Visual Environment

• Camera is panned to newly created nodes.
• Long names on the Node Searcher's list are truncated. The part of the
  name that doesn't fit in the Searcher's window is replaced with an ellipsis
  character ("…").
• Magnet Alignment algorithm is used while placing new nodes. When we
  find an available free space for a new node, the node gets aligned with the
  surrounding nodes horizontally and vertically. This helps to preserve a nice
  grid-like layout for all the nodes.
• Nodes created via the TAB key or by clicking the (+) button on the
  screen are now placed below all the selected nodes when more than one node is
  selected. (Previously, they were placed below the first node that was
  selected.) This makes it easier to achieve a compact, vertical layout of the
  graph.
• Nodes created near existing nodes via the TAB key or by dropping a
  connection are now repositioned and aligned to existing nodes. This is
  to make the resulting graph prettier and avoid overlapping. In such cases,
  created nodes will be placed below an existing node or on the bottom-left
  diagonal if there is no space underneath.
• Nodes can be added to the graph by double-clicking the output ports of
  existing nodes (or by clicking them with the right mouse button).
• Node Searcher preserves its zoom factor. The visible size of the node
  searcher and edited node is now fixed. It simplifies node editing on
  non-standard zoom levels.
• Nodes can be added to the graph by clicking (+) button on the screen.
  The button is in the bottom-left corner. Node is added at the center or pushed
  down if the center is already occupied by nodes.
• Maximum zoom factor is limited to 1.0x if IDE is not in Debug Mode.
• Debug Mode for Graph Editor can be activated/deactivated using a
  shortcut. It allows access to a set of restricted features. See
  debug-shortcuts.
• New nodes can be created by dragging and dropping a connection on the
  scene.
• Node connections can be dropped by pressing the Esc key while dragging
  them.
• Added support of source maps for JS-based visualizations.
• Fixed the alignment of newly created nodes to existing nodes with
  visualizations enabled. When applicable, new nodes are now placed below
  visualizations. (Previously, they were placed to the left of the
  visualizations.)
• Fixed histograms coloring and added a color legend.
• Lazy visualization for scatter plot.
• Fixed broken node whose expression contains non-ASCII characters.
• Fixed developer console warnings about views being created but not
  registered.
• Fixed developer console errors related to Language Server (mentioning code
  3003 and "Invalid version"), occurring during project opening and after new
  node cration.
• Fixed developer console error about failing to decode a notification
  "executionContext/visualisationEvaluationFailed"
• New Version of the Node Searcher - the Component Browser The available
  methods, atoms and functions are presented in nice, categorized view. The most
  popular tools are available at hand. The panel is unstable, and can be
  disabled with the --enable-new-component-browser=false flag.
• Fixed error handling during startup. This prevents entering IDE into a
  "zombie" state, where processes were started but not visible to user. They
  could cause issues with starting further IDE instances.
• New nodes are created in the project source when the searcher is opened and a
  new node is created.
• Proper Polyglot Vector and Array Support
• IDE uses new visualization API.
• Visualization of long textual values improved
• Selecting a suggestion from the searcher or component browser now updates the
  visualisation of the edited node to preview the results of applying the
  suggestion.
• Remove here keyword from IDE.
• Shortcut changes: Pressing Enter when no node is edited opens
  Component Browser. Entering node shortcut changed to cmd + Enter.
• Added support for scrolling by pressing and holding a mouse button on a
  scrollbar.
• Added scroll bounce animation which activates when scrolling past the
  end of scrollable content.

EnsoGL (rendering engine)

• You can change font and set letters bold in the text::Area
  component. Use the set_font and
  set_bold_bytes respectively.
• Fixed a text rendering issue in nested sublayer.
• Added a new component: Grid View. It's parametrized by Entry object,
  display them arranged in a Grid. It does not instantiate all entries, only
  those visible, and re-use created entries during scrolling thus achieving
  great performance. There are variants of grid view with selection and
  highlight, scrollbars, and both.
• Massive improvements of text rendering performance. Different text
  instances are now reusing the shape shaders and the same sprite system under
  the hood. This drastically reduces the amount of required draw calls for
  scenes with a lot of text.
• Text rendering quality improvements. Glyphs are now hinted in a better
  way. Also, additional fine-tuning is performed per font and per host operating
  system.
• Display objects can now emit and receive events in the same style as
  JavaScript DOM events. The events system implements very similar
  behavior to the one described here:
  https://javascript.info/bubbling-and-capturing.
