2020.02.07 - GNU nano 4.8 "Jaška" • When something is pasted into nano, auto-indentation is suppressed, and the paste can be undone as a whole with a single M-U. • When a lock file is encountered during startup, pressing ^C/Cancel quits nano. (Pressing 'No' just skips the file and continues.) • Shift+Meta+letter key combos can be bound with 'bind Sh-M-letter'. Making any such binding dismisses the default behavior of ignoring Shift for all Meta+letter keystrokes. • The configuration option --with-slang (to be avoided when possible) can now be used only together with --enable-tiny. • A custom nanorc file can be specified on the command line, with -f filename or --rcfile=filename.

is pressed at yesno prompt or in linter menu Benno Schulenberg (167): bindings: allow to bind shifted Meta+letter combinations with Sh-M-X bindings: allow to rebind also ^`, although it is synonymous with ^Space bindings: do not show the Full-Justify keystroke when in View mode bindings: force the first letter in a key name to uppercase build: exclude bracketed pasting from the tiny version build: exclude option '-g' when configured without browser and help build: exclude the escape sequences for F13...F16 from the tiny version build: fix compilation for --enable-{tiny,help,multibuffer} build: restrict the use of --with-slang to together with --enable-tiny bump version numbers and add a news item for the 4.8 release copyright: update the years for significantly changed files copyright: update the years for the FSF display: adjust line and column count upon a resize also when using Slang display: clear the help lines before a briefly shown warning display: don't let a message write over the second help line display: ensure the guiding stripe can be shown when not softwrapping display: exclude a bit of feedback from the tiny version display: show the cursor during suspension also when built with Slang display: skip zero-width characters on a Linux console, to avoid a mess docs: add a FAQ item about a self-compiled nano not reading /etc/nanorc docs: document the new -f/--rcfile option docs: document the new Sh-M-X format for binding <Shift+Meta+letter> docs: for the alternative bindings, rebind ^C only in the main menu docs: improve the description of which rc-files are read

sequences for F17 to F24 input: correct the escape sequence for PageUp/PageDown on Eterm/Urxvt input: Ctrl+arrow is "Esc O x" on Eterm, as on rxvt -- not "Esc o x" input: discard partial sequences that Slang produces for F17 to F24 input: do not auto-indent when something is pasted into nano from outside input: don't discard the first keystroke after a resize when using Slang input: filter out
