## [1.1.0] - 2021-12-16
### Changed
- Updated dependencies.
- Updated to Pybricks Firmware v3.1.0:
### Changed
- Renamed new `DCMotor.dc_settings()` method to `DCMotor.settings()` ([support#536]).
### Fixed
- Fixed direction for `DriveBase.turn()` and `Drivebase.curve()` for some
arguments ([support#535]).
- Fixed `then=Stop.COAST` not working in `DriveBase` methods ([support#535]).
[support#535]: https://github.com/pybricks/support/issues/535
[support#536]: https://github.com/pybricks/support/issues/536
- Updated docs:
### Added
- Added maximum voltage setter for `DCMotor` and `Motor`.
- Documented `DriveBase.curve()` method.
### Changed
- Removed `duty` setting from `Control.limits` method.
- Removed `integral_range` setting from `Control.pid` method.
## [1.1.0-rc.1] - 2021-11-19
### Added
- Hub name setting for selecting hub name when flashing firmware ([support#52]).
### Changed
- Updated to Pybricks firmware v3.1.0c1:
### Added
- Added `DriveBase.curve()` method to drive an arc segment.
- Added `then` and `wait` arguments to `DriveBase` methods ([support#57]).
### Changed
- Dropped `integral_range` argument from `Control.pid()`. This setting was
ineffective and never used. When set incorrectly, the motor could get stuck
for certain combinations of `kp` and `ki`.
- Improved motor behavior for cases with low-speed, low-load, but high
inertia ([support#366]).
- Changed how the duty cycle limit is set for `Motor` and `DCMotor`. It is now
set as a voltage limit via a dedicated method, instead of `Motor.control`.
### Fixed
- Fixed `then=Stop.COAST` being ignored in most motor commands.
- Fixed `brake()`/`light.off()` not working on Move hub I/O port C ([support#501]).
- Fixed `Remote()` failing to connect when hub is connected to 2019 or newer
MacBooks ([support#397]).
- Fixed intermittent improper detection of hot-plugged I/O devices ([support#500]).
- A program now stops when a `Motor` is unplugged while it is running, instead
of getting in a bad state.
