这是在此版本中的新功能和其他重要事项变更的摘要：

this is a summary of the new features and other major changes in this release:

arm compiler
• updated to arm compiler 5.03 for latest enhancements and bug fixes:
  • improved performance on well-formed loops and switch-based fsms
  • new loop optimizations, enabled with --loop_optimization_level=2
  • for further information on features and improvements see: 
arm streamline performance analyzer
• new live view added to show performance data as it is being captured
• timeline view displays individual kernel threads under the kernel process
• timeline view allows easy restoration of auto-generated charts via the snippets menu
• includes gator version 13
• gator adds support for monitoring the performance of corelink cci-400 (cache coherent interconnect)
• gator adds support for environmental data such as temperature, voltage, power and energy within the linux kernel via the hwmon interface
• gator adds support for capturing counters from clusters independently in a big.little system
ds-5 debugger
• added os awareness for keil cmsis-rtos rtx on cortex-m and cortex-a9 devices
• added os awareness for freescale mqx rtos on arm processor-based freescale devices
• trace displays can be time-correlated within the debugger and with external tools
• support is provided for displaying the coresight global timestamp unit
• instruction and data trace from etmv4 devices (such as cortex-r7) is now supported
• altera usb-blaster is supported as a connection mechanism to altera arria v soc and cyclone v soc boards
• context menu in the debug control and trace views allows editing dtsl (debug and trace services layer) options during a debug session
• new command set/show dtsl-options can be used to access dtsl options during a debug session
• new command set/show trust-ro-sections-for-opcodes controls whether trace and disassembly can rely on data from read-only sections within any images that are loaded
• device support extended to include: altera arria v soc, altera cyclone v soc and atmel atsama5d3x
dstream/rvi
• new 4.11.0 version of firmware included
• cortex-a50 series support now also includes support for cortex-a53
• stepping speed on cortex-a cores is improved
• swd connections are supported over 38-pin mictor connector and arm and ti 14-pin jtag connectors
examples
• new jython script jython_pmu to demonstrate use of the performance monitor unit (pmu) to count elapsed cycles and user-defined events
• source code and examples for a cortex-a9 port of keil cmsis-rtos rtx are included in cmsis_rtos_rtx.zip




the following features are deprecated and might be removed in a future release:

simulation models
• cortex-a8 simulation model for emulation baseboard is deprecated
supported host platforms
• support for ubuntu desktop edition 10.04 lts is deprecated
gcc toolchain
• gcc toolchain for linux applications is removed (see the compilers section in the release notes for information about installing gcc separately

the following features are removed from this release:

examples
