Changelog (as of version 3.69)

Version 3.69
Prompt before Operation dialog (this appears if the option "Prompt for each item before Operation is made" is set in Edit Settings)
As well as displaying the item parameters which match the step's Conditional Argument, this also displays the pathname of the file it belongs to.
Added "Cancel" button. Allows cancellation out of currently running Edit macro.
Added "Open Score file" button. Allows the file whose current item matches the Conditional Argument to be opened up in Score or Winscore. 

Added Edit Setting "Save output file only if original is modified". This feature along with the changes to the "Prompt before Operation" dialog allow the Edit system to be used as a "Search for item" system. No Operation field is necessary in Steps, so by adding just a Conditional Argument any type of item can be searched for and the search can be cancelled once an item has been found.

Version 3.7
Select instrument numbers dialog (this appears if the option "Show instrument number delete window in transcription" is set in Optimize Settings)
You can now remove staves from a page by specifying their instrument numbers (parameter 9 values) rather than their stave numbers. If the above option is set, the usual Optimize behaviour of removing blank staves is disabled. You can either specify the instrument number staves to delete, or, by selecting the option "Delete all instrument staves except the ones specified", the instrument number staves to keep.

Amended Description fields in Macros and Steps to scroll vertically. So now there's no limit on how long your descriptions can be.

Version 3.71
Minor bug fixes.

Version 3.72
Added Append Macro button to the Edit Macro window. This allows the steps in existing macros to be appended to the macro currently being edited, thereby providing a way to combine the functionality of individual macros.

Improved code optimization.

Added Changelog to the Help menu, for easy access within the program.

Changed Text Search and Replace in Edit. No Replace text is necessary now. This allows Search to be used on its own, and in combination with the Prompt before Operation feature introduced in v.3.69.

Version 3.73
Minor bug fixes.

Version 3.74
Minor bug fixes.

Version 3.75
(Not released)

Version 3.76
New JUSTIFY function. This function allows improved note justification over Score's internal LJ in a number of ways. 
1) Score does not allow enough space to justify ledger lines correctly in tight situations. 
2) Winscore's stretched noteheads (using p20) do not adjust the space required to justify correctly.
3) Score's AFTC, AFTB, AFTK and AFTM variables provide the same amount of space before the first note/rest in a line as at the beginning of each bar. 
ScorEdit's Justify allows the space for noteheads, accidentals, ledger lines and miscellaneous other elements required for justification to be set from the Justify Settings window. The correct adjustments are made for Winscore's stretched notes to justify correctly. Justify Settings also allows extra space to be set before the first note in a line, and this space can be set wider if there is a tie/slur to the first note from the previous stave.
Justify can be run separately or as part of the Run function where it can be combined with an Edit macro, Optimize/Unoptimize and Beam angle adjustment.

New APP keyword added to Edit Step window. This keyword allows a Score file to be appended to the current one. This is particularly useful for adding headers and footers. Click on the keyword in Edit Step and select the file to append from the File Open window. Three possible switches can be added after the pathname - 
A = append new file above the staves of the current file (adjusts the stave numbers of the file to be appended)
B = append new file below the staves of the current file (adjusts the stave numbers of the current file)
T = append new file to the top stave of the current file (useful for adding headers)
(Without a switch = append new file to the bottom stave of the current file (useful for adding footers)

Minor bug fixes.

Version 3.77
Omitted justification of note flags in v.3.76 has been rectified and a variable for this added to Justify Settings/Widths.

Added new checkbox to Conditional Argument section of Edit Step dialog. The checkbox "if no item of this kind found" is for use with the APP Operation keyword only. If selected, the file specified by APP will be appended only if no items as specified in the Code No(s). and Conditional Argument fields are found. So, for instance, to add a header or footer to page 2 onwards but not to page 1, an unsuccessful search for the title text with this option checked will produce the required result.

Version 3.78
Various bug fixes to justification. Now justifies systems of more than one stave correctly. Added breakout for tight systems where there's not enough space to justify.

Version 3.79
Various bug fixes to justification. Also fix for Grace Beam library, and added more syntax checking for Edit function.
