+NuttX-9.0.0 Release Notes
+-------------------------
+
+This is the first release of NuttX as Apache NuttX (Incubating) and represents our first major milestone as a Podling of the Apache Software Foundation's Incubator. This release is the culmination of nearly 6 months of hard work and includes several new architectures and drivers, and numerous improvements and bug fixes to the core RTOS, drivers, and networking subsystems.
+
+   * Major Changes to Core OS
+       * Bugfixes
+          - nxsem_wait_uninterruptible() now returns if the task is canceled.
+          - Fix a bug in pthread_condwait() that was improperly re-initializing the mutex.
+          - In sched_setpriority(), fix functions called inside a DEBUGASSERT that were eliminated when assertions are disable
+
+   * Compatibility Concerns
+
+        - The configuration option CONFIG_CAN_PASS_STRUCT is now removed.  Previously, it was used (at the cost of breaking standards support) to support older versions of the SDCC compiler that couldn't pass structs/unions as functions' parameters.  A newer version of the compiler has resolved the issue.
+
+   * Major Changes to Build System
+       - Add a post-build function that allows extending the build with CPU/board-specific logic.
+       - Add build tools to simplify ZDS-II tool usage.
+       - mkexport.sh: Deal with ARCHSCRIPT containing multiple files.
+       - Various nxstyle improvements.
+
+   * Architectural Support
+       * New architecture support
+           - Add support for RISCV-64

+           - Add support for the STM32H747I-DISCO board
+           - Add Z20X board support and bootloader to upload code from the W25 flash to SRAM
+           - Add initial support for Litex with softcore CPU VexRiscV SoC
+           - Add support for the Digilent ARTY_A7 board to test the Litex port
+           - Added initial support for Sipeed Maix Bit board with Kendryte K210 processor
+           - New architectural support: ez80f92
+           - Flat address x86_64 port of Nuttx

+           - Handle size zero in umm_malloc.c and umm_realloc.c, which causes a system freeze in kernel mode.
+           - Fixed compilation issue with poll fds notification.
+           - Report POLLHUP and POLLERR in 'revents' regardless the requested 'events' set.
+    * Networking
+       - Telnet:  Fix/Refine CTRL+C to work on telnet
+       - TCP:  Fix of faulty TCP sequence increments
+       - netdb:  Fix netdb to query IPv4 and IPv6 addresses regardless the server address type
+       - Netlink sockets may be set to non-blocking
+       - Improve TUN and SLIP, refine Control+C Handling in Telnet
+       - Sockets:  Add socket MSG_DONTWAIT support
+       - Network Loopback Driver: Add a configuration option to control packet size
+       - Network IOCTLs:  Add FIONBIO network IOCTL support
+       - NFS: Support IPv4 and TCP
+       - Sockets: Add IP and TCP socket options needed by iperf3
+       - Netlink: Add support for asynchronous Netlink responses
+       - TCP: Monitor TCP_POLL/TCP_NEWDATA/TCP_BACKLOG per the request like UDP counterpart
+       - TCP: Minor design improvement to TCP delayed ACKs
+       - DNS IPv4/IPv6 Dual Host Support: When IPv4/IPv6 Dual Stack is enabled, queries both types of addresses regardless of whether the DNS server is accessed via IPv4 or IPv6. As a result, getaddrinfo() may return a mixed (IPv4/IPv6) address list.
