Old releases

For older operating system versions, such as macOS 10.12, Windows 7 or Ubuntu 16.04 for example, all OpenBoard releases are available on GitHub

Release Notes

Version 1.7.3

Bug fixes

Tried to mitigate some audio-related issues on Debian by forcing the use of the ffmpeg backend (see Known Issues for more details on the remaining bugs).
Fixed an issue where the Windows package would not contain the correct version of OpenSSL DLLs.

Known issues

On any widget, select options (drop-down lists) won't appear in the right position. Be careful as they might sometimes appear behind the left or right palette of the Board Mode.
Reading multiple audio files, then returning to a previously played audio file within the same session, results in the audio file not being played correctly, especially with short audios. Duplicate the audio to replay it without any issue, or use alternative methods to play audio (desktop mode, letters order interactivity, online audio and video apps like PeerTube, etc.).
Some use cases remain where documents at the same level can have the same name.
An unidentified issue may occur when importing a UBX, resulting in the imported documents appearing multiple times in the document tree at the same level.

Linux

In Desktop Mode, the Gnome Dock should be set to the bottom position to work around the issue with the OpenBoard left palette being unusable from above it (cf. https://bugreports.qt.io/browse/QTBUG-81341 for more details).

Version 1.7.2

Thanks to the OpenBoard Community: many of these improvements were made possible thanks to the support of the OpenBoard community! Special thanks to GitHub contributors: letsfindaway, Vekhir, sebojolais and many others!

New Features

Added the "Snap to Grid" feature, allowing users to align elements to the lines of existing backgrounds. If no background is displayed, the default grid is used.

Improvements

Scenes are now loaded in the background to improve overall performance.
Optimized thumbnail management to reduce unnecessary heavy operations.
Exported the Axes tool when exporting a document to PDF.
Current rotation angle is now displayed for any object, including rotating selections.
The current z-index of an object is displayed when using the bring forward/send backward buttons.
It is now possible to draw on either side of the triangle, even beyond its limits.
The triangle's rotation center is now its corner instead of the 0 mark.
The gray screen borders are now transparent and adjust to the resolution of the secondary screen.
Updated from Qt 5 to Qt 6 on all supported platforms.

Bug Fixes

Fixed a bug causing a crash when an annotation was added to the first page at OpenBoard startup, and the user exited OpenBoard from the Board mode.
Fixed an issue preventing video playback on Debian.
Fixed the interactivity of the "Dice" feature.
Fixed several crashes and improved overall stability.

Known Issues

Dropdown lists of widgets may sometimes appear behind the palette in Board mode.
Rare crashes when manipulating text boxes on Ubuntu 22.04, and occasionally on macOS and Debian.
Persistent issues with playing certain local video and audio files.
Duplicate documents may appear when importing UBX files.

Linux

In Desktop mode, the Gnome Dock must be positioned at the bottom to avoid issues with OpenBoard's left palette (see QTBUG-81341 for more details).

Version 1.7.1

Important Note: Many of these changes were made possible with the help of the OpenBoard community! A big thank you to all for your support. Special thanks to GitHub contributors: letsfindaway, Vekhir and PatricCunhaforWork !

New features

added the possibility to move tools (ruler, compass, etc) using arrow keys.
added a new Latex2SVG application converting Latex formulas to SVG, that you can then drag and drop on the board. Also supports mhchem for chemistry

migrated Windows build from xpdf to poppler
improved zLevel consistency and how the users can change it. A simple click on the "Layer Up" and "Layer Down" now simply increments or decrements the zLevel of the targeted object. Long click behavior remains unchanged.

Bug fixes

Workaround for an issue related to QTBUG-79216, where dead keys were simply ignored in web widgets. The workaround fixes completely the issue on Linux, but not on macOS. You can workaround the issue by giving focus of an input of the widget and pressing Next page then previous page on the Board toolbar, or by simply reloading the page when possible.
Fixed an issue where the mask would preserve aspect ratio when using the bottom right handle to resize it.
Fixed an issue where a newly created widget would not be visible until next launch
Fixed an issue where removing from board a newly created widget would erase it from library and disk

Fixed an issue where the eraser was not working when completely inside polygon
Fixed incorrect sRGB profile and some files rights
Fixed an issue by avoiding access to uninitialized DisplayManager
Fixed ruler icons behaviors when zooming

Ubuntu 20.04

When the control screen is not the leftmost screen, the main menu will not appear where it should. This is due to a Qt bug (see https://bugreports.qt.io/browse/QTBUG-84462 for more details).

macOS

Some .mp4 videos may be playable, while others are not.

Version 1.7.0

New Features

Added the ability to mark your documents as favorites. You can then drag them from the library palette (the palette located on the right in board mode) to the board, making it faster to switch between documents. Note that each recently opened document (during your current session) is also temporarily added to the Favorites folder in the library palette, even if not marked as favorites. They will be removed when you exit OpenBoard, unless you mark them as favorites before (you can do this directly in the Favorites folder).
Added the ability to import multiple files at once.
Added a "Tips and Tricks" dialog that appears in board mode, providing basic knowledge about using OpenBoard. The dialog can also be displayed via the OpenBoard menu.
Removed the obsolete "Web Browser" application from OpenBoard.
Added the "Replace All" option in the replacement dialog when importing a UBX file.
Added options to "Export Background Grid" and "Export Background Color" in preferences.
In Board mode, the thumbnails in the left palette display the current page in "real-time".
Added the ability to start in Document mode.
UBZ documents can now be imported anywhere in the document tree.
Added the ability to hide an object on the extended screen when the object is selected (useful for editable text areas that you want to hide with a mask and edit during class without revealing their content, for example).
Added a context window asking the user what to do when dropping an object over a widget, as the intention could be to drop it inside the widget or on the board.
The internal browser has been completely reworked to use a modern Chrome-based browser engine, providing full HTML5 support. This migration comes with a redesign and some interesting additions, including:
- Better support for creating widgets from web pages and detecting integratable content on the board.
- Configurable cookie management.
- Web inspector for widget developers.
- Selecting images and PDFs from web pages and adding them to the board.
Added the ability to drag and drop or copy-paste URLs onto the board to create a widget from the dropped web page.
Redesigned display management. Through preferences, you can now organize your screens in a more user-friendly way.
Added a tool to draw Cartesian axes.
Added an option to display intermediate grid lines (5 mm).
Zoom with "Ctrl + mouse wheel". You can have more precise control of the zoom using this feature. You can also scroll the current page (up and down with the mouse wheel, left and right with Alt + mouse wheel).
Added a Camera widget to directly integrate your camera into the board.
Added the ability to choose the size of the text area by holding down the mouse click until the desired width is reached.
Added the ability to operate the main OpenBoard screen in windowed mode.
Added support for ffmpeg-5.
Added support for Qt 6.
Added support for universal package on macOS (a single version for Intel or ARM processors).

Enhancements

Added keyboard shortcuts for colors (1, 2, 3, 4, and 5).
Improved the user interface in desktop mode to make it easier for the user to see what is selected. Also reduced the time needed to hold down the left click for sub-menus to appear.
The toolbar and preferences are now usable on low-resolution devices.
Improved the management of text box height. The height is now automatically managed and adjusts to user-initiated width resizing.
Enhanced "confirm before delete" dialogues, making them more explicit about what will be deleted. Added better icons to illustrate each use case.
Display name in the tooltip for objects in the library palette.
Storage of JPEG images in their native format.
Observation of image rotation based on image metadata.
The size of the exported PDF page is now the same as the imported PDF page.
Allowing the dropping of images into subfolders of the image library.
Improved positioning of annotations.
Maintained compatibility with Qt 5.12.
Many performance improvements.

Fixed an issue where, in a network storage context, the PDF layer of a newly imported document disappeared if the document was imported on Linux.
Fixed an issue where it was impossible to resize a widget horizontally or vertically.
Fixed an issue where right-clicking on a text box would deselect it, preventing pasting clipboard content into it.
Fixed a crash where an incorrectly readable PDF prevented the export from working. A new dialog now explains to the user what is happening before returning to exporting PDF pages as detailed (heavy) images.
Fixed an issue where the user had to click "Cancel" multiple times to get the desired result.
Fixed an issue where it was not possible to change the font size in an empty text box.

Fixed an issue where an unwanted drag-and-drop could be initiated by simply clicking on a thumbnail on the left palette.
Fixed an issue where the grid size was not persistent or read if the checkered or custom background was not selected (causing the Axes tool loaded on another machine not to match the original).
Fixed an issue where an object in the right palette could be selected, but the displayed buttons did not refer to it or its current state, after a drag-and-drop, for example.
Fixed an issue where clicking on a selected element or its delegation frame would deselect it.
Fixed an issue where the Google Maps application stopped working.
Fixed an issue where it was no longer possible to drag and drop a JPEG from a Pixabay search.
Fixed several crashes.
Various issues related to interactivity have been resolved, thanks to the migration to a Chrome-based browser engine. Dropdown lists should now work correctly, and it should be possible to scroll up and down when needed.
Many corrections related to metadata management.
Exporting pages with widgets now exports a screenshot of the widget's content.
Fixed some typos.

Version 1.6.2

New Features

Added a progression bar at OpenBoard's launch.
Better handling of PDF at export :
- Restored complete support of PDF (1.0 to 1.4 versions) at export and permitted partial support of versions above (1.5 to 1.7) : a bug introduced in 1.5.2 was preventing the use of this method for versions 1.0 to 1.4. Also, previously, exported PDF pages were flattened as high resolution images, if the initial version of the PDF was > 1.4 or if an error occured during export.
- exported PDFs are now much lighter, and text in the exported PDF is searchable again.
- if an error occurs during the export, previous method (flattened images of each page) is used.

Documents tree structure

You can now create complex tree structures to organize your work. The "Untitled Documents" folder is no longer relevant and, if exists from a previous installation, can be deleted. You can adjust the size of the documents tree area by playing with the vertical splitter between it and the thumbnails area.

Sortable documents

Documents can be sorted, using the "Sort Kind" drop down list and the "Sort Order" icon beside, by creation date, modification date, or alphabetical order. A second column displays the date of creation or modification.

Icons on Folders and Documents

New icons have been added to the document tree structure to improve readability and help navigation.

Import an ubz document

The import of a ubz document is always done at its initial place in the folder hierarchy. If a document of the same name already exists there, OpenBoard displays a window to rename the imported document.

Export/Import a folder

You can now export an entire folder (including the "My Documents" folder), using the new option "Export to OpenBoard UBX" in the Export menu. The exported hierarchy is preserved at import. In this case, if documents of the same name already exist in the same places, OpenBoard displays for each of them a window for renaming the imported documents.
