- Tentatively scheduled as base version for RHEL4-U5 and RHEL5-B2.
 
- Support for paravirtualized x86_64 RHEL4 xen kernels, which require
  the use of unique hardwired kernel VM addresses, as well as a new
  user vtop function.  Without the patch, crash would report several
  read errors during invocation, and then eventually die with this
  message: "crash: cannot access phys_to_machine_mapping page".

- Fix for accessing user space stack addresses in ia64 kernels with
  3-level page tables.  This was a reqression introduced in 4.0-3.1,
  and would cause the new "ps -a" option to fail with an error message
  such as: "ps: cannot access user stack address: 60000fffffffbe28".
  Also, if the user stack address was given an the argumennt to the
  "vtop" command, it would indicate "(not mapped)".

- Implemented a new "sig -g" option, which breaks down the signal
  information into a common per-thread group section, followed by
  the signal information relevant to each task in the thread group.
  Added the capability of using the option via "foreach sig -g".

- Update to allow the entry of multiple "list -s struct.member"
  arguments, in order to display multiple members from each structure.
  Added the capability of entering a single "-s" option with multiple
  members entered in a comma-separated list, i.e., using the option
  format "-s struct.member1,member2,member3".

- The refresh_hlist_task_table() and refresh_hlist_task_table_v2()
  functions now recognize when the number of running tasks exceeds their
  internal table size, and realloc's task space as required.  Without
  the patch it would be possible to not access all tasks in a live
  system if the number of tasks increased (rather dramatically) from the
  time that the crash session started.  (anderson@redhat.com)

- Added a new hash queue tool called hq_entry_exists().  The function
  may be helpful in an extension, or future patch, to query for the
  existence of an entry in the current hash queue.  (jmoyer@redhat.com)
