Notes

This is our new annual Long Term Support (LTS) release of Construct, based off the stable release r449, with a couple of additional fixes included in this update. This LTS release will be supported with essential bug fixes and maintenance up until the end of 2026. Support for the previous r397 LTS release is only scheduled to last until the end of 2025, so only a couple months of support is remaining. Beyond that the last r397 LTS release will remain available, but not receive any further updates, so further use will be at your own risk. Therefore we would encourage any r397 LTS users to start planning to update to r449 LTS. Learn more about release channels and the support schedule in the Construct release channels manual entry.

The r450 release is a major compatibility milestone, retiring support for the following features:

• Legacy (SDK v1) third-party plugins and behaviors (r450+ only supports SDK v2)

• The NW.js exporter (r450+ only supports the Windows WebView2, macOS WKWebView, and Linux CEF exporters)

• Support for exporting to Windows 32-bit (x86) and Linux ARM 32-bit

• The legacy "flat" export file structure

• The legacy "file" scheme for iOS and Android

The r449 LTS releases are the last releases that will still support all of the above. This extends support for legacy projects that still need these features, while allowing the latest Construct releases to move ahead focusing on more reliable features that are easier to support. We would encourage changing projects using these legacy features to stop using them and continue using the latest Construct release where possible, but the r449 LTS releases will provide an alternative option where that is not feasible.

  • Thank you for doing this, much appreciated.

  • Last time I did this, the next time a stable update came out, it just upgraded to that instead.

    In the settings I can set it to beta or stable. Where's LTS?

  • I really appreciate this, it's a godsend for keeping my webkit dependent projects workable and one of the reasons I'm sticking with C3.

  • I love the LTS branch and will definitely use it for long term projects ^^ Thanks a lot!

  • It would be great to have a dropdown menu on the main screen of construct 3 that allows us to select which version of the editor we want to use, since many addons that we use in our projects are not converted to the SDK v2 format yet.

  • How do I install multiple c3 versions as applications? Since sdk v1 was retired, I've had both the beta and stable versions installed as applications. Today I uninstalled the stable one so I could install the LTS, but instead of giving me the option to install as an app, it prompts me to open the LTS version in the beta application, meaning there's no quick way for me to launch LTS from my desktop.

  • Awsome

  • Thanks!
