| 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. |

| |
| Networking |
| ********** |

| an internal implementation detail net_buf_simple. |
| - Add support for network buffer fragmentation. |
| - Add more net_buf big endian helpers. |
| |
| Bluetooth |
| ********* |

| |
| 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. |

| |
| 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. |
