GNU nano upgrading information
==============================
Visible changes since 1.2
-------------------------
* Editor Features
- Support for UTF-8.
- Moving to a specified line and column of a file, instead of just a
line (+LINE[,COLUMN]).
- Smart home key (-A).
- Creation of unique backup files in a specified directory (-C <dir>).
- Insertion of spaces instead of a tab when Tab is pressed (-E).
- The long option for -K is now --rebindkeypad.
- Regular expression searching can now be toggled when nano is built
with --enable-tiny, so -R now means something else (see below).
- Restricted mode that provides more security than -o (-R).
- Blanking of the statusbar after 1 keystroke instead of 25 (-U).
- Word searches can optionally skip over punctuation (-W).
- Workaround for Delete's acting like Backspace (-d).
- Many more options are supported in the nanorc.
- Improvements to color syntax highlighting support: case insensitive
matching, the ability to include color syntaxes in separate files,
the ability to specify background colors without foreground colors,
etc.
- Insertion of single-byte characters via Esc Esc <000-255>.
- Insertion of all characters via "Verbatim Input" mode.
- Workaround for the "NumLock glitch".
- Meta-W now repeats the last search. Wrapping is now toggled via
Meta-L.
- Replacing and spell checking only selected text.
- Indenting all marked lines with one keystroke.
- Copying text into the cutbuffer without cutting it.
- Scrolling the text up and down single lines without moving the
cursor.
- PageUp and PageDown work more smoothly when using -S.
- Scrolling the help text up and down single lines.
- Cutting all text from the current position to the end of the file
with one keystroke.
- Justifying the entire file with one keystroke.
- Justifying without removing spaces from the ends of lines.
- Unjustifying after justifying and immediately resizing.
- Going to the first or last line of the current paragraph.
- Going to the first or last line of the file without having to go to
the "Search" prompt.
- Searching for filenames in the file browser.
- Displaying spaces and tabs differently to make it easier to tell
them apart.
- Many more functions available at the statusbar prompt: moving to the
next or previous word, searching for matching brackets, "Verbatim
Input" mode, etc.
* File Handling
- Automatic adding of newlines to the ends of files without them can
now be disabled (-L).
- Converting from and to DOS/Mac file format is now toggled only at
the "Write File" prompt, via Meta-D and Meta-M, and the default file
format to save in is now set depending on what format the file was
originally in. -D now makes nano use bold text instead of reverse
video text, and Meta-D at the edit window now does a
word/line/character count. -O now makes the unused second line of
the screen part of the edit window, and Meta-O at the edit window
now toggles this behavior.
- Converting files that contain a mix of DOS and Mac format lines.
- Automatic switching on of -N with binary files has been removed, as
it causes problems with UTF-8 support.
