Major Bug Fixes

Secure Boot: Fixed crash in app if signature verification fails (#6210)

Breaking Changes

BLE_Mesh: Previously if starting/stopping BLE advertising when BLE Mesh is enabled, the corresponding events will be notified through the callback registered by esp_ble_mesh_register_prov_callback(). With this MR, the function esp_ble_mesh_register_ble_callback() need to be invoked for registering the callback used for BLE coexistence related functionalities (i.e. ADV/SCAN)
esp_tls_wolfssl: Previously an API named wolfssl_tlsext_host_name was inappropriately used for domain (host) name check.
In earlier case if the domain name was different than the ISSUER field in the peer's server certificate, then the connection might have succeeded (provided skip_common_name = false).
The old API is now replaced with wolfSSL_check_domain_name, which makes wolfSSL to check if the domain name provided matches with the ISSUER name on the peer's server certificate. With this API change, wolfSSL_connect should return a fatal error in case of a domain name mismatch
esp-tls: esp-tls client connection will now return error by default in the absence of server verification option
tinyusb: The return value of tusb_init has changed from tusb_error_t to bool in the upstream tinyusb (hathach/tinyusb@d887829)
NVS Encryption: "NVS Encryption" feature is now automatically enabled whenever the Flash Encryption feature is enabled.

Future Breaking Changes

Python: Python versions 3.5 and earlier are now deprecated and a warning is printed if used for ESP-IDF. All users are encouraged to move to Python 3.6 or newer, as soon as possible. Python 3.6 or newer will be required in the future to use ESP-IDF v4.4. Python 2.7 has been End of Life since January 2020, and Python 3.5 has been End of Life since September 2020.

Known Issues

ESP32-C3 does not support BLE multiple connections.
Deep sleep power consumption on ESP32-C3 is higher than expected (currently 0.5mA).
Nimble pairing may trigger task watchdog. We can disable CONFIG_BT_NIMBLE_CRYPTO_STACK_MBEDTLS in menuconfig to workaround this issue.
Occasionally not return from Wi-Fi Mesh esp_mesh_deinit function.
ESP32-C3 Bluetooth modem sleep using external crystal cannot work in the condition of 80MHz mininum CPU frequency when Dynamic Frequency Scaling or Automatic Light Sleep is enabled.
Skip image validation when exiting deep sleep doesn't work in ESP32-S2 or single core ESP32 unless the option Enable RTC fast memory for dynamic allocations is disabled

Known issues are planned to be fixed before the final v4.3 release.

Known Issues

The esp-2020r2 toolchain has been added in this release which includes some fixes for C++ exceptions, a fix for -O2 optimization of volatile word accesses, and an improved PSRAM fix. Extended stress testing of Wi-Fi & BT coexistence with heavy PSRAM use show there is a difficult to reproduce issue with the updated PSRAM fix. It is possible to roll back to the esp-2020r1 toolchain release by running git revert --no-edit 298f23c9 in the ESP-IDF directory, then re-run the install.sh/install.bat/install.ps1 and . export.sh/export.bat/export.ps1 steps as described in the Get Started guide. This issue will be fixed in the v4.2 final release.
A new macro to call a function with a user-allocated stack has been added but is non-functional
Secure Boot is not yet supported on ESP32-S2. Will be included in the v4.2 final release.
Early boot Random Number Generation is not enabled on ESP32-S2. The Flash Encryption feature should not be used in this release, unless keys are generated on the host and burned to eFuse manually. Do not rely on any random numbers generated before Wi-Fi is enabled. Early boot RNG for ESP32-S2 will be enabled before the v4.2 final release.
SPP: Not able to use BT SPP because exception happens when init BT SPP.
Light sleep: Wi-Fi light sleep is not stable on ESP32-S2. Wi-Fi could disconnect from AP in light sleep.

v3.3.4

b64b375

ESP-IDF Release v3.3.4

Documentation for release v3.3.4 is available at https://docs.espressif.com/projects/esp-idf/en/v3.3.4/

ESP-IDF v3.3.4 is a bugfix update for ESP-IDF v3.3. IDF v4.1 is the latest stable release of ESP-IDF at time of writing.

ESP-IDF v3.3.4 will be supported until February 2022, according to the ESP-IDF Support Policy. Since ESP-IDF v4.1, each ESP-IDF major and minor release (V4.1, V4.2, etc) is supported for 30 months after the initial stable release date.

Note: This release comes soon after v3.3.3 due to a process failure, these fixes were tested as part of the v3.3.3 release but incorrectly not included in the release. The internal release process has been revised to avoid this failure repeating again.

Known Issues

The 1.22.0-96-g2852398 GCC 5.2.0 toolchain version added in this release includes an improved PSRAM fix. Extended stress testing of Wi-Fi & BT coexistence with heavy PSRAM use show there is a difficult to reproduce issue with the updated PSRAM fix. To avoid this problem it is possible to keep the toolchain supplied with ESP-IDF V3.3.2 (version 1.22.0-80-g6c4433a) and use this ESP-IDF version, despite the warning printed by the build system. This issue will be fixed in ESP-IDF V3.3.5.

v4.1

5ef1b39

ESP-IDF Release v4.1

Documentation for release v4.1 is available at https://docs.espressif.com/projects/esp-idf/en/v4.1/

ESP-IDF v4.1 is a minor update for ESP-IDF v4.0. ESP-IDF v4.1 will be supported until February 2023 in accordance with the ESP-IDF Support Policy.

Note: This is the first ESP-IDF release since the Support Policy was updated to change all ESP-IDF stable release support periods to 30 months. Previously this support period only applied to designated "Long Term Support" releases.

This is the list of changes since release v4.0:

Major New Features

Wi-Fi: Added support for Protected Management Frames (PMF)
Wi-Fi: Added SAE authentication support for WPA3 Personal
New Python-based menuconfig tool
Networking: Added new esp_netif API to manage network interfaces, replaces tcpip_adapter which is now deprecated.
Classic Bluetooth: Added support for Hands Free Profile (HFP) Audio Gateway (AG)
DTLS support in libcoap using mbedTLS (#3977)
Secure Boot V2 support (RSA based) added for ESP32 V3
Preview support for ESP32-S2 Beta SoC. This support will be replaced with ESP32-S2 SoC support in ESP-IDF v4.2. ESP32-S2 Beta firmware is not compatible with the ESP32-S2 production SoC, and not all features are supported.

Major Bug Fixes

Security fix: Fixed AP switch to adjacent channel without disconnect (-12638)
Updated toolchain fixes for PSRAM issue in ESP32 revisions prior to V3 (note: there is a known issue with this fix, see below.)

Breaking Changes

As part of the fix for -12638, the event WIFI_EVENT_STA_AUTHMODE_CHANGE has been removed. STA will now disassociate (with reason WIFI_REASON_AUTH_CHANGED) and reassociate in this case.

Known Issues

The esp-2020r2 toolchain has been added in this release which includes some fixes for C++ exceptions, a fix for -O2 optimization of volatile word accesses, and an improved PSRAM fix. Extended stress testing of Wi-Fi & BT coexistence with heavy PSRAM use show there is a difficult to reproduce issue with the updated PSRAM fix. It is possible to roll back to the esp-2020r1 toolchain release by running git revert --no-edit 298f23c9 in the ESP-IDF directory, then re-run the install.sh/install.bat/install.ps1 and . export.sh/export.bat/export.ps1 steps as described in the Get Started guide. This issue will be fixed in the v4.1.1 release.
A new macro to call a function with a user-allocated stack has been added but is non-functional
Using ADC in DMA mode does not work correctly
Can not correctly config IPv6 segmentation and reassembly from menuconfig
Nimble doesn't support non-resolvable private address
Watchdog timeout when using an RSA 4096-bit key to connect to WPA2-Enterprise (EAP-TLS) AP.
CAN driver doesn't work correctly if assertions are disabled in menuconfig
