Megacubo 17.7.0: what changed in the September 2026 release
17.7.0 was published on 6 September 2026 and changes nothing about how you use the application: the changes are in the foundation — the environment that hosts the interface —, in window security and in memory during streaming. Anyone updating over the previous version keeps playlists, settings and licence.
What changed
- Electron 44.1.1 — 44.x on Windows and on Linux x64 and ARM64, 43.x on Windows x86. It is the environment that hosts the interface and the player; bumping it brings the project's own fixes and support for newer systems
- Hardened window navigation — control over navigation and over windows opened by link, with web security switched on
- Worker process memory — zero-copy binary emission and length handling in the MPEG-TS stream: less memory work per second of video
- Binary events between processes — the application now supports them; this is what makes the previous change possible
- Countries list fixed in the options, with auto-test on by default
- Minor fixes and assorted improvements

What that changes for the people using it
Less than the version number suggests, and it is worth saying plainly: there is no new feature to learn and no new setting to make. The practical effect is indirect — the application inherits fixes from the environment it runs in, and the video path became cheaper in memory, which is where modest devices usually suffer. If your complaint was stuttering on a TV box, this version does not promise to fix it: it reduces a cost, and low-end device mode is still the setting that changes the outcome.
The security details of this version are on the safety and privacy page.
How to update
- Windows
- Install the new version over the current one using the official installer: playlists and settings are kept — full guide
- Linux
- The portable package is updated by downloading the new release; the install script follows the same release — full guide
- Android and TV boxes
- Download the new APK from the official site; if the installation fails, remove the old version first — full guide
- macOS
- The application has no developer signature on macOS, so the system warns on first launch; Apple documents how to open an application like this
Frequently asked questions
Do I need to do anything after updating to 17.7.0?
No. Nothing in this version changes settings, playlists or licence: the changes are in the foundation (Electron 44.1.1), in window security and in memory use during streaming. Installing over the previous version keeps playlists and settings.
Why is an Electron version bump worth an article?
Because it is the environment that hosts the interface and the player: bumping it brings the project's own security fixes, improves support for newer systems and is the reason the application runs on the same four platforms without separate code for each one.
What is the memory copy that was removed?
In the video path, every piece of data that crosses a process is usually copied. Version 17.7.0 started emitting binary events between processes, which avoids the copy in the MPEG-TS stream — less memory work per second of streaming, which is exactly the kind of cost that shows up on a modest device.
