Changelog

Selytho Page Flip Creator - Version History

Version 1.4.0 Minor

2026-07-22
  • ### Added
  • - Shoppable Catalog (Pro): map the products shown on each catalog page and readers see them as clickable pills in panels beside the flipbook, with a per-flipbook choice of panel position — automatic, pinned to the sides, or below the book
  • - Catalog bookmarks (Pro): a bookmark button beside each product lets readers save items while flipping instead of leaving the catalog; saved items are listed in the site menu, so opening one never loses the rest
  • - Collapsible settings cards in the flipbook editor, with the open or closed state remembered between visits
  • - A page-change event in the viewer engine, so other code can react when the reader turns to a new spread
  • ### Changed
  • - The flipbook editor\\\'s live preview now stays in view while the settings below it are scrolled
  • - Success notices in the editor clear themselves after a few seconds instead of remaining on screen
  • - The out-of-office notice now says that auto-replies are switched off, rather than implying the whole module is inactive
  • ### Fixed
  • - Metadata overrides were never saved: two form fields shared one name, so everything typed was replaced by the previously stored values
  • - The copyright override was dropped by the save routine even when the other metadata fields saved correctly
  • - Saved metadata vanished from the editor on load, because the panel was rebuilt empty after the stored values had been rendered
  • - Special characters such as the copyright symbol were corrupted on save by an extra unescaping step
  • - Jumping to the first page, last page or a thumbnail did not record a page view, under-counting those readers in the statistics
  • - In centre-cover mode, jumping to the last page left the sideways cover offset in place, so every following spread was off-centre

Version 1.3.15 Patch

2026-07-01
  • ### Changed
  • - Pointed the Pro upgrade link at the live checkout ahead of the first public
  • release.

Version 1.3.14 Patch

2026-07-01
  • ### Changed
  • - Renamed the internal admin menu identifiers and the public shortcode to use
  • the plugin\\\'s unique prefix, removing the last non-prefixed names and avoiding
  • any possible clash with other plugins.
  • ### Removed
  • - Dropped the legacy unprefixed shortcode alias; the prefixed shortcode is now
  • the single registered tag.

Version 1.3.13 Patch

2026-06-30
  • ### Added
  • - Control bar position, mode and distance are now available to all users in the
  • free editor\\\'s Controls panel.
  • ### Changed
  • - Soft page-curl is now supplied solely by the Pro add-on. The free build no
  • longer contains any disabled or restricted soft-curl code, bringing it into
  • full trialware compliance.
  • - The primary shortcode is now the prefixed form; the original shortcode is kept
  • as a working alias so existing embeds continue to render unchanged.
  • ### Security
  • - All admin-screen request reads are now explicitly sanitised, and request data
  • passed to extension hooks is sanitised before dispatch.

Version 1.3.12 Patch

2026-06-29
  • ### Security
  • - Updated the bundled PDF rendering library off a version carrying a known
  • security advisory to the current release.
  • ### Changed
  • - Updated the bundled 3D engine library to its current release.
  • - The custom info-panel logo is now exclusively a paid-tier feature — the free
  • build contains none of its handling (no field, no save, no default, no
  • output); the free viewer shows the bundled logo and the add-on injects a
  • custom one. Completes the trialware-removal pass.
  • - Raised page-texture resolution for sharper on-screen text, automatically
  • using a lighter resolution for very large documents to cap memory.
  • ### Fixed
  • - Page rendering after the engine/library updates: pages render as crisp white
  • paper instead of a grey-tinted, soft-text appearance.
  • - The viewer no longer stalls if a single page fails to render; the remaining
  • pages continue loading.
  • > Addresses the review feedback (trialware + out-of-date libraries). No paid
  • > features ship in the free build.

Version 1.3.11 Security

2026-06-28
  • ### Security
  • - Completed the editor output-escaping pass: the remaining conditional style
  • attributes and numeric input bounds are now escaped at the point of output
  • (restructured so each attribute value passes through an escaping helper).
  • Clears the stricter no-bare-echo scan. No change to behaviour or appearance.

Version 1.3.10 Security

2026-06-28
  • ### Security
  • - Output escaping hardened across the admin screens and the front-end viewer
  • template. Every dynamic value is now escaped at the point of output (numbers,
  • attributes, and intentional markup using the appropriate escaping helper),
  • satisfying the WordPress.org review standard with annotations disabled. No
  • change to behaviour or appearance.

Version 1.3.9 Patch

2026-06-28
  • ### Changed
  • - Raised the minimum supported WordPress version to 6.2, matching the secure
  • identifier placeholder used in the view-statistics queries.
  • ### Fixed
  • - Output escaping on the editor Pro upgrade advert (logo image and purchase
  • link) is now applied at the point of output, satisfying the WordPress.org
  • review standard for escaped output.

Version 1.3.8 Patch

2026-06-28
  • ### Added
  • - Reader keyboard and mouse shortcut reference in the editor\\\'s Controls help
  • sidebar (page turn, flip, zoom, pan, and touch gestures).
  • ### Changed
  • - Info-panel book tabs now switch the displayed book in the viewer, not just
  • its metadata.
  • - Tidied a stray product label so the branding reads consistently as \\\"Selytho\\\".
  • ### Fixed
  • - Collections (multi-PDF bookshelves) no longer fail with a \\\"no PDF URL
  • provided\\\" message; a shelf with one or more books renders correctly.
  • - The editor live preview no longer overflows its frame when padding is
  • increased — it now scales the viewer to fit the preview box.

Version 1.3.7 Minor

2026-07-12
  • ### Added
  • - Free-build upgrade advert that takes the place of the editor Pro Features
  • panel, listing what the Pro add-on unlocks with a direct purchase link.
  • ### Changed
  • - The editor Pro Features panel now renders the real, enabled controls only
  • for active Pro licences. Without Pro it is replaced by the upgrade advert, so
  • no disabled or locked feature controls are ever shown in the free build.
  • - Completed the free/Pro split: all Pro feature defaults, field saving, viewer
  • output attributes, the per-flipbook sound picker, and the global Pro settings
  • are now supplied exclusively by the Pro add-on through injection hooks.
  • - Updated the bundled 3D engine library to a current maintained release.
  • ### Fixed
  • - The flipbook editor no longer errors when the Pro add-on is absent; the
  • sound-picker wiring now bails cleanly when its Pro markup is not present.
  • > Trialware-removal completion for WordPress.org compliance — the free build is
  • > fully functional on its own and contains no present-but-locked Pro features.

Version 1.3.6 Security

2026-06-20
  • ### Security
  • - View-tracking AJAX endpoint (`slyth_track`, public/nopriv) now verifies a
  • request-origin nonce issued to the viewer. The endpoint stays anonymous
  • (it must accept logged-out traffic) but no longer accepts requests without
  • a valid nonce, guarding against off-site spam.
  • ### Fixed
  • - All view-statistics queries (`slyth_views` table) now use `$wpdb->prepare()`
  • with the `%i` identifier placeholder instead of interpolating the table name.
  • - Admin sidebar and Pro-promo output now pass through `wp_kses_post()` instead
  • of being echoed raw with suppression comments.
  • > No change to viewer behaviour, tracking, or statistics — review-compliance
  • > hardening only.

Version 1.3.5 Minor

2026-06-01
  • ### Added
  • - \\\"Get Pro\\\" link on the plugins-list row, shown on the free tier only
  • - Upsell-only Pro Features presentation in the free build, with clear benefit bullets and no locked controls
  • - Product-page link on the \\\"Created with\\\" credit, consistent across the editor preview and the front end
  • - Plugin menu now stays open with all items visible while editing a flipbook
  • ### Changed
  • - Renamed the plugin to \\\"Selytho Page Flip Creator\\\", removing the restricted \\\"WP\\\" term from the name, slug and text domain
  • - Soft page-curl is now a genuine Pro-only feature: no soft-cover rendering code ships in the free build
  • - Licence activation, status and details now come entirely from the Pro add-on; the free upgrade screen is advert-only
  • - Redesigned the upgrade overlay with a taller hero image and added custom-logo and remove-branding selling points
  • ### Removed
  • - In-plugin Pro auto-installer and the free-build licence-key entry
  • - Unused bundled legacy viewer and the StPageFlip library
  • ### Fixed
  • - Flipbooks rendered as a tall, letter-boxed sliver inside block themes; constrained-layout width is now respected

Version 1.3.4

2026-05-27
  • ### Fixed
  • - Select dropdowns: `min-width` bumped to 110px so the selected option text no longer crowds the chevron arrow

Version 1.3.3

2026-05-27
  • ## Fixed
  • - Native colour pickers (`<input type=\\\"color\\\">`) were rendered as a thin line under WordPress 7.0 — restored to the proper 48Ă—30 swatch chip
  • - Select dropdowns: added a custom chevron arrow and right padding so the WP 7.0 native arrow no longer overlaps the option text

Version 1.3.2

2026-05-27
  • ### Fixed
  • - Pro Features card \\\"Upgrade\\\" button and Licence card \\\"Get Pro\\\" button — both now open the in-plugin upgrade modal instead of navigating to robsnow.eu (previous markup used `slyth-upgrade-trigger` class with `href=\\\"#\\\"`, which navigated away)

Version 1.3.0 Minor

2026-04-29
  • ### RTL Mode
  • - Full RTL rework — replaced `bookGroup.scale.x = -1` mirror hack with proper page-order reversal, correct hinge direction, and correct flip animations
  • - RTL sheets now hinge on the right; rotation goes 0 → +Ď€ (forward) matching physical right-to-left book behaviour
  • - Textures assigned in reverse order for RTL; spine shadow baked on correct (odd) pages
  • - `deformPage` curl formula uses per-sheet `rtl` flag so curl arcs in the right direction
  • - `raycastSheet` NDC x threshold inverted for RTL — unflipped pages sit on the left side of screen
  • - Drag direction corrected for RTL (`dragDir = +1`) — drag right to advance, drag left to reverse
  • - Corner click detection uses RTL-aware flipped threshold and world corner positions
  • - `onPointerUp` snap target `t` uses correct sign for RTL rotation
  • ### Controls & Layout
  • - Outside-mode controls bar height included in `syncPadding` — wrap expands to fit controls below book
  • - Outside controls centred via flex column on wrap; no longer left-aligns after fullscreen exit
  • - Fullscreen exit handler restores flex layout for outside-mode wraps
  • - All popup panels (shelf, thumbnails, more, settings) open downward when controls are positioned at top
  • ### Info Panel
  • - Tab switch now does a full HTML rebuild — show/hide field flags applied correctly for each book
  • - Logo and credit line preserved correctly after tab switch
  • ### Admin — General Book Info
  • - Logo media picker now filters to images (PNG/SVG) not PDFs
  • - Logo preview updates immediately in the info panel preview on select or clear
  • - Logo hint updated: \\\"PNG or SVG, 800px wide ideal\\\"
  • ### Collections (Bookshelf)
  • - Separate `flwp_collection` CPT registered alongside `flwp_flipbook`
  • - Switching to shelf mode when a book title/PDF is already set prompts for confirmation before discarding
  • - Save button label updates to \\\"Save Collection\\\" in shelf mode
  • - Shortcode and list page accept both post types
  • ### Engine
  • - Spine shadow CSS overlay now tracks the book correctly when panned or zoomed

Version 1.2.2 Minor

2026-04-18
  • ### Changed
  • - Languages folder added; `fliipsterwp_backend.pot` and `fliipsterwp_frontend.pot` created covering all admin and visitor-facing strings
  • - `pro/` folder structure confirmed at plugin root; loader path verified consistent with suite convention

Version 1.2.1 Minor

2026-04-13
  • ### Viewer
  • - Spine shadow restored — CSS gradient overlay, ramps in at 25% turn, peaks at 50%, fades to ~10% on land, hidden on cover page
  • - Spine shadow hidden on cover/first page, fades in smoothly on first flip
  • - Info panel now dismisses immediately on drag start (previously only on click)
  • - Settings/dev panel disabled in admin preview mode — button hidden, blur overlay removed

  • - Preview well height fixed — no longer grows when book height setting is changed
  • - Preview always renders at fixed internal height (600px) regardless of height setting
  • - Outside controls mode no longer inflates the preview well
  • - Popup panels (thumbnails, more menu) now position correctly inside the scaled preview
  • - All popup open functions corrected for CSS transform scale factor
  • ### Statistics
  • - Per-book colour palette — each fliipbook assigned a consistent colour across all charts
  • - Views bar chart and avg time bar chart now use per-book colour instead of global accent
  • - Scatter chart dots now use per-book colour for consistency
  • - Styled hover tooltips on scatter dots, views bars, and time bars — show book name + metric
  • ### Edit Page
  • - Sidebar expanded with descriptions for PDF Source, Appearance, Controls, Info Panel, and Auto Flip sections

Version 1.2.0 Major

2026-04-13
  • ### Admin / Dashboard
  • - Statistics page (`admin.php?page=fliipsterwp-stats`) — all-time totals + per-flipbook breakdown with inline bar charts and colour-coded read depth
  • - Dashboard stats overview simplified to 4 headline numbers with \\\"Full Report\\\" link
  • - Dashboard \\\"Your Fliipbooks\\\" table — added Author and Pages columns, sourced from PDF metadata saved at edit time
  • - Quick Actions sidebar — added \\\"Create Fliipbook\\\" and \\\"View Statistics\\\" buttons
  • - About sidebar — expanded with feature highlights and inline User Manual · README · Licence links
  • - Statistics submenu added to admin navigation
  • ### Viewer Settings panel (replaces Dev Settings)

  • ### Share overlay
  • - Social icons replaced with custom `_white` SVG image files
  • - WhatsApp replaced with BlueSky (`bsky.app/intent/compose`)
  • - Copy button replaced with clickable clipboard SVG icon
  • ### Bug fixes
  • - `shadowRight` div removed — was rendering a rectangle shadow over pages during flip
  • - Shelf mode → single mode toggle now repopulates the name field from the PDF filename
  • - Settings panel close button duplicate listener removed
  • - `flwp_rtl` added to `rebuildFields` selector so RTL toggle updates admin preview live
  • ### Branding

  • ### PDF metadata
  • - `pdf_author` and `pdf_pages` saved as post meta when flipbook is opened and saved in editor

  • - Pro-only fields gated server-side in `flwp_flipbook_save()`

Version 0.2.0 Major

2026-04-12
  • #### Added
  • - **Config snapshot & reset** — `FlwpWebGL._configDefaults` stores a snapshot of all
  • per-instance config values at load time; `init()` resets before applying data-attribute
  • overrides, preventing singleton pollution across admin preview rebuilds
  • - **Cover mode: centre** — `data-cover-mode=\\\"centre\\\"` shifts the book left so a single
  • cover page is centred on load; `requestAnimationFrame` initial `clampPan()` ensures
  • position applied before first interaction
  • - **Cover centre tween** — `animateCoverShift()` smoothly tweens `coverOffsetX` from
  • centred to spread on first flip, and reverses when flipping back to cover
  • - **Visibility flags** — `SHOW_ARROWS`, `SHOW_PAGENUMS`, `SHOW_DOWNLOAD`, `SHOW_ZOOM`,
  • `SHOW_PAN`, `SHOW_FULLSCREEN`, `SHOW_THUMBNAILS`, `SHOW_SOUND` read from data attributes;
  • buttons hidden and interactions gated accordingly
  • - **Container appearance** — `data-drop-shadow`, `data-corner-radius` applied to wrap
  • element in `init()`
  • - **Controls layout from data attributes** — `buildDevPanel` returns `{ applyLayout }`;
  • `init()` calls it with `data-ctrl-pos`, `data-ctrl-mode`, `data-ctrl-dist` for initial
  • controls position/mode without dev panel interaction
  • - **Credit line** — \\\"Created by FliipsterWP WordPress plugin [year]\\\" in info panel footer;
  • suppressed when `HIDE_CREDIT = true` (`data-hide-credit=\\\"true\\\"`)
  • - **Corner radius dev panel slider** — applies `borderRadius` to wrap element
  • - **`shadowRight` div** — was missing from scene setup, causing `ReferenceError` in render loop
  • #### Changed
  • - `buildDevPanel` returns `{ applyLayout(pos, mode, dist) }` for external initialisation
  • - `init()` resets all per-instance Config fields before reading dataset overrides
  • - `onPointerMove` pan handler early-exits if `C.SHOW_PAN === false`
  • - Wheel zoom gated by `C.SHOW_ZOOM`, wheel pan gated by `C.SHOW_PAN`
  • - `soundEngine.enabled` set to `false` when `C.SHOW_SOUND === false`
  • #### Fixed
  • - Cover mode centre not applying on load — `bookGroup.position` was never set until
  • first user interaction; fixed by calling `clampPan()` on init via `requestAnimationFrame`
  • - Config singleton pollution — switching cover mode in admin preview left `COVER_MODE`
  • set for subsequent rebuilds
  • - `shadowRight is not defined` ReferenceError — element was never created in scene setup

Version 0.1.3 Minor

2026-04-11
  • #### Fixed
  • - Z-order during forward flip — active sheet always renders on top via `activeSheet`
  • index tracked separately from `currentFlip`
  • - UV coordinates flipped on back geometry — left-side pages no longer mirrored
  • - `polygonOffset` added to all materials to reduce z-fighting between stacked sheets
  • - Page number display correct from first load (was showing \\\"2–3/5\\\" on cover)
  • - Page count no longer overshoots total (was showing \\\"6/5\\\" on last page)
  • - Poll loop now checks `pdfjsLib` instead of removed MOD3 library
  • #### Changed
  • - `updateZOrder()` now accepts `activeSheet` parameter instead of inferring from rotation
  • - `updatePageNum()` rewritten — shows spread format \\\"2–3 / 5\\\", handles odd page counts
  • - `updateZOrder()` only called per-frame while a flip is active (performance)

Version 0.1.2 Minor

2026-04-11
  • #### Fixed
  • - Camera now correctly fits the open book spread (2Ă—pW wide, pH tall) using proper
  • vertical/horizontal FOV calculation — tightest axis wins
  • - Book centred in viewport (was offset to right)
  • - `renderer.setPixelRatio(1)` — DPR scaling was making canvas 2Ă— container size
  • - `THREE.PlaneGeometry attributes.position undefined` — fixed by switching to three.r128.min.js
  • - Texture resize to 512Ă—512 eliminated (workaround no longer needed with r128)
  • #### Changed
  • - Replaced old bundled Three.js with `three.r128.min.js` (r128 PlaneGeometry IS a BufferGeometry)
  • - `TEX_SCALE` reverted to 1.5 (was reduced to 0.6 as workaround for 512px limit)
  • - Front and back meshes now use separate cloned geometries
  • - `deformPage()` deforms both `geoFront` and `geoBack`
  • #### Removed
  • - MOD3 library entirely — its Three.js adapter uses the legacy `geometry.vertices` API,
  • incompatible with r128 BufferGeometry

Version 0.1.1 Minor

2026-04-11
  • #### Added
  • - WordPress admin menu page (dashicons-book-alt)
  • - PDF selection via WP Media Library picker (`wp_enqueue_media`)
  • - Poll loop waits for `FlwpWebGL` + `THREE` + `pdfjsLib` before init
  • - Inline POST save in page callback (avoids headers-already-sent on redirect)
  • - First / Last page jump buttons
  • - Keyboard arrow key navigation
  • #### Fixed
  • - Scripts moved to `admin_enqueue_scripts` hook (were inside page callback — too late)
  • - Controls direction corrected (next/prev were reversed)
  • - Cover pages now use higher segment count (COVER_SEG=20) and higher hardness (COVER_HARD=10)

Version 0.1.0 Major

2026-04-10
  • #### Added
  • - Initial plugin scaffold
  • - Three.js WebGL renderer with PDF.js texture pipeline
  • - `PlaneGeometry` cylindrical curl via BufferGeometry vertex deformation
  • - Bend force formula: `1.35 Ă— sin(angle/2) / hardness^1.5`
  • - `easeInOutCubic` flip animation (FLIP_MS=900)
  • - Front/back mesh per sheet with FrontSide/BackSide materials
  • - Drag-to-flip (both directions, raycasted hit detection, 35% threshold commit/snap-back)
  • - Corner click-to-flip (bottom outer corners, NDC world-projection detection)
  • - Grab/pointer cursor feedback
  • - Spine shadow — gradient baked into back-face textures at load time
  • - Thumbnail panel — lazy-rendered grid, click to jump, spring open/close animation
  • - Zoom — scroll wheel, pinch-to-zoom, +/- buttons, 1:1 reset
  • - Pan — Alt/Cmd + drag or scroll, clamped to book extents
  • - Floating controls bar — transparent pill, configurable position (top/bottom, over/outside)
  • - Book-bound sizing — width always derived from height Ă— spread aspect ratio, never full-width
  • - No first-load flash — `visibility:hidden` until JS sets correct width
  • - Info panel — PDF metadata (title, author, subject) positioned in left slot using
  • camera world→pixel projection
  • - Z-order management for stacked sheets (`renderOrder`, `depthTest`)
  • - Resize handler
  • - Modularised into 5 JS files: `flwp-config.js`, `flwp-geometry.js`, `flwp-textures.js`,
  • `flwp-ui.js`, `flwp-book.js`

Version 1.0.0 Major

Selytho Page Flip Creator - Latest Update

v1.4.0 2026-07-22

Release Notes:

  • ### Added
  • - Shoppable Catalog (Pro): map the products shown on each catalog page and readers see them as clickable pills in panels beside the flipbook, with a per-flipbook choice of panel position — automatic, pinned to the sides, or below the book
  • - Catalog bookmarks (Pro): a bookmark button beside each product lets readers save items while flipping instead of leaving the catalog; saved items are listed in the site menu, so opening one never loses the rest
  • - Collapsible settings cards in the flipbook editor, with the open or closed state remembered between visits
  • - A page-change event in the viewer engine, so other code can react when the reader turns to a new spread
  • ### Changed
  • - The flipbook editor\\\'s live preview now stays in view while the settings below it are scrolled
  • - Success notices in the editor clear themselves after a few seconds instead of remaining on screen
  • - The out-of-office notice now says that auto-replies are switched off, rather than implying the whole module is inactive
  • ### Fixed
  • - Metadata overrides were never saved: two form fields shared one name, so everything typed was replaced by the previously stored values
  • - The copyright override was dropped by the save routine even when the other metadata fields saved correctly
  • - Saved metadata vanished from the editor on load, because the panel was rebuilt empty after the stored values had been rendered
  • - Special characters such as the copyright symbol were corrupted on save by an extra unescaping step
  • - Jumping to the first page, last page or a thumbnail did not record a page view, under-counting those readers in the statistics
  • - In centre-cover mode, jumping to the last page left the sideways cover offset in place, so every following spread was off-centre
