| |
| Deprecated in this release |
| |
| * :c:macro:`DT_ENUM_TOKEN` and :c:macro:`DT_ENUM_UPPER_TOKEN`, |

| :c:macro:`DT_STRING_TOKEN` and :c:macro:`DT_STRING_UPPER_TOKEN` |
| |
| Changes in this release |
| |
| ========================== |
| |
| Removed APIs in this release |
| |
| * Removed support for the deprecated ``DEVICE_INIT`` and ``DEVICE_AND_API_INIT`` macros. |

| Build and Infrastructure |
| ************************ |
| |
| |
| * Devicetree |
| |
| * Various compatibles had incorrect vendor prefixes in their :ref:`compatible |
| <dt-important-props>` properties; the following changes were made to fix |
| these. |
| |
| * ``nios,i2c`` is now ``altr,nios2-i2c`` |
| * ``colorway,lpd8803`` is now ``greeled,lpd8803`` |
| * ``colorway,lpd8806`` is now ``greeled,lpd8806`` |
| * ``grove,light`` is now ``seeed,grove-light`` |
| * ``grove,temperature`` is now ``seeed,grove-temperature`` |
| * ``max,max30101`` is now ``maxim,max30101`` |
| * ``ublox,sara-r4`` is now ``u-blox,sara-r4`` |
| * ``xtensa,core-intc`` is now ``cdns,xtensa-core-intc`` |
| |
| Out of tree users of these compatibles will need to update their |
| devicetrees. |
| |
| You can support multiple versions of Zephyr with one devicetree by |
| including both the old and new values in your nodes' compatible properties, |
| like this example for the LPD8803:: |
| |
| my-led-strip@0 { |
| compatible = "colorway,lpd8803", "greeled,lpd8803"; |
| ... |
| }; |

| * West (extensions) |

| Libraries / Subsystems |
| ********************** |
| |
| * Disk |
| |
| |
| * Management |
| |
| |
| * CMSIS subsystem |
| |
| |
| * Power management |
| |
| * The APIs to set/clear/check if devices are busy from a power management |
| perspective have been moved to the PM subsystem. Their naming and signature |
| has also been adjusted to follow common conventions. Below you can find the |
| equivalence list. |
| |
| * ``device_busy_set`` -> ``pm_device_busy_set`` |
| * ``device_busy_clear`` -> ``pm_device_busy_clear`` |
| * ``device_busy_check`` -> ``pm_device_is_busy`` |
| * ``device_any_busy_check`` -> ``pm_device_is_any_busy`` |
| |
| * Logging |
| |
| |
| * Random |
| |
| * xoroshiro128+ PRNG deprecated in favor of xoshiro128++ |
| |
| * Shell |
| |
| |
| * Storage |
| |
| |
| * Task Watchdog |
| |
| |
| * Tracing |
| |
| |
| * Debug |
| |
| * OS |
| |
| |
| HALs |
| **** |
| |
| * HALs are now moved out of the main tree as external modules and reside in |
| their own standalone repositories. |
| |
| |
| Trusted Firmware-m |
| ****************** |
| |
| * Renamed psa_level_1 sample to psa_crypto. Extended the use of the PSA Cryptography |
| 1.0 API in the sample code to demonstrate additional crypto functionality. |
| * Added a new sample to showcase the PSA Protecter Storage service. |
| |
| Documentation |
| ************* |
| |
| * Kconfig options need to be referenced using the ``:kconfig:`` Sphinx role. |
| Previous to this change, ``:option:`` was used for this purpose. |
| * Doxygen alias ``@config{}`` has been deprecated in favor of ``@kconfig{}``. |
