  16. - add top-level "mcr" and "mrc" commands, replacing
  17. various core-specific operations
  18. - basic semihosting support
  19. ARM11
  20. - Preliminary ETM and ETB hookup
  21. - accelerated "flash erase_check"
  22. - accelerated GDB memory checksum
  23. - support "arm regs" command
  24. - can access all core modes and registers
  25. - watchpoint support
  26. Cortex-A8
  27. - support "arm regs" command

  37. Flash Layer:
  38. 'flash bank' and 'nand device' take <bank_name> as first argument.
  39. With this, flash/NAND commands allow referencing banks by name:
  40. - <bank_name>: reference the bank with its defined name
  41. - <driver_name>[.N]: reference the driver's Nth bank
  42. New 'nand verify' command to check bank against an image file.
  43. The "flash erase_address" command now rejects partial sectors;
  44. previously it would silently erase extra data.
  45. New at91sam9 NAND controller driver.
  46. Board, Target, and Interface Configuration Scripts:
  47. ARM9
  48. - ETM and ETB hookup for iMX2* targets
  49. Add $HOME/.openocd to the search path.
  50. Core Jim/TCL Scripting:
  51. New 'usage' command to provide terse command help.
  52. Improved command 'help' command output (sorted and indented).
  53. Improved command handling:
  54. - Most boolean settings now accept any of the following:
  55. on/off, enable/disable, true/false, yes/no, 1/0
  56. - More error checking and reporting.
  57. Documentation:
  58. New built-in command development documentation and primer.
  59. Build and Release:
  60. Use --enable-doxygen-pdf to build PDF developer documentation.
  61. Consider upgrading to libftdi 0.17 if you use that library; it
  62. includes bugfixes which improve FT2232H support.
  63. For more details about what has changed since the last release,
  64. see the git repository history. With gitweb, you can browse that
  65. in various levels of detail.
  66. For older NEWS, see the NEWS files associated with each release
  67. (i.e. NEWS-<version>).
