Breadcrumbs path fields preserve the previous path as a "ghost" 
  when going up the tree
When you navigate up the folder tree 
  the breadcrumbs path field now preserves the branches of your previous deepest 
  location in the same hierarchy as "ghost" 
  crumbs.
                
These can be very handy both 
  as a visual reminder of the location you last visited as well as letting you 
  jump back and forth between higher and lower folders in the same hierarchy. In 
  the above screenshot we have navigated from the Projects folder back 
  up the tree to the Bill folder.
Additionally, if you navigate 
  to a sibling of an ancestor path, and the new folder has the same descendant 
  hierarchy as the original ancestor, the ghost path is also 
  preserved.
                
This lets you jump 
  very quickly to the same relative spot in a folder tree - for example, moving 
  from the sub-folders of one user's profile directory to another. In this 
  screenshot we are about to navigate to the Ben folder, a sibling of 
  the ancestor 
  folder Bill.
                
The result is that the 
  previous deeper path remains as a ghost - clicking the 
  Projects crumb will return you instantly to the same folder in 
  the new hierarchy.
You can add noghostpath to the 
  Location field's arguments to disable ghost paths entirely, or instead add 
  nopreservepath if you wish to keep ghost paths when going up 
  a level but prevent them from remaining when you switch into a new directory 
  that has the same folders below it.
Status bars now belong to the file display instead of the 
  Lister
By default, status bars are now part of the file 
  display rather than the Lister. The most practical advantage of this is that 
  instead of having a single status bar at the bottom of the Lister that is 
  shared by dual file displays, each file display can now have its own status 
  bar.
                
As well as the obvious 
  advantage of being able to see both status bars at once, this also makes 
  configuration simpler. Instead of having one status bar definition for 
  single-display mode and another for dual-display, you only need the one status 
  bar definition for both.
The options on the Preferences / 
  Display / Status Bar page let you change back to the old status bar 
  appearance (a single bar attached to the bottom of the Lister), and you can 
  also combine the two (with two separate status bars side-by-side at 
  the bottom of the Lister, rather than inline with the file 
  displays).
 
The Find-as-you-type field can now search within 
  filenames
Normally the FAYT field's "find mode" only 
  searches at the start of the filename (e.g. if you typed "pr" in the 
  above folder, the only matches would be "Preferences - Directory Opus 
  (37).png" and "Preferences - Directory Opus (35).png"). If you 
  turn on the Preferences / File Displays / Find-As-You-Type / Search 
  anywhere in the filename option, typing "pr" in the above folder 
  would also match "No Progress on Taskbar.png" and "Minimize 
  Progress.png".
Priority is still given to matching at the start of 
  the filename, however, so the first match would still be "Preferences - 
  Directory Opus (37).png". Pressing Tab or 
  F3 would then step through the subsequent 
  matches.
 
Find-as-you-type matches can now be highlighted in the file 
  display
                
If you turn on the 
  Preferences / File Displays / Find-As-You-Type / Highlight 
  matches option, the file display will highlight all filenames 
  matching the entered text. You can configure the highlight color with the 
  Preferences / Display / Colors and Fonts / Files and folders - Matched 
  Text option.
The Find-as-you-type field now displays the number of 
  matches
                
At the right edge of the FAYT 
  field Opus now displays the number of filenames matching the 
  string you typed, as well as the match index of the current 
  selection.
 
The FAYT command mode now has a history
When used 
  in command mode (to run Opus or external commands), the FAYT 
  field now preserves a history of the most recently typed 
  commands.
                
Press the 
  Up or Down cursor keys to access the 
  history.
