#### 2026-09-29 *1.54*
- **Ctrl-C and SIGTERM exit in order.** The signal handler called
  `RequestExit()` (which logs and runs a callback) and then `std::exit`,
  running the static destructors under live threads. It now makes the one
  call a handler may, `UltraCanvasApplicationBase::RequestExitFromSignal()`,
  and the main loop turns it into the same shutdown as a closed window.

#### 2026-09-29 *1.53*
- **A Prolog `.pl` file is coloured as Prolog, a Perl one as Perl.** Both
  languages use `.pl`, and which highlighting a file got was left to chance.
  Texter now reads the first lines, as it already does for `.cls` and `.m`.
  A `#` line, `use`, `my` or POD means Perl; a `%` comment or a `:-` rule
  means Prolog. A file that gives no clue opens as Perl.
#### 2026-09-28 *1.52*
- **The version is in the window title** — `UltraTexter 1.52` — so a screenshot or a
  bug report says which build it came from. The number is this changelog's
  first line, as everywhere else (`cmake/UltraCanvasVersion.cmake`). With a file open it reads `UltraTexter x.y.z - <path>`.

#### 2026-09-27 *1.51*
- **The program file is `Texter` (`Texter.exe`, `Texter.app`), no longer
  `UltraCanvasTexter`.** Update shortcuts and file associations that name the
  old file. The window title and the name in the splash are still UltraTexter.
- **The splash opens in the middle of the editor window.** It used to be
  centred on the monitor, so it sat off to one side whenever the window was
  not in the middle of the screen. Both are framework changes, see
  `Docs/UltraCanvas/changelog.d/splash-centred-on-window.md`.
#### 2026-09-25 *1.50*
- **A LaTeX `.cls` is no longer coloured as VBA, an Objective-C `.m` no
  longer as MATLAB.** With R, Scala, MATLAB and VBA switched on in the
  highlighter, `.cls` and `.m` each belong to two languages. Texter now reads
  the first lines of such a file to tell them apart: `\ProvidesClass` or a `%`
  comment is LaTeX, `VERSION 1.0 CLASS` or `Attribute VB_` is VBA, `#import`
  or `@interface` is Objective-C, a `%` comment or `function` is MATLAB. A
  LaTeX or Objective-C file opens as Plain Text, since the highlighter has no
  rules for those two.
#### 2026-09-25 *1.49*
- **The markdown side toolbar is 40 px wide again, with its separators
  centred.** It had grown to half the window: the framework's toolbar builder
  kept an 800 px minimum width on every vertical toolbar (fixed in the
  framework, see `Docs/UltraCanvas/changelog.d/toolbar-builder-thickness.md`).
  Showing the toolbar also switched its layout from a flex column to block
  layout, which put the separators at the left edge while the buttons stayed
  centred. It stays a flex column now.

#### 2026-09-21 *1.48*
- **The 1.47 entry below said neither of the two things it meant.** Two
  branches wrote a 1.47 entry at the same time - the table editing work and the
  version-number change - and git merged their bullet lists without a conflict,
  splicing two sentences into each other mid-word ("is greyed's first line is
  now the", "This changelogds it"). Both bullets are restored from their own
  commits; no behaviour changed. This is the shared-version collision
  `scripts/check_changelog.py` refuses at line 1, happening one line further
  down where nothing checks it.

#### 2026-09-20 *1.47*
- **Insert Table works in a word-processing document.** The toolbar button was
  greyed out there because there was nothing behind it; it now inserts a real
  2x2 table with a header row and puts the cursor in the first cell, the same
  thing it means in a Markdown tab.
- **A Table submenu on the right-click menu**, offered only when the cursor is
  in one: insert a row above or below, a column left or right, delete the row
  or column the cursor is in (named, so "Delete Row 2 of 5" says which), merge
  with the cell to the right or below, and split a merged cell back up. Merging
  keeps the text from both cells.
- Anything that cannot be done right now is greyed rather than hidden: Split
  Cell where nothing is merged, Merge With Cell Right in the last column.
- **One version number, one place.** This changelog's first line is now the
  only place Texter's version lives: the build reads it
  (`cmake/UltraCanvasVersion.cmake`) and passes it to the sources. The
  `"0.0-dev"` fallback in `UltraCanvasTextEditor.cpp` is gone; a build
  without the definition now fails at compile time instead of reporting
  0.0-dev. `--version` printed a literal `2.0.0` of its own (`main.cpp`);
  it prints this number now.

#### 2026-09-17 *1.46*
- **Pictures inside a line of text stay there.** A logo in the middle of a
  sentence, an icon in a heading or a signature beside a sign-off used to be
  pulled out of its line and dropped below it as a paragraph of its own, which
  re-flowed everything around it. Such a picture now stays where the author put
  it, on opening, on screen and on saving.
- A picture on a line of its own is still a standalone image, as before.

#### 2026-09-16 *1.45*
- **Tables with merged cells open, display and save correctly.** A cell spanning
  several columns is drawn that wide and the cells beside it sit past it, and a
  cell spanning rows reaches down over them — previously every cell after a
  merge was drawn in the wrong place.
- **Vertically merged cells are no longer lost when you save.** Opening a
  `.odt` or `.docx` whose cells were merged downwards and saving it quietly
  un-merged them; the merge now survives the round trip in both formats.

#### 2026-09-16 *1.44*
- **Table cells can be edited in a word-processing document.** Click into a cell
  and type; **Tab** and **Shift+Tab** move between cells. Selecting, bold and
  the rest of the formatting all work inside a cell, and **Find and Replace now
  search table content**, which they skipped before.
- Enter inside a cell adds a line to that cell rather than breaking the table in
  two, and Backspace at the start of a cell steps back to the previous one
  instead of merging cells.
- Adding and removing rows and columns, merging cells, and selecting across
  several cells at once are not available yet — which is also why **Insert
  Table** stays greyed out in these documents.

#### 2026-09-15 *1.43*
- **Find, Replace and spell checking work in word-processing documents.** Both
  were unavailable when `.odt`/`.docx`/`.doc` files moved into the WYSIWYG
  editor in 1.42; this is the other half of that change.
- Ctrl+F and Ctrl+H drive the document itself. Case-sensitive and whole-word
  both apply, the match counter reads "3 of 12", and **Replace All takes one
  Ctrl+Z to undo**, not one per match. Replaced text keeps the formatting of
  what it replaced, so replacing a word inside a bold heading leaves it bold.
- Misspelled words get the same red squiggle they do in a text document, and
  right-clicking one offers the suggestions, **Add to Dictionary** and
  **Ignore** — inside the editor's own context menu, which now also carries
  Undo, Redo, Cut, Copy, Paste and Select All in these tabs.
- **Go to line** is still not offered for these documents: a word-processing
  document is made of paragraphs, not lines, and the status bar reports the
  block the caret is in.
- Find does not reach inside table cells yet, for the same reason table cells
  are not editable in place yet.

#### 2026-09-15 *1.42*
- **Word-processing documents open as themselves.** A `.odt`, `.docx` or `.doc`
  file now opens in the WYSIWYG editor (`UltraCanvasRichTextEdit`) instead of
  being converted to Markdown first. Fonts, sizes, colours, alignment and
  embedded images are what you see and what you edit, and saving writes the same
  document back out — so a 14 pt Georgia run in red survives a round trip
  instead of being flattened to whatever Markdown could spell. Bold is a state
  of the selection, not two asterisks in the text.
- The formatting toolbar works in these tabs too: the same buttons apply the
  format to the document rather than inserting markup, and they light up from
  the caret's real formatting. **Checklist** and **Insert Table** are greyed out
  there, because a word-processing document has no checkbox list item and tables
  are not yet edited in place.
- **Insert Hyperlink** asks for the address, and **Image** picks a file and
  embeds it in the document, so the picture is still there after a save.
- Undo, Redo, Cut, Copy, Paste and Select All (menu and keyboard) act on the
  document. Copy and paste keep their formatting within UltraTexter.
- **Find**, **Replace** and **Go to line** are not available in a
  word-processing tab yet, and neither is spell checking — the status bar shows
  the block the caret is in instead of a line and column.
- **Save As** from a word-processing tab to `.md`, `.html` or `.txt` converts on
  the way out; saving to the legacy `.doc` format is still refused with a note
  to use `.docx`.

#### 2026-08-28 *1.41*
- **Spell checking.** *Edit → Spelling → Check Spelling* turns it on; misspelled words get a red squiggle as you type. *Dictionary* lists every language installed on the machine, and *Recheck Document* re-runs the check after you have taught it new words. Both the on/off state and the chosen dictionary are remembered between sessions. Nothing is loaded until you first switch it on, so start-up is unchanged if you never use it.
- **A context menu in the editor.** Right-clicking the text now opens Undo, Redo, Cut, Copy, Paste and Select All — greyed out when they would do nothing — with the Spelling submenu at the bottom. Right-clicking a misspelled word puts the suggestions, **Add to Dictionary** and **Ignore** at the top of that same menu. The caret follows the right-click unless you clicked inside a selection, so Paste lands where you clicked and Cut/Copy still act on what is highlighted.
- Markdown documents are checked as prose, not as markup: fenced and indented code blocks, inline `code`, link and image targets, autolinks, inline HTML, math and YAML front matter are all left alone, while the words around them — link text and image alt text included — are still checked.
- Spell checking is skipped for a file opened in Hex/Binary view, and follows the language you pick in the status bar.
- Requires a dictionary to be installed on the system (hunspell/myspell data, or whatever enchant finds). If none is present, switching the feature on says so instead of silently doing nothing.

#### 2026-07-29 *1.40*
- Fixed **Recent Files** losing entries — most visibly the file a document was loaded from before a **Save As**. `recent_files.txt` is shared by every window and every UltraTexter process, but each window rewrote the whole file from the snapshot it read at start-up, discarding everything the others had added since. Add/remove/clear now merge with the file on disk, and the menus re-read it when they open.
- Recent file entries are stored as normalized absolute paths, so the same file opened via a relative command-line argument, a symlink or a `..` resource path is one entry instead of several — and no longer silently drops out of the list when the working directory changes.
- Recent Files entries that share a file name (what "Save As" into another folder produces) now show their folder next to the name instead of appearing twice as the same item.
- Added `Tests/RecentFilesTest.cpp` covering the Save As / multi-window scenarios.
