Breaking Changes
Changed
- Bootloader: The default app configuration is only compatible with bootloader and partition table generated from ESP-IDF V3.1 or newer. Apps that need to support OTA update on bootloaders and/or partition tables from older ESP-IDF must enable the new configuration option "App compatible with bootloader and partition table before ESP-IDF v3.1". Additionally, in ESP-IDF v3.3, CMake build system failed to append MD5 checksum to the partition table even when the option was enabled. This bug was fixed before v4.0 release. If the bootloader and partition table were initially built with CMake and IDF v3.3.x, then the compatibility option should also be enabled.
- Freertos: upgrade to 10.4.3 - rename xTaskRemoveFromUnorderedEventList
- Build System: In previous versions of CMake build system, components found in EXTRA_COMPONENT_DIRS were applied after the project's default components directory (meaning if both contained a component with same name, the EXTRA_COMPONENT_DIRS component was built). In this version, the priority is reversed and a component in the project components directory has priority.
- http2_request/sh2lib: The "sh2lib_connect" API now now take sh2lib configurations as input instead of connection uri.
- Always compile with -fno-jump-tables -fno-tree-switch-conversion by default. This could results in performance regression for code that relies heavily on this optimization. See api-guides/memory-types.rst for how to enable it for specific source files if necessary.
- partition_table: App partitions can not have empty sybtypes (need to define them).
- partition_table: Data partitions with a empty sybtypes will be ESP_PARTITION_SUBTYPE_DATA_UNDEFINED = 0x06 instead of 0.
- partition_table: otadata partition can be only with size 0x2000 and be only one in the partition table.
- ESP_HID: Now BT HID APIs event will go through BTC->BTU->HCI.
- soc: Registers APB_CTRL are renamed to SYSCON
Deprecated
- FREERTOS: xSemaphoreAltTake and xSemaphoreAltGive APIs have been deprecated.
Removed
- tools: Users with Python 3.5 or older will have to install a recent Python version
Security
- Flash Encryption: Abort if flash encryption is not enabled in hardware but app is built with relevant config
Known Issues in v4.4-beta1
- On ESP32-S3, task watchdog might be triggered when doing OTA process.
Known issues are planned to be fixed before the final v4.4 release.
