The release notes also mention some functionality currently under development.

Lua timer module

The new timer functionality just barely missed this release. It will now land in the next release.

Live update

The tasks of the live update feature are now into its final stages
and should be available soon for release.

Native extensions

We are currently working on optimizing the build times for Win32/Win64.
Early tests are really promising but there are a series of small tasks that needs to be done
in order for this to work well.

Today was Apple’s annual developer conference WWDC with the usual swath of new products and betas announced.  Among the announcements was one of direct importance to game developers everywhere.

From the document What’s New in iOS 12:

Deprecation of OpenGL ES

Apps built using OpenGL ES will continue to run in iOS 12, but Open GL ES is deprecated in iOS 12. Games and graphics-intensive apps that previously used OpenGL ES should now adopt Metal.

Metal is designed from the ground up to provide the best access to the modern GPUs on iOS, macOS, and tvOS devices. Metal avoids the overhead inherent in legacy technologies and exposes the latest graphics processing functionality. Unified support for graphics and compute in Metal lets your apps efficiently utilize the latest rendering techniques. For information about developing apps and games using Metal, see the developer documentation for Metal, Metal Performance Shaders, and MetalKit.

They will also be deprecating OpenGL support in the next Mac OS version “Mojave”.  Deprecating doesn’t mean that OpenGL will stop working on those platforms, but it may in future OS revisions.  What it does mean however is that OpenGL support will no longer be updated, no new features, no new drivers, etc.  So basically if you want high performance 3D graphics on iOS and MacOS devices, you now have to use their native API Metal.  

If you want to develop cross platform for Apple platforms going forward you either need to use a game engine that does the work for you, or write a Metal renderer for iOS and MacOS targets.  There might be some hope however in the form of MoltenVK which enables Vulkan code to run on Metal.

It turns out the rumour over the weekend was true, Microsoft did in fact spend $7.5 billion to acquire GitHub.  GitHub is the largest open source code repository implementing the open git standard.  Being an open standard means moving your code off of GitHub is easy to do, so Microsoft needs to keep customers through good service going forward.  Both GitHub and Microsoft have released statements about the acquisition:

From GitHub:

We both believe that software development needs to become easier, more accessible, more intelligent, and more open, so more people can become developers and existing developers can spend more time focusing on the unique problems they’re trying to solve.

We both see the growing need for developers and the growing importance of software in all facets of our lives.

And, most importantly, we both believe we can do greater things together than alone. Collaboration, after all, is at the heart of everything we do.

From Microsoft:

First, we will empower developers at every stage of the development lifecycle – from ideation to collaboration to deployment to the cloud. Going forward, GitHub will remain an open platform, which any developer can plug into and extend. Developers will continue to be able to use the programming languages, tools and operating systems of their choice for their projects – and will still be able to deploy their code on any cloud and any device.

Second, we will accelerate enterprise developers’ use of GitHub, with our direct sales and partner channels and access to Microsoft’s global cloud infrastructure and services.

Finally, we will bring Microsoft’s developer tools and services to new audiences.

Most importantly, we recognize the responsibility we take on with this agreement. We are committed to being stewards of the GitHub community, which will retain its developer-first ethos, operate independently and remain an open platform. We will always listen to developer feedback and invest in both fundamentals and new capabilities.


It will be interesting to see how this turns out.  I see little reason to be afraid of this acquisition as Microsoft doesn’t have a competing product in this sector, having shut down CodePlex last year.  Now as a stand alone unit under Microsoft, Github should hopefully be extremely well funded going forward.

Godot 3.0.3 RC3 was just released.  This release focused heavily on getting Mono exporting working properly:

Quite a lot of work went into making the Mono exports work for Windows targets. It turned out to be quite a hairy problem. But now Mono exports to Windows, Linux, and MacOS should work with a single click. It is no longer necessary to ship the Mono runtime DLL manually.

In this release JavaScript export templates were also restored after being broken in RC2.

There are however some changes and known issues you should be aware of in this release.  Details from the release announcement blog:

Known incompatibilities with Godot 3.0

  • If you use the Bullet physics engine and relied on the fact that the calculated effective gravity on KinematicBodies was always '0' then you will need to fix your code as this is now correctly calculated. See #15554 for details.
  • Setting the v member of a color did not properly set the s member. This is now corrected. See #16916 for details.
  • RichTextLabels did not properly determine the baseline of all fonts. If you relied on the look of the previous implementation please let us know. See #15711 for details.
  • SpinBoxes didn't calculate their width properly. This is now fixed but could subtly change your GUI layout. See #16432 for details.
  • OGG streams now correctly signal the end of playback. If you were relying on this not happening please let us know. See #15910 for details.

Known bugs in Godot 3.0.3

  • Vector3.snapped() does not work and just returns the original Vector3. Fixing this would have meant breaking ABI between Godot 3.0 and 3.0.2 so this function will remain non-functional.
  • move_and_slide() doesn't quite work correctly. An easy workaround is to increase the safe margin to 0.05 (or higher if required). It is not yet clear how to implement the proper fix without impacting users who already implemented this workaround in their projects. See issue #16459 for an explanation.
  • Some users report crashes on Windows 10 after a recent Windows update. We currently don't know what is causing this.

The 3.0.3RC3 release is available for download here.
