Major changes between "less" versions 358 and 371
|
||||
|
||||
* -x option can now specify multiple variable-width tab stops.
|
||||
|
||||
* -X option no longer disables keypad initialization.
|
||||
New option --no-keypad disables keypad initialization.
|
||||
|
||||
* New commands t and T step through multiple tag matches.
|
||||
Added support for "global(1)" tags
|
||||
(see http://www.gnu.org/software/global/global.html).
|
||||
|
||||
* New prompt style set by option -Pw defines the message printed
|
||||
while waiting for data in the F command.
|
||||
|
||||
* System-wide lesskey file now defaults to sysless in etc directory
|
||||
instead of .sysless in bin directory.
|
||||
Use "configure --sysconfdir=..." to change it.
|
||||
(For backwards compatibility, .sysless in bin is still recognized.)
|
||||
|
||||
* Pressing RightArrow or LeftArrow while entering a number now shifts
|
||||
the display N columns rather than editing the number itself.
|
||||
|
||||
* Status column (enabled with -J) now shows search results.
|
||||
|
||||
* Windows version sets window title.
|
||||
|
||||
* Default LESSCHARSET for MS-DOS versions is now "dos".
|
||||
|
||||
* Improved performance in reading very large files.
|
||||
|
||||
* Eliminated some dependencies on file offets being 32 bits.
|
||||
|
||||
* Fixed problems when viewing files with very long lines.
|
||||
|
||||
* Fixed overstriking in UTF-8 mode, and overstriking tabs.
|
||||
|
||||
* Improved horizontal shifting of text using -R option with ANSI color.
|
||||
|
||||
* Some fixes for EBCDIC systems.
|
||||
|
||||
* Some fixes for OS/2 systems.

|
||||
======================================================================
|
||||
|
||||
Major changes between "less" versions 354 and 358
|
||||
|
||||
* Add -J (--status-column) option to display a status column.
