View a comprehensive history of all the changes introduced in Construct 3 since the first release.
Tween behavior: Remove "Allow Multiple" property
Expression autocomplete no longer replaces numbers with object names
XML example modified to load XML data from a project file
Array editor: cell selection is now separate from cell edit
Advanced Random: empty seed is now a random value, which is also now the default
Desktop build: fullscreen with C2 runtime debugger now works the same as browser mode or C3 runtime, fullscreening the game instead of the debugger
Drawing Canvas: remove angle actions, as the object is not supposed to be rotatable
Deprecated WindowWidth and WindowHeight expressions in the C3 runtime. These are old and confusingly named expressions that in actual fact returned the main canvas device size.
C3 runtime: deprecated rgb() expression. Use rgbEx() or rgba() instead. (Note these use values in the 0-100 range instead of 0-255)
C3 runtime: changed WindowWidth and WindowHeight expressions to return main canvas device size for compatibility with C2 projects
Expression autocomplete now scrolls suggestion to top
The delete key will now clear selection ranges in the array and dictionary editors
Multiplayer: no longer considers ICE disconnection events as fatal
Project files now cannot be named to filenames that Construct uses in exported projects to avoid conflicts
Mobile Advert: "On configuration complete" will now trigger every layout once configured
C3 runtime: improve "not supported" message
Allow editor to run without WebGL support, although Layout Views cannot be opened. This should avoid broken graphics drivers passing the startup support check but then later crashing the editor.
C3 runtime: use same maximum spritesheet size as C2 runtime to avoid higher memory usage
Previewing with no layouts open now previews the project
Use popup preview mode by default for Safari 12, since it has per-site settings that can allow popups permission to Construct 3 only
Mobile advert: user consent dialogs show "everywhere" option not currently working with the Google SDK, so it will behave as "EU and unknown" for the time being
Updated code to invoke downloads to better support Edge
C3 runtime: update Lens2 effect so magnification parameter has effect when black alpha-only image used
C3 runtime 'Worker' property now only shown if experimental features enabled in Settings
