Text Paragraphs scale down the font size if too much text is entered (instead of going beyond the bounds of the slide)
Images scale down if there is too much content on the same slide
Added Placeholders such as {position} or {total} to format the contents of headers and footers in the overrides
Added "Smart Templates" feature (in the document settings) which allows enabling or enabling Hyperdeck automatically trying to find the best template for the current slide based on its contents.
Allow setting "brand" logos in the top right of the slide
Add options to change the contents of the "slide number" footer
Allow deleting slides or elements from within the inspector
Temporarily removed themes but added a simple black and white one (due to theme engine changes)
Images can have a title now via 
Rewrote the way tables are rendered. They're much better now. Tables can also now expand to fit the width of the slide. Table cells can also have multiline contents.
Improved the rendering and selection of code
Allow going back through animation steps (code animations, element animations)
Reduced the visual clutter when opening a new window
Broad support for Jupyer language syntax in code blocks. So {sql} instead of sql. The { are ignore, I added this specifically because some beta testers tended to always insert code with the additional { chars.
Better support for importing media from the filesystem (movies, etc)
When exiting a presentation, select the last presented slide, so it is easy to continue at the given position
Markdown URLS are now supported. It also supports the Hyperdeck Control Scheme so you can do hyper://action/next to tap a link to jump to the next slide.
New "Jump to slide" UI that has a textual preview of the slides contents
Support for remote images. You can now display images such as 
Fix crash when editing quotes
Fix bug where the preview of a slide did not match the presentation output of the slide in certain situations (when text contained attributes, such as bold or italic)
Fix multiple bugs related to fullscreen slide display and responsive slides
Fixed a crash when modifying the author of the presentation
Fixed a bug where images were not displayed anymore if more than one document was open at the same time (two scenes, in iOS parlances)
Updated PDF export. PDF are always rendered based on the 1920x1080 default size now.
Themes keep their sizing and ratios at any resolution
Much better scrolling performance
Improved displaying of multi-line code
Fixed bug where sometimes the selection would scroll to the wrong slide when editing in the editor
Images are now sized based on their retina pixel size in a 1920x1080 sized slide. So if an image is 1920x1080 pixels wide, it will be the size of the full slide
Improved centering and alignment of images and elements
Added Video support. Videos can be played in a loop, and allow automatically starting playback but also manual playback.
Initial support for iOS 14
Playback can now be switched between responsive and non-responsive mode on the fly. Responsive means the slides always fill out the screen, non-responsive means the slides adhere to the size set for the presentation (i.e. 16:10, 3:4, etc)
Considerably improved the scrolling performance of the preview area
Added a new theme, "Blackprint" (currently in early beta as I'm trying out things)
The last slide position and editor selection is now restored when opening a document again
Added support for disabling "Responsive Slides". When disabled, the slides always have the size that is defined in the presentation size settings and do not adapt responsively to the size of the output device. This option only works when an external display is connected. It can be set in the playback dialog (accessed via the "Play" button)
Changed the displaying of the slide numbers to be less confusing. The numbers are now always displayed at the beginning of the slide, not the end.
Added exception logging to understand when events occur that - in theory - should not be happening
Added a auto paste button to the keyboard which allows quick pasting of content into the current presentation
The Preview section (right side) can now be hidden by moving the divider all the way to the right. It will automatically snap in place. A new button will appear that will allow you to snap it back into place.
Added new keyboard shortcut ⌘ + ⇧ + k to insert a new slide at the current position, not after the current slide
Added a shortcut to toggle the search bar in the editor (⌘ + f)
Added new interactive button element which allows interacting with slides or calling external services (see more info here)
The New Document screen resizes properly in split screen mode
Fixed crash that could happen when clicking on a link
Fixed an issue where inserting bold or italic before a word before a newline would insert the ending characters as the wrong location
Fixed a crash that could happen when beginning a presentation
Fixed multiple text editing crashes
Hiding the suggestion bar of the keyboard will not hide the play button anymore
Fixed a bug where the editor was cut off in certain situations when rotating to portrait mode without a hardware keyboard connected
Fixed bug that caused the position of the slides to shift when leaving the app and entering it again
Fixed a bug where the first slide continued to be selected even though others were selected
Fixed a bug that made it impossible to select the first slide in the editor in order to scroll to that position in the preview
Fixed bug where the slide numbers in the editor were wrong when settings slides to 'skipped'
Fixed a bug where images that were set as slide background images appeared twice in a slide
Fixed a bug where the selected line in a source code example would not work correctly when gradual disclosure was also being used
Fixed bug where the keyboard shortcuts did not work in the Moderator Monitor with a Magic Keyboard connected
Improved the Moderator Monitor (font size, button size) and fixed several bugs there
Generally improved support of the on-screen keyboard (particularly for the floating variant)
Fixed crash that could happen when pressing the undo button
Fixed a crash that happend when long pressing links in the editor
Fixed the layouting of images in the editor with long names, so that they don't overflow with the image preview anymore
Fixed bugs that caused presentations to not work correctly anymore when leaving the app during a presentation.
Hopefully fixed a crash that sometimes happened when navigating inspectors
Hopefully fixed a crash that sometimes happened when closing documents
Fixed bug where the text in a list entry did not respect the trailing slide margin
Fixed a bug where a X in markdown was rendered including the backticks on the slides
Fixed a bug where the highlighting in the text editor would disappear if inserting a new empty slide at the top while also having another empty slide somewhere later in the slides.
Fixed a bug where inserting a new slide via a keyboard shortcut or bottom menu would corrupt the cache, leading to severly degraded rendering performance afterwards
Fixed a bug where having a newline at the beginning of Swift source code would break the "animated lines" feature
Fixed a bug where sometimes newlines in code blocks would not appear on the slide
Fixed a bug where lists with a newline in between would break the list
Fixed a bug where the formats (bold / italic) would not disappear if the cursor position was right before the word (i.e. **|hello**)
Dragging an image or GIF from a different app into Hyperdeck will register an undo operation now
Fixed bugs which caused the contents of the bottom toolbar to be possibly wrong (say it displayed no code properties even though code was selected)
Moving the split handle for the editor and preview has better performance now
Added a bit of spacing before the "Add Slide" button in the bottom bar
Changing the font size during a presentation now affects all slides, not just the currently active one
Completely rewrote the Moderator Monitor to look better and support more interface orientations as well as split screen
Improved the colors of the tutorial screen
The bottom bar will now display remaining icons in a popover if the app is in split screen mode (or smaller)
Started collecting some usage metrics to better understand which features are used so that I can focus on what users are doing with the app
When a footnote is animated in (say in a headline, or a list), then the corresponding footnote content at the bottom appears together with the footnote reference animation
You can now have two lists side by side with alignment: left on the slide and a comment (;;) between the lists. The comment is necessary because Markdown considers newlines between lists not as separators
When using left or right alignement for a slide, the elements on both sides have the same padding now, so that they're correctly aligned if they have the same size
The loading of sample content can be disabled. The setting will be saved. So after disabling sample content the first time, the toggle control will stay disabled.
Using tab / ⇧ + tab will properly indent list entries or code lines
Nested, numbered lists work now
Inserting a new page on the last slide includes the appropriate amount of newlines
Complex slides (with lots of text) become very slow in the preview when scrolling. This will be optimized in beta 3.
Only paragraphs and formatting are allowed within blockquotes for the time being
Sometimes, when dragging / dropping an image into Hyperdeck, the app will freeze afterwards. Just switching to a different app and coming back will fix it. If you can reproduce this issue, please contact me!
Videos cannot be imported / dragged dropped yet
Redo is currently disabled
Line wrapping in source code may display odd behaviour for long names
Rearranging slides via drag and drop might lead to slighly weird resizing behaviour
The themes are still beta quality. More themes will be available in subsequent betas.
There might be color issues in the themes, I'm grateful if you point them out
Editing source code in code blocks is still work in progress, sometimes the closing '}' are not automatically inserted
The Out of Bounds warning doesn't work with all element types yet. Particularly tables are tricky.
Resizing the Preview area is a bit laggy. Especially when the slide contains code or tables. This hasn't been optimized yet.
Editing large tables can be a bit slow on older iPads
The auto format functions in tables does not work correctly when Emoji or complex unicode are inserted. This is expected behaviour as Xcode and VSCode show the same behaviour
When closing a document, it is currently always marked as 'edited' and being uploaded into iCloud again
There's currently no Spotlight support
Sometimes when selecting slides (either in the editor or in the preview) the other part does not automatically scroll to the correct slide (i.e. when selecting a slide in the preview, the editor might not automatically scroll there.). Tapping again usually works.
