== Real3D Flipbook Lite – changelog (5.5 and earlier) ==

The latest release is described in readme.txt.

= 5.5 =
* New: live preview in the flipbook editor - the flipbook updates as you change settings, on desktop or phone, with a larger preview in a lightbox
* New: the Toolbar tab shows every toolbar style and icon set as a picture
* New: any toolbar button can be moved into the Tools ("More") menu
* Change: the shortcode is now in the Publish box with a Copy button; the "Preview Flipbook" button is replaced by the live preview
* Change: removed settings that had no effect
* Change: the plugin uses its own text domain, real3d-flipbook-lite, so translations from translate.wordpress.org load
* Improvement: code updates from the WordPress.org Plugin Check

= 5.4 =
* Security and stability fixes - update recommended
* Change: Import / Export is available to administrators
* Change: converting PDF links into flipbooks is now off by default - existing sites keep the setting they have; new sites can turn it on under Real3D Flipbook > Settings > Overrides
* Improvement: faster loading - the 3D engine downloads while the pages load, and the toolbar appears before the book has finished
* Improvement: the book now fills the space the toolbar leaves free instead of shrinking more than it needs to
* Improvement: side navigation arrows are round by default, matching the viewer's buttons
* Improvement: on phones a vertical swipe over the book now scrolls the page instead of dragging a page sideways
* Improvement: book height is capped at the browser window height, fixing very tall books on phones in landscape
* Change: minimal view (toolbar replaced by a single expand button on very small embeds) is now off by default
* Fix: the book was sized wrong on load, in WebGL and in fullscreen and lightbox
* Fix: book did not fit the width of narrow containers on the cover page
* Fix: swipe mode failed to start
* Fix: page flip sound on iOS - silent for the first flips, then several queued sounds firing at once

* Fix: the Help screen greeted sites that already have flipbooks as if it were a fresh install

= 5.3 =

* New: realistic page flip - the bend follows flip speed and paper hardness
* New: page corners lift on hover, click flips the page

* Improvement: much lower memory use - pages render at the size they are shown at, and pages you flip past load small
* Improvement: faster flipping - the page you land on renders first, and more pages stay loaded
