.. _zephyr_1.5: Zephyr Kernel 1.5.0 #################### The Zephyr Engineering team is glad to announce the release of Zephyr Kernel 1.5.0. This is the first release to follow the 3-month release cadence. This release includes numerous fixes and support for major features. Additional changes include support for new drivers, sensors, and boards. Major enhancements included with the release: - TCP Support - Integration of the Paho MQTT Library support with QoS - Flash Filesystem Support - Integration of the mbedTLS library for encryption - Improved BR/EDR support (for L2CAP, in particular). - Support for the Altera Nios II/f soft CPU architecture A detailed list of changes since v1.4.0 by component follows: Kernel ****** - Added nano_fifo_put_list() APIs, which allows queuing a list of elements on a nanokernel FIFO. - Removed unused memory pool structure field. - Enhanced memory pool code. Architectures ************* - ARM: Updated to include floating point registers. - Altera Nios II/f soft CPU architecture support - Internal Interrupt Controller - Avalon Timer - Avalon JTAG UART (polling mode) as default for qemu-system-nios2, and 16550 UART as default for Altera MAX10. Boards ****** - Added Nios II QEMU board. - Added configuration for Altera MAX10 FPGA. Drivers and Sensors ******************* - Sensors: Added driver for I2C HMC5883L magnetometer. - Sensors: Added driver for I2C TMP112 temperature sensor. - Sensors: Added driver for MAX44009 light sensor. - Sensors: Added driver for LPS25HB. - HAL: Updated QMSI drivers to 1.1 - Added DMA QMSI shim driver. - Added Quark SE USB device controller driver. - Added suspend/resume to QMSI drivers. - Added Guard for critical sections of the QMSI drivers. - Added Zephyr File System API. - Added driver for ENC28J60 Ethernet SPI module. Networking ********** - TCP Support - Connection handling fixes in IP stack. - Allow sending zero length user data IP packet. Network Buffers - New net_buf_simple API for light-weight on-stack (or static) buffers where a net_buf (and its associated pool) is overkill. The net_buf API now uses as an internal implementation detail net_buf_simple. - Add support for network buffer fragmentation. - Add more net_buf big endian helpers. Bluetooth ********* - Multiple fixes & improvements to the nble driver. - New API for dealing with Out of Band data (like the local address). - Various smaller fixes & improvements in many places. Build and Infrastructure ************************ - Added "qemugdb" target to start a local GDB on port 1234. - Added script to filter known issues in the build output. - Sanity: Added "-R" option to build all test with assertions. Libraries ********* - File system: Imported Open Source FAT FS 0.12a code. - Encryption: Imported mbedTLS library. - Encryption: Updated TinyCrypt library to 2.0. Documentation ************* - Fixed all the documentations warnings during build. - Fixed several typos, trademarks and grammar. - Moved all the boards documentation to the wiki. - Moved Code Contribution documentation to the wiki. - Added package "ncurses" to the list of requirements. - Updated macOS instructions. Test and Samples **************** - Samples: Replaced old debug macro to use new SYS_LOG macro. - Added TMP112 sensor application. - Added Quark SE power management sample application. - Added DMA memory to memory transfer sample. - Added sample for MAX44009 light sensor. - Added MQTT publisher and subscriber samples. - Added mbedTLS sample client.
