Hi all,

We are pleased to announce the release of Zephyr RTOS version 2.3.0.

Major enhancements with this release include:

* A new Zephyr CMake package has been introduced, reducing the need for
environment variables

* A new Devicetree API, based on hierarchical macros, has been introduced. This
new API allows the C code to access virtually all nodes and properties in a
clean, organized fashion

* The kernel timeout API has been overhauled to be flexible and configurable,
with future support for features like 64-bit and absolute timeouts in mind

* A new k_heap/sys_heap heap allocator has been introduced, with much better
performance than the existing k_mem_pool/sys_mem_pool
Zephyr now integrates with the TF-M (Trusted Firmware M) PSA-compliant
framework

* The Bluetooth Low Energy Host now supports LE Advertising Extensions

* The CMSIS-DSP library is now included and integrated

The detailed release notes can be found here:
https://github.com/zephyrproject-rtos/zephyr/releases/tag/zephyr-v2.3.0

The next release, v2.4.0, is tentatively scheduled for September 25th 2020.

I would like to thank everybody who contributed to this release, be it with code, feedback or documentation.

Thanks,

Carles

Hi all,

The second release candidate for Zephyr 2.3.0 has now been tagged (v2.3.0-rc2).

The current issue counts are:

- 1 high-priority bug
- 16 medium-priority bugs

The high-priority bug (#23364) has a PR (#25954), but a waiver to release without a fix for this particular issue has been requested, due to the invasiveness of the Pull Request and the risk of merging it this late in the release cycle. A note would be added to the release notes and a subsequent 2.3.1 would be released to address this issue.

During the days left until the release, I would encourage everybody to test thoroughly and file any issues found so that they can be fixed as quickly as possible. Additionally, there are still sections in the release notes that need filling, those can be tracked here:
https://github.com/zephyrproject-rtos/zephyr/issues/25869

The full release log can be found here:
https://github.com/zephyrproject-rtos/zephyr/releases/tag/v2.3.0-rc2

More details about Zephyr releases can found on the pages below:
https://docs.zephyrproject.org/latest/development_process/release_process.html
https://github.com/zephyrproject-rtos/zephyr/wiki/Program-Management

The final release remains scheduled for June 5th.

Thank you to everybody who contributed to this release so far!

Hi Adam. I just so happen to be adding support for the Adafruit
ItsyBitsy M4 board ATM. It's SAMD51 based which seems to be basically
the same as the SAMG55.

I've checked the UART, GPIO, SPI, and watchdog drivers so far. I'm
adding a PWM and QSPI driver, and will check the USB driver.

You'll need to create your own board definition and to create the
device tree files.

Just an FYI, working on moving pinmux for SAM0 over to DTS like I did for atmel SAM.

Also, we’re under some discussions on QSPI so good to know that you are looking at support for that as well on SAM0.

Hi all,

*************************************************
We will be using Teams instead of Zoom:
https://teams.microsoft.com/l/meetup-join/19%3ameeting_YzYzZTAzNGItOWFiMS00MDBkLTkyYmMtNzljZjkwNDVlMThm%40thread.v2/0?context=%7b%22Tid%22%3a%22686ea1d3-bc2b-4c6f-a92c-d99c5c301635%22%2c%22Oid%22%3a%2262b63b80-05d3-4465-b5a0-f04e4e156f10%22%7d
*************************************************

Today's topics:

- QSPI flash drivers:
- Should we revisit the common QSPI API? https://github.com/zephyrproject-rtos/zephyr/pull/20069
- Should it be part of the current SPI API? https://github.com/zephyrproject-rtos/zephyr/issues/17902
- If not, should we try to unify the common functionality in the multiple QSPI flash drivers?
- https://github.com/zephyrproject-rtos/zephyr/pull/25806
- https://github.com/zephyrproject-rtos/zephyr/pull/25669

- SPI JEDEC runtime support
- PR https://github.com/zephyrproject-rtos/zephyr/pull/23658

- RTC API follow-up (if the relevant people are present and there is material for discussion)
- PR: https://github.com/zephyrproject-rtos/zephyr/pull/23526

Pending additional investigation:
- Documenting API behavior in Doxygen:
- Issue: https://github.com/zephyrproject-rtos/zephyr/issues/18970
- Issue: https://github.com/zephyrproject-rtos/zephyr/issues/21061

Additional items in the "Triage" column in the GitHub project may be discussed if time permits.

Yip, looks like I jumped the gun. Sorry about that!
