Introducing version 0.4

[MuTsunTsai]

Hello to all users of BP Studio! I hereby proudly announce that version 0.4 is now officially released. The main focus of this version includes:

Performance is greatly improved, with project opening speed and rendering speed up to 3x faster.

Version 0.4 made many fundamental changes in the core to make this happen, including improved data structure, faster algorithms, multiple threads, and improvement on the Shrewd framework. Now the dragging of components will be significantly smoother, and thus the app is more capable of creating larger scale projects.
There are still large room for further performance improvements, but those will require even greater changes in the core of BP Studio, and I will leave those to the future version.

The new Edit menu, with undo/redo features (up to 30 steps).

I've implemented both command pattern and memento pattern in programming to make such feature possible. As a bonus, the "unsaved changes" warning is also now more accurately reflect whether the design has actually changed since last saving.

Two new locales: 简体中文, Español.

Both these are among the greatest number of users from our Google Analytics statistics, so I'm happy to be able to include them in BP Studio.

Hope you will all enjoy this new version! And please don't forget to consider sponsoring, if you haven't done so 😉
