This build has a number of minor additions and changes, as well as a batch of bug fixes as usual. One of the slightly more significant changes is a special dialog when importing Construct 2 projects with invalid expressions. Due to a loophole in C2's expression validator, it could allow invalid expressions in some circumstances. Previously importing such projects would crash Construct 3. Now it shows a special dialog listing all the invalid expressions. You still have to close the project, but it gives you a clear path on what to update in your C2 project before you can import it.

The main addition in this build is for SDK developers. There's a new addon testing mode that allows you to load an addon from a local webserver instead of having to keep re-packaging a .c3addon file to test every change. This helps speed up development a lot. For more information, see the Construct 3 SDK documentation.
