+Changes in 2.34:
+
+* Binutils now supports debuginfod, an HTTP server for distributing
+  ELF/DWARF debugging information as well as source code. When built with
+  debuginfod, readelf and objdump can automatically query debuginfod
+  servers for separate debug files when they otherwise cannot be found.
+  To build binutils with debuginfod, pass --with-debuginfod to configure.
+  This requires libdebuginfod, the debuginfod client library. debuginfod
+  is distributed with elfutils, starting with version 0.178. For more
+  information see https://sourceware.org/elfutils.
+
 * Add --output option to the "ar" program.  This option can be used to specify
   the output directory when extracting members from an archive.
 
 * Add --keep-section option to objcopy and strip.  This option keeps the
   specified section from being removed.
 
+ * Add visualization of jumps inside a function by drawing an ascii character
+   graph between the address and the disassembler column.  Enabled via the
+   --visualize-jumps command line option for objdump.  Currently supported by
+   the x86, x86_64, and ARM targets.  The output looks something like this:
+
+  c6:  |  |     \----------> be 00 00 00 00            mov    $0x0,%esi
+  cb:  |  |           /----> 48 8b 3d 00 00 00 00      mov    0x0(%rip),%rdi        # d2 <main+0xd2>
+  d2:  |  |           |      31 c0                     xor    %eax,%eax
+  d4:  |  |           |  /-- e8 00 00 00 00            callq  d9 <main+0xd9>
+  d9:  |  |           |  \-> bf 02 00 00 00            mov    $0x2,%edi
+  de:  |  +-----------|----- e8 00 00 00 00            callq  e3 <main+0xe3>
+  e3:  |  \-----------|----> 48 89 da                  mov    %rbx,%rdx
+  e6:  |              |      be 00 00 00 00            mov    $0x0,%esi
+  eb:  |              \----- eb de                     jmp    cb <main+0xcb>
+  ed:  \-------------------> 48 8b 16                  mov    (%rsi),%rdx
+
+  Additional arguments to the --visualize-jumps option add colors to the
+  output.
