking studies, many improvements and a "MouseGaze" option to simulate eye movements while testing
- Mic recordings for voice responses (Python and JS)
- Transcription (speech-to-text) via Google Speech or using CMU Pocket Sphinx (free but currently on the Python lib only)
- Improved JavaScript outputs from the Builder, providing more seamless migration to web-based studies

*Compatibility Changes:*

- <span style="color:red">CHANGED: In Python the random number generators for TrialHandlers etc use an improved algorithm (PCG64) and are now indendent of each other but seeded random sequences will differ from previous versions</span>
