this release includes support for  and  devices based on the . for using cortex-m33 and cortex-m23 a  is required.

• [arm compiler]
• arm compiler 5.06u4. refer to  for details.
• arm compiler 6.6 which supports  and  based devices. refer to  for details.
•  supports now the  including  hardware security extensions and the  and  processors.
• added cmsis-rtos v2 api which extends the cmsis-rtos v1 api by supporting the armv8-m architecture, dynamic object creation, provisions for multi-core systems, and binary compatible interface across  compliant compilers.
• added debug library variants for networking, usb, and filesystem with event recorder support.
•  enhanced emmc (embedded multimedia card) initialization robustness.
•  improved usb memory stick enumeration to cope with long timeouts after initial reset.
•  added capability to disable string for custom class interfaces.
• added support for cortex-m23 and cortex-m33 processors.
• added new component event recorder.
• [flexnet floating licenses]
• customers using flexnet floating licenses should update the flexnet license server to version 11.14.0.0. this flexnet server version is mandatory for upcoming tool releases.
• flexnet version 11.14.0.0 license server tools for windows are located in the directory ..\keil\uv4\flexnet. refer the  knowledgebase article for more information.
• [target debugging]
• updated: segger j-link driver for arm devices to version 6.10i.
