======================================================================

|

|
||||
Major changes between "less" versions 354 and 358
|
||||
|
||||
* Add -J (--status-column) option to display a status column.
|
||||
|
||||
* Add -# (--shift) option to set default horizontal shift distance.
|
||||
Default horizontal shift distance is now one-half screen width.
|
||||
|
||||
* Horizontal shifting does not shift line numbers if -N is in effect.
|
||||
|
||||
* Horizontal shifting acts as though -S were set, to avoid confusion.
