v3.1.2

This release contains changes leading to more free heap space, faster tcp operations, faster and smaller Docker images, improved CI tests for Windows and more.

Changes

• Fix compilation of native spiffy executable.
• Linker script refactoring.
• Docker images are now based on Alpine with Cloud9 and Xtensa GCC toolchain.
• Added UDK on Windows to our CI system.
• Moved debugf strings into SPI flash to preserve heap space.
• Optional disabling of Command Executor to preserve heap and flash space.
• Unified the memanalyzer input.

And much more. All merged PRs in this release can be seen from here

Requirements

• Starting from this version having python version 2.7 or bigger is a requirement in order to be able to upload the compiled application to your device and be able to see the memory analysis.

For a complete list of changes run the following command:

git log 3.1.0..3.1.2

And last but not least this release would have been possible without the help of our fantastic contributors and community members. And again special thanks to ADiea who contributed a lot in this release and has a trove of features that promise even more improvements.

v3.1.1 Hotfix

Hotfix release based on v3.1.0 containing bug fixes for

• spiffs_mount: It was not possible to mount SpifFS automatically
• Custom LWIP compilation headers were not set correctly

For a complete list of changes run the following command:

git log 3.1.0..3.1.1

v3.1.0

This release contains major changes, new drivers and bugfixes.

Major Changes

• Switched to using the open-source code of LWIP. This means more free heap and possibility to adapt the LWIP settings according to your network setup
• Added support for SDK 2.0
• Refactored HardwareSerial for better responsiveness and speed. Allowed the use of UART1.
• Added hooks that will allow extending OTA with signed ROMs and encrypted OTA. See wiki for details.
• Better Spiffs mounting logic
• Initial support for YeeLight smart WiFi bulbs. ( #925 )
• Initial support for AM2321 I2C sensor support.

And much more. All merged PRs in this release can be seen from here

Backwards-incompatible changes

• spiffs_mount_manual() is using the actual Flash address. Before that it was using the memory-mapped address. If you used this function you should recalculate the mounting address using this formula: `new_address = (old_address - 0x40200000)
• espconn_* functions are not enabled by default. If you are using them make sure to compile your application with ENABLE_ESPCONN=1.
• HardwareSerial - there is RX buffer but if a more complex buffering is desired it has to be implemented inside the callback delegate. Also the callbacks will not receive every single character that was types but the latest one and all unread characters can be read from the buffer.
• If you use esp-alt-sdk 1.4 you should patch it in order to be able to use custom LWIP.
• With this version we officially support SDK 2.0 and 1.5. Support for 1.4 is removed.

v3.0.1

Minor bug fix version that contains the following changes:

• The master branch is our release branch. It contain now all submodules and patched sources directly applied in the source tree. This fixes issues with the release zip file (see #840 ) not containing all third-party submodules and missing the patches for them.
• Better compilations with Windows UDK (#842)
• Better documentation for Server and ServoChannel (#862)
• Fix for samples/ScreenTFT_ILI9340-ILI9341 (#865)
• Fixed compilation of Sming with custom heap based on umm_malloc (#868)

For a complete list of changes run the following command:

git log 3.0.0..3.0.1

v3.0.0 X-Mas

We are having a fantastic Christmas release full of new features, performance and stability improvements.

Let’s mention a small part of them:

• Better handling of third-party libraries. Sming is using code from other open source projects. Getting the latest version of that code used to be time consuming and error-prone process. In this version that is no longer the case. We can have the latest version of Spiffs, rBoot, axTLS, Esp-Gdbstub or Stefan Bruens PWM in seconds.
• SSL support based on axTLS v2.1+. You can now send HTTP, MQTT or Websocket messages over SSL. This means that your small devices can securely report the temperature to a remote server.
• Better fatal error reporting and support for custom crash handlers.
• Improved WebSocket support.
• Optional use of Stefan Bruens high-quality PWM library (as a drop-in replacement for the Espressif’s one)
• Optional use of Umm-Malloc heap allocation for better usage of the available heap memory and prevention against heap fragmentation problems.
• Faster SPI.
• And many small or big bug-fixes, performance and stability improvements.

For a complete list of changes run the following command:

git log 2.1.5..3.0.0

Thanks to all of you that contributed to this fantastic major release and … Merry Christmas everyone!
