Added

• Implement i2c-write-iter traits - #765 @ithinuel
• Add categories and keywords to Cargo.toml - #769 @rursprung
• Add getters to the various pad overrides - #768 @ithinuel
• Add an example for using embedded-alloc - #306 @umgefahren @jannic

• Implement defmt formatting and Debug for clocks::InitError - #751 @jannic
• Implement embedded-io Read + Write for UartPeripheral - #727 @Sympatron
• Add from_installed_program with correct shift direction - #715 @jannic
• Add derive(defmt::Format) to i2c::peripheral::I2CEvent - #726 @ithinuel
• Make PIO IRQ IDs into ZSTs - #723 @9ary
• Add RTC examples & expand RealTimeClock & ClockManager capabilities - #676 @ithinuel

• Add on-chip voltage regulator (VREG) voltage setting function - #757 @AkiyukiOkayasu
• Support for entering and exiting DORMANT mode - #701 @andrewh42

Changed

• Update lower VCO frequency limit according to datasheet update - #773 @ithinuel
• Bump MSRV to 1.75 - #761 @ithinuel
• Move on-target-tests back to the work space - #762 @ithinuel
• Set startup_delay_multiplier of XOSC to 64, and make it configurable.
  This should increase compatibility with boards where the oscillator starts up
  more slowly than on the Raspberry Pico. - #746 @jannic
• Replace asm macros by rust macros - #730 @jannic
• Update usb-device implementation - #584 @ithinuel
• Update rp2040-pac to v0.6.0 and apply required changes - #770 @AkiyukiOkayasu
• Some reorganization of ADC code, making sure that AdcPin can only
  be created for pins that can actually be used as ADC channels - #739 @jannic
• Breaking change: Clear the input-enable flag of all pins on bank 0 in Pins::new.
  They will automatically be enabled when setting a pin function, so most users
  won't be affected by that change. Notable exception: If you rely on the fact that
  PIO can read all pins as input even if the pin is not configured to the PIO function,
  you may need to set the input-enable flag manually. - #755 @jannic

Fixed

rp2040-hal v0.9.0

0.9.0 - 2023-09-01

MSRV

The Minimum-Supported Rust Version (MSRV) for this release is 1.64

Fixed

• With rust nightly and beta 1.70.0, the multi-core spawn code could get miscompiled
  due to undefined behavior in our code. This was first found in embassy (which
  uses similar code) and reported to us by @Dirbaio. - #612 @ithinuel
• Fixed embedded-hal 1.0-alpha implementation of SPI - #611 @tomgilligan
• Fixed the on-target tests - #601 @jannic

• Make sure clocks are initialized before creating a Timer - #618 @jannic
• Mark ReadTarget and WriteTarget as unsafe - #621 @jannic
• Fix typo in rom_data.rs - #675 @jlpettersson

Changed

• multicore: remove the requirement on the closure to never return - #594 @ithinuel
• Updated dependency on rp2040-boot2 to version 0.3.0. - @jannic
  This doubles the flash access speed to the value used by the C SDK by
  default. So it should usually be safe. However, if you are overclocking
  the RP2040, you might need to lower the flash speed accordingly.
• Doc: Several improvements have been made to documentation: #607 #597 #661 #633 #632 #629 #679
• DMA: Check for valid word sizes at compile time - #600 @jannic
• Use an enum for core identification. - @ithinuel
• Merge DynPin and Pin into Pin. The type class used in Pin now have a runtime variant allowing for
  the creation of uniform array of pins (eg: [Pin<DynPinId, PinFnSio, PullDown>]). - @ithinuel
• Fix miss defined ValidPinMode bound allowing any Bank0 pin to be Xip and any Qspi pin to be any
  other function (except for clock). - @ithinuel
• Use let _ = to ignore result rather than .ok(); as this gives a false sense the result is
  checked. - @ithinuel
• Reduce code repetition in i2c modules. - @ithinuel
• Rename DontInvert to Normal. - @ithinuel
• Prevent the creation of multiple instances of adc::TempSensor - @ithinuel
• Update dependency on rp2040-pac to 0.5.0 - #662 @jannic
• Migrate rp2040-hal to edition 2021 - #651 @ithinuel

• Added sio::Sio::read_bank0() -> u32 to provide single instruction multiple io read.
• Implement WriteTarget for PWM top and cc registers. - #646 @mBornand
• Add the ability to initialise the ring oscillator with a known frequency - #640 @hardiesoft
• Add ADC free-running mode & FIFO - #626 @nilclass
• Add DMA support for free-running ADC capture - #636 @nilclass
• Make SPI set_format accept frame format - #653 @NelsonAPenn
