v0.0.5-beta.00 - 2026-07-20

• noPDF is now MIT licensed (LICENSE), and every bundled component's notice ships with
  the binaries. THIRD-PARTY-NOTICES.md covers PDFium (BSD-3-Clause, via the Apache-2.0
  PDFiumCore bindings and prebuilt native libraries), PDFsharp, Avalonia, SharpCompress,
  YamlDotNet, CommunityToolkit.Mvvm, System.Drawing.Common, the vendored DjvuNet, and the Inter
  font (SIL Open Font License 1.1); the release script copies it and LICENSE into Release/
  and now fails rather than producing a release without them. The vendored DjvuNet's own MIT
  notice — dropped in error when it was vendored — is restored, and VENDORING.md records what
  was modified locally and how to re-vendor from upstream.

• New documents and blank pages. :newfile opens an empty document in a new tab, at the
  size set by default_page_size in config.yaml (A4 unless you change it); it lives in memory
  until the first :save, which asks where to put it. :newpage [size] adds a blank page
  after the current one — a4, a3, a5, letter or legal, an l suffix for landscape
  (a4l), or millimetres as WxH (200x150). With no size it matches the page you're on.

• :flatten bakes annotations and filled form fields into the page content, so they stop
  being separate objects that can be selected, moved or deleted. It draws each annotation's own
  appearance, so a flattened page renders identically to the unflattened one. It's undoable
  until you save; note that it rewrites page content, so it does invalidate any existing
  signature — the status bar says so when that applies.

• DjVu opens with no external tool. A pure-managed DjVu decoder (the vendored, MIT-licensed
  DjvuNet, src/third_party/DjvuNet) is built in, so
  .djvu/.djv files work out of the box on every platform — no more "install DjVuLibre".
  If it ever meets a DjVu variant it can't handle, it still falls back to a bundled or
  installed ddjvu.

• DjVu renders correctly on photographic scans. Illuminated books and scanned plates came
  out as colour negatives, most pages came out blank, and double-page spreads came out
  narrower than single leaves. Colours are no longer wrongly inverted; render resolution is
  chosen from the factors the decoder can actually deliver (the wrong one silently produced a
  blank page); and page size now follows the DjVu's own dimensions and DPI rather than
  whatever resolution a page happened to be rendered at.

• Plain scanned DjVu opens at all. Bitonal documents — a JB2 mask with no colour layer,
  which is most scanned text — failed outright with "could not decode". They now render from
  the mask, box-filtered down so shrunken text stays antialiased and readable instead of
  losing strokes.

• Converted documents are remembered. The PDF that a DjVu or comic archive is converted
  into is cached in the temp folder, so reopening a book is instant rather than a full
  re-decode. An entry is keyed to the source's size and timestamp, so editing or replacing the
  original re-converts rather than serving a stale copy; entries expire after 30 days and the
  cache is capped at 2 GB.

• Conversion reports progress, and pages appear as they are converted. The status bar shows
  both phases — Decoding … page N of M and then Building … page N of M, which matters
  because assembling the PDF is about half the wait. The document also lays itself out as soon
  as the page geometry is known and fills each page in as it is decoded, so a long scan is
  readable from the first page instead of showing nothing until the end. Nothing scrolls or
  steals focus while this happens, and it costs no extra conversion time. The tab opens
  straight away and fills in, rather than appearing only once the whole file is converted.

• Any page can be the current one in a multi-page-across view. With :view scroll 2 (or
  scrollh), the current page was pinned to the first column: an even page could never be
  focused, :page 2 was undone as soon as it scrolled, and :newpage could only insert after
  an odd page. Scrolling now only moves the current page when it reaches a different row, and
  clicking a page makes it current.

• The command line opens over the document, not above it. It and the which-key hint were
  docked below the viewport, so opening the command line shrank the page area and the panels
  and re-laid-out the document underneath you. They now float over the bottom of the view.

• The window can be dragged by its chrome. With the title bar hidden, the status bar and
  the side panels now move the window too — anywhere that isn't a button, list, text box or
  scrollbar. Double-clicking those areas maximises and restores, as the tab strip already did.

• DjVu opens several times faster, in a fraction of the memory. Pages decode in parallel,
  the file is read once instead of per worker (which matters on network/cloud-mounted
  libraries), and photographic pages are stored as JPEG rather than PNG. A 37-page illuminated
  book went from ~9s and a 52 MB document to ~4.5s and 6 MB. Bitonal text pages stay PNG.

• Smoother zooming. Zoom (wheel or command) now resizes the pages and re-anchors the
  scroll in a single layout pass, instead of resizing and then jumping a frame later — no
  more jitter. Command zoom (:zoom, zi/zo) keeps the viewport centre put.

v0.0.4-beta.00 - 2026-07-18

• Editing a signed document is now clearly flagged. Verification says "INVALID — the
  document was changed after it was signed" (red) instead of the softer "cannot verify",
  and the signatures panel re-checks itself after a save, so it no longer keeps showing
  a stale "valid" once you've edited and saved the file.

• Switching tabs keeps each document where you left it — the scroll position and page no
  longer reset to page 1. (The shared scroll viewer resets to 0 during the swap, and that
  was overwriting the incoming tab's remembered position before it could be restored.)

• Smoother zooming. Pages now resize together and instantly (the shown image scales),
  with the crisp re-render deferred until zooming settles — instead of each page popping
  back in one at a time, which read as jittery.

• After certifying with a certificate, the tab switches to the signed file, so you're
  looking at and working on what was actually written and signed.

• :view is per tab again. The page view is recycled between tabs, and only the first
  display of a document applied its mode — so a :view command appeared to change every
  tab, and switching around left documents in each other's layouts. Each tab now re-asserts
  its own mode and scroll position when it comes forward.

• The signature watermark is visible again. It was being drawn at ~13% opacity (the
  stored mask peaks at 33/255), which is invisible on white; it's now normalised to a
  readable watermark. It also stretches to the signature frame instead of sitting in a
  square at the left.

• Signature stamps show in other viewers. The stamp carried a custom /Name, which on
  a stamp annotation names a predefined icon; viewers that honour it over the appearance
  stream drew nothing. Dropped — the appearance stream is authoritative.

• A signed document can be edited and saved again. It always could, but a failed save
  said nothing at all — :save swallowed the error and left the tab looking saved when
  nothing had been written. Failures are now reported and the tab stays dirty. Editing a
  signed file naturally invalidates its signature; :siglist says so plainly rather than
  pretending otherwise.

• The signature stamp's logo keeps its shape (centred, no longer stretched) and is
  drawn at ~50% opacity, while the name, reason and date scale to the frame you draw.

• Ctrl+Z undoes your typing inside a form field. PDFium keeps an edit history per
  field, so undo/redo now goes there while a field is focused and back to the document's
  own history once you leave it — one doesn't consume the other.

• The print dialog has a preset dropdown. Pick a saved preset to load its settings, and
  edit its name right there (renaming saves it as a new preset).

• Each release ships the default config.yaml next to the binaries — the fully
  commented one, generated from the live command list.

• Docs split: README.md is now for using noPDF; everything about building,
  the architecture and cutting releases moved to CONTRIBUTE.md.

• Fill in PDF forms. View mode (:hand) is now also form mode: click a field — or press
  f and type its label, since hints now cover form fields as well as links — and type.
  With the mouse you can click to place the caret, drag to select text inside a field, and
  toggle checkboxes/radios; the pointer shows an I-beam over a field and no longer pans the
  page when you click one. Backspace/Delete/arrows/Home/End/Tab work, Ctrl+C copies a
  field's selection, Esc leaves the field, and clicking away commits it. Filled values
  are saved into the file (they live inside PDFium until then, so they're folded back in on
  save, and before any page operation). Signature fields aren't offered for typing — those
  are for :sign.

• :w <file> re-points the tab at the file it just wrote, so :save, :copypath and
  the session all follow the new file instead of the one you sav...

• :w <file> re-points the tab at the file it just wrote, so :save, :copypath and
  the session all follow the new file instead of the one you saved away from.

• :view scroll N / :view scrollh N stay centred when you zoom instead of drifting to
  the left/top edge.

• :page next works in :view scrollh. Pages are reached sideways in that view, but it
  was aligning them vertically (so nothing moved) and tracking the current page by vertical
  position (so it never changed as you scrolled across).

• Print presets replace the single set of print defaults. :printdialog can save its
  choices as a named preset; :print <name> uses one, a bare :print uses whichever is
  marked default, and :printpreset [list | default <name> | del <name>] manages them.

• Signature verification reads externally-signed PDFs properly. The CMS is now taken
  from the /Contents string rather than the byte-range gap, so every signer and signing
  time is read even when a file's byte ranges are malformed (e.g. a document signed by
  several people with a tool that rewrites the whole file each save). The signing time
  falls back to the signature dictionary's /M date when the CMS carries none, and a
  signature whose byte range doesn't line up is reported as "cannot verify — re-saved after
  signing" instead of a bogus "invalid".

• Form fields and signature stamps now render. noPDF drew pages without their widget
  annotations, so AcroForm content — text/checkbox/radio/list/button fields, and the visible
  "Digitally signed by …" stamps — was simply missing. Pages now get PDFium's form pass
  (FPDF_FFLDraw) on top of the page render, which is the only way those are drawn. Fields
  appear exactly as the document authors them (no viewer-added highlight wash). Filling
  fields in is still read-only for now — this is the display half.

• :view scroll N no longer overlaps pages or leaves odd gaps when you zoom. The
  columns are sized to the pages at the current zoom (like the horizontal-scroll rows), so
  zooming grows them and scrolls rather than letting them collide.

• Zoom commands keep the page you're on — :zoom in/out/<pct> (and zi/zo) re-centre
  the current page instead of jumping elsewhere.

• :view full is now zoomable. Pages are laid out at their real size instead of being
  capped to the viewport, so :zoom visibly resizes them and you can pan a zoomed page;
  a hand-set zoom also survives the command bar opening (it used to snap back to fit).

• :printdialog always failed with "object reference not set to an instance of an
  object". The dialog hand-wrote an InitializeComponent, which won overload resolution
  over Avalonia's generated one — the only one that wires up the named controls, so they
  were all null. A bad page range now says so instead of quietly printing everything.

• Annotation groups are saved in the PDF (under a private /NoPdfGroup key other
  viewers ignore), nesting included — they used to live only in memory and were lost on
  save. Groups now also show in the annotations panel as a header with their members
  nested underneath.

• :siglist verifies signatures instead of just counting them, and lists them at the
  bottom of the signatures panel: signer, time, whether the signed bytes are unchanged,
  and whether the certificate chains to a trusted root (a self-signed one reads as intact
  but untrusted). Signatures noPDF writes now carry a signing time.

• :view is remembered per file, alongside the zoom and scroll position.

• Every build raises the build number, Debug included, so the version always names the
  build you're running rather than skipping a number at release time.

• Deleting an annotation stopped working after a command. Delete is a page key, and
  the command bar never handed focus back, so after :save you could still drag an
  annotation but not delete it. Focus now returns to the page, and Delete is bound
  globally so it works wherever focus happens to be.

• :view scrollh uses the whole viewport height — the rows no longer stop short of
  the top and bottom — and once zoomed in you can pan down to see the full page height.

• Changing :view keeps the page you were on instead of jumping back to page 1.

• A newly opened document opens on page 1; it used to inherit the scroll position of
  whatever was in the tab before it.

• :reload re-reads the original file, and drops the cached unsaved edits with it —
  otherwise the edits you just discarded came back the next time you opened the file.

• Clicking an annotation in the annotations panel focuses the annotation, not just
  its page: the scroll-to-page was landing last and undoing the reveal.

v0.0.3-beta.00 - 2026-07-15

Printing:

• :print actually prints. It used to hand the PDF to the default handler's
  "print" verb — which is noPDF itself — so it always failed. Pages are now
  rasterised and sent to the printer, annotations included. Windows only.
• Defaults live in the config (print_printer, print_copies, print_fit_to_page,
  print_grayscale, print_landscape); :printdialog picks them per-print and
  can save the choices back as the :print defaults.

Commands & docs:

• One command catalogue now drives :help (a landscape table per menu group:
  Command / Aliases / Keys / Description), the config file's comments, and the
  status-bar usage hint — so they can't drift apart.
• :open "path with spaces" works, and :open loads into the current tab.
• :copypath reports the path it copied.

Session & recovery:

• Autosave: unsaved edits are cached to %AppData%/NoPdf/autosave every

  "print" verb — which is noPDF itself — so it always failed. Pages are now
  rasterised and sent to the printer, annotations included. Windows only.
• Defaults live in the config (print_printer, print_copies, print_fit_to_page,
  print_grayscale, print_landscape); :printdialog picks them per-print and
  can save the choices back as the :print defaults.

Commands & docs:

• One command catalogue now drives :help (a landscape table per menu group:
  Command / Aliases / Keys / Description), the config file's comments, and the
  status-bar usage hint — so they can't drift apart.
• :open "path with spaces" works, and :open loads into the current tab.
• :copypath reports the path it copied.

Session & recovery:

• Autosave: unsaved edits are cached to %AppData%/NoPdf/autosave every
  autosave_minutes (default 5, 0 = off) and on exit, then recovered on the next
  start — still linked to the original file, so saving writes back to it.
• Lazy tabs: restoring a session no longer reads every file up front; a tab
  loads the first time you open it.

Tabs, help & bookmarks:

• Opening a file that's already open focuses its tab instead of duplicating it
  (paths are normalised; drag-drop / OS-launch / command all agree).
• :showtabs is now :tabspanel — no args toggles it; position it top,
  bottom, left or right of the view. title_buttons_in_tabs (default off)
  makes the min/close buttons ride with the panel.
• :help opens a real help document in a tab (commands, hotkeys, aliases).
• :bookmark now writes into the PDF's outline, so bookmarks are saved in the
  file and show up in other viewers; the never-persisted "My bookmarks" list is gone.
• Status bar always shows page / pages; the pages panel has a button to jump to
  the page shown in the view.
• A binding like o: ":open" pre-fills the command line instead of running it.
• Clicking an annotation in the annotations panel focuses that annotation.
• In view mode the cursor becomes a finger over links and a click follows them.

Formats & view:

• Open CBZ/CBR/CB7/CBT comic archives and DjVu documents (converted to PDF on
  load; DjVu needs DjVuLibre's ddjvu on PATH).
• View modes: :view scroll [X] (vertical scroll, X across), :view full [X]
  (only the X page(s) in focus fill the viewport — no other page can appear, at any
  zoom; scrolling turns pages) and :view scrollh [X] (horizontal scroll, X rows,
  filling each column downwards).
• The tabs panel can sit top/bottom/left/right, and the top bar collapses when it
  would otherwise be an empty strip (title_buttons_in_tabs: true).
• Annotations panel (:annots) listing every annotation; click to jump to it.

Editing & selection:

• Select is the default tool; marquee-select on empty space (drag down = enclose,
  drag up = touch). Middle-click a tab to close it.
• Nested grouping (group a group; ungroup peels one level). Shift-resize keeps aspect
  ratio. Grab-hand cursor while panning.

Editor & navigation:

• Multi-select annotations (shift-click); edit colour/width/font/opacity for the
  whole selection at once.
• Move the selection together; Shift constrains to one axis, Ctrl+drag
  duplicates.
• Group / ungroup (Ctrl+G / Ctrl+Shift+G, :group / :ungroup).
• Copy / paste annotation objects (Ctrl+C / Ctrl+V, :yank / :paste),
  shared across tabs.
• Paste a clipboard screenshot as a resizable image annotation with an
  optional frame and adjustable opacity; baked into the PDF on save.
• Follow-links hint mode (f): label every on-screen link, type the label to
  follow it (internal page jumps or web/mail links).
• Middle-mouse-button panning; Ctrl+wheel zoom now stays anchored to the cursor.
• Find (/, n, N) scrolls the match into view.

Signatures & fixes (earlier in the 0.0.2 line):

• Per-signature certificates: a Use certificate toggle with browse/generate
  (self-signed .pfx); :sign <alias> selects a preset; type the signing reason
  into the stamp and a certified signature prompts to save a signed copy.
• Signature stamp logo is transparent and left-aligned.
• Imported markup no longer gets a spurious default frame.
• Closing the last tab returns to the start page.
