 - Translation pass 2 is significantly faster by avoiding unnecessary
   searching through a kernel build/module directory tree.
 
+- When compiled against elfutils 0.142 systemtap now handles the new
+  DW_OP_call_frame_CFA generated by by GCC.
+
+- uprobes and ustack() are more robust when used on applications that
+  depend on prelinked/separate debuginfo shared libraries.
+
+- User space PROBE marks are not always found with or without separate
+  debuginfo. The .probes section itself is now always put in the main
+  elf file and marked as allocated. When when building pic code the
+  section is marked writable.  fixes the selinux memory check problems
+  seen with programs using STAP_PROBES.
+
+- statement() probes can now override "address not at start of statement"
+  errors in guru mode. They also provide alternative addresses to use
+  in non-guru mode.
+
+- The stapgraph application can generate graphs of data and events
+  emitted by systemtap scripts in real time.  Run "stapgraph
+  testsuite/systemtap.examples/general/grapher.stp" for an example of
+  graphing the system load average and keyboard events.
+  
+- Dwarf probes now show parameters and local variables in the verbose
+  listing mode (-L).
+
+- Symbol aliases are now resolved to their canonical dwarf names.  For
+  example, probing "malloc" in libc resolves to "__libc_malloc".
+
+- The syntax for dereferencing $target variables and @cast() gained new
+  capabilities:
+  - Array indexes can now be arbitrary numeric expressions.
+  - Array subscripts are now supported on pointer types.
+  - An '&' operator before a @cast or $target returns the address of the
+    final component, especially useful for nested structures.
+
+- For reading all probe variables, kernel.mark now supports $$vars and
+  $$parms, and process.syscall now supports $$vars.
+
+- The SNMP tapset provides probes and functions for many network
+  statistics.  See stapprobes.snmp(3stap) for more details.
+
+- The dentry tapset provides functions to map kernel VFS directory entries
+  to file or full path names: d_path(), d_name() and reverse_path_walk().
+
+- SystemTap now has userspace markers in its own binaries, and the stap
+  tapset provides the available probepoints and local variables.
+
+- Miscellaneous new tapset functions:
+  - pgrp() returns the process group ID of the current process
+  - str_replace() performs string replacement
