+Version 2.5.0 (2026-01-01)
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* `make install` no longer touches already installed files,
+  which may appease some packaging systems (FreeBSD ports).
+  However `make install bindir=...` and the like are no longer supported.
+* fixed clicking the "(Unnamed)" buffer in 0EB popups
+* Implemented recovery file mechanism:
+  Unsaved changes are dumped to #filename#.
+  Use n,6EJ to configure the recovery file dumping interval.
+* Fixed building on platforms with very large FILENAME_MAX (GNU/Hurd)
+* fixed rub out of file writes to non-existing symlinks
+* allow configuring the command line height using h,5EJ
+* Added ED flag 2048 to redirect Scintilla messages to the command line view:
+  enables syntax highlighting on the command line.
+* The command line macro is now managed by an ordinary Scintilla view
+  both for GTK and Curses.
+* render tabs as "TAB" (without indention) in the command-line and in
+  SciTECO macros (SciTECO lexer)
+* throw an error immediately after `nEB` if n != 0
+* ./configure --enable-static-executables now automatically pulls in static
+  libraries of libraries via pkg-config.
+* ./configure supports $CURSES_CFLAGS and $CURSES_LIBS now
+* ./configure --with-launcher=LAUNCHER can be used to run SciTECO with a launcher
+  command (e.g. wine or wine64)
+* added high-contrast color scheme (contrast.tes)
+* mention both mailing list and personal mail in `sciteco --help`
+* Work around ncurses mouse handling bugs with GNOME Terminal and Xterm.
+  This has been fixed in ncurses since version 20250913.
+* fixed parallel builds: womanpages were sometimes broken
+* Support <:O>: if a label is not found, continue execution after the go-to statement.
+  Allows to use computed gotos as select-case-like constructs.
+* bumped minimum GCC version to v8.1, Gtk to 3.24
+* bumped Scintilla to v5.5.7
+* fully support NetBSD with its native libcurses (netbsd-curses)
+* support Groff v1.19.2 as still used by default on NetBSD 10
+* fixed building on openSUSE 15.5 and 15.6
+* fix up hash-bang lines only of the scripts really installed by the current
+  `make install` invocation
+* allow messages to be of arbitrary length: fixes crashes
+* added tecat.tes to standard library: can be installed as the Git textconv filter
+* some internal refactoring and simplifications
+* Fixed serious bug with certain alternative string termination chars in commands with
+  multiple string arguments. This affected curly braces, ^A and Escape ($).
+* (!) Whitespace is now ignored in front of alternative string terminators (as in TECO-64).
+  E.g. `@I   /Hello world/` is valid now.
+* implemented the ^W command for refreshing the screen in loops, for sleeping and also the
+  CTRL+L immediate editing command for forcing a complete screen redraw
+* repl.tes: added script that reproduces the classic TECO REPL command-line.
+  This is not ready, though, as it terminates on the first error.
+* `ED&2` can be used to access the program termination flag now.
+  This can be useful for checking whether a macro has run <EX> or to cancel
+  the effect of EX.
+* Fixed using the command-line replacement register (Escape, $) in batch mode:
+  was causing assertions when entering interactive mode
+* fixed a,b,c^Uq...$: The arguments where written in the wrong (reverse) order
+* ncurses: support setting the window/tab title on XTerm-like emulators
+* if <EX> fails because of a dirty buffer, the buffer's id is now included
+  in the error message
+* FreeBSD: enable dlmalloc by default (--enable-malloc-replacement) which
+  gives a 20-25% speedup
+* Special Q-registers `$` (working directory) and the clipboard registers now
+  support the append operation (:Xq, :^Uq...), i.e. you can append (or cut-append)
+  to the clipboard
+* added topics for all colon-modified commands to the online help (`?` command)
+* (!) <nEL> (set EOL mode) now sets the buffer's dirty flag, forcing you to
+  save or discard changes
+* fixed minor memory leaks during SciTECO syntax highlighting and in case
+  of end-of-macro errors
+* The primary clipboard (`~` register) is now chosen by the 10th bit in the ED flags.
+  This allows you to use the "selection" X11 clipboard as the default backend of `~`.
+* Implemented <ER> command for reading a file into the current buffer.
+  This is a Video TECO extension.
+* <EW> now accepts a numeric argument to specify the buffer to save
+* <EF> supports a numeric buffer id now
+* sciteco(7): clarified SciTECO's policy with regards to TECO-11 and Video TECO compatibility
+* sciteco(7): minor manpage fixes
+* sciteco(7): added a help topic for booleans
+* PDCurses/Wincon: disable hardware cursor after window resize
+* Improved mouse support in PDCurses v4.5.1.
+  This is in the official Windows builds.
+* GTK: implemented --detach|-d option for detaching from controlling terminal
+* GTK: fixed scrolling on systems that only support smooth scrolling
+* GTK: monospaced sections in womanpages now respect lexer.font and variable-width
+  font is configurable via lexer.woman.font (refs #34)
+* fixed ^S/^Y for search-replacement commands
+* ^S/^Y fixed for <Gq> and <EN>
+* ^S/^Y calculates the glyph offsets earlier, so that deletions after an insert or search
+  no longer affect the results.
+  This also fixes querying ranges after <FD>.
+* added <FN> as a search-and-replace variant of <N>
+* Refactored some lexer configurations to make them more pleasurable to look at.
+  Most text should always be in the default colors.
+* SciTECO lexer: style comma, braces and two-character operators as operators
+* SciTECO lexer: now tries to avoid unnecessary restylings by styling
+  from the current line as well
+* YAML lexer: default to 2 character soft tabs
+* added LaTeX lexer config
+* added --quiet, --stdin and --stdout for easier integration into UNIX pipelines
+* Improved DEC TECO compatibility - makes SciTECO much more usable as a scripting language.
+  * (!) <nA> and <nQq> now return -1 in case the index n is out of range
+  * (!) <EI> has been repurposed and is the macro file inclusion (indirect file) command now.
+    <EM> is deprecated.
+    Pre-v2.5.0 <EI> can be replaced with `I^P`.
+  * (!) <^C> is a plain "return" command now, while <^C^C> exits from the program
+  * implemented <^B> for returning the current date
+  * implemented ^E<code> string building constructs for embedding bytes and codepoints
+    in a strtoul()-like manner
+  * support <:]q> (pop Q-Register) for getting a success/failure boolean
+  * support <==> and <===> for printing octal and hexadecimal numbers
+  * support :=/:==/:=== commands: print number without trailing linefeed
+  * Implemented the <^A> command for printing arbitrary strings.
+    You can use :^A to force raw ANSI output.
+  * implemented <:Gq> for printing the Q-Register string as a message instead of inserting it
+  * implemented the <T> (typeout) command for printing to the terminal from the current buffer
+  * implemented ^T command: allows typing by code and getting characters from stdin or the user
+  * implemented ^H command for returning the current time since midnight.
+    :^H returns the seconds since the UNIX epoch and ::^H the monotonic time in microseconds
+    (useful for benchmarking).
+  * added -v/--version and <EO> command to query the program version
+  * (!) the computed go-to command (O) is now 0-indexed and all invalid indexes and
+    empty labels are ignored
+* (!) Command-line arguments are no longer passed via the unnamed buffer,
+  but via special Q-registers ^Ax.
+  This introduces one point of incompatibility with DEC TECO.
+* new string building construct ^P disables all further string building magic
+* allow process exit status to be determined by macros
+* python lexer: fixed block comment styling
+* disallow command-line termination ($$) while editing the command-line replacement
+  register (after `{`)
+* fixed rubbing out stack operations in macro calls (was causing memory violations)
+* opener.tes: Fixed +line,column syntax
+* fnkeys.tes: support folding via F1 and clicks in the folding margin
+* implemented email and "git" lexer folding, as well as folding in womanpages and for
+  the SciTECO language lexer
+* There is an Alpine Linux package in the "community" repository now.
