When Delta Executor suddenly stops working, the cause is almost never your phone. It is almost always the version you are running. This page keeps a running version history of every recent Delta build, explains the one rule that decides whether Delta works, and walks you through a quick check you can run right now.
Delta Executor Version History
These are the recent Delta builds, newest first. Version numbers and release months come straight from our Delta old versions archive, so what you see here matches what is published there.
| Version | Released | What changed | Status |
|---|---|---|---|
| v2.743 (build 2.743.1136) | 20 October 2026 | Compatibility fix for the newest Roblox client change; stronger anti-ban layer | Current |
| v2.742 | October 2026 | Compatibility patch for the latest Roblox client; key-flow stability fixes | Superseded |
| v2.741 (build 2.741.1062) | September 2026 | Previous stable release | Superseded |
| v2.738 | September 2026 | Script hub refresh; faster injection | Superseded |
| v2.727 | August 2026 | Roblox client compatibility update; UI polish | Superseded |
| v2.689 | Mid 2026 | Stability release; kinder to older Android 8.0-9 devices | Legacy |
Old versions break the moment Roblox updates its client, so the current build is the right choice in almost every case. The old versions page explains the few situations where an older build still makes sense.
The Build-Match Rule: Why Delta Breaks After Roblox Updates
Delta works when its build matches the Roblox build it was released for. Roblox updates its client regularly, and each update changes the Roblox build number. When that happens, the current Delta build stops working until the Delta team ships a new build that matches. That is why Delta can run perfectly on Monday and refuse to work on Tuesday, with nothing changing on your phone.
Roblox and Delta use different version numbering, so do not expect the numbers to look alike. What matters is timing: the Delta build you installed must be the one released to match the Roblox client you have now. Right now that means Delta v2.743 (build 2.743.1136) against Roblox 2.744.1081.
Is Delta Working Right Now?
Run these checks in order. The first “no” is your answer.
- Are you on the latest Delta? Open Delta and check the version. If it is anything older than v2.743, update first. You can download the latest Delta build from our download page.
- Did Roblox just update? If Roblox pushed an update in the last day or two and Delta has not released a matching build yet, you are in the gap. This is normal. It fixes itself when the matching Delta build releases.
- Is Roblox itself up to date? Update Roblox from the Play Store or App Store as well. A new Delta build paired with an old Roblox install can still fail.
- Is your key valid? Keys last 24 hours. If Delta asks for a key again, generate a fresh one using our Delta key guide.
- Does it work without scripts? Launch a game with no script running. If Delta works now, a heavy or outdated script is the culprit, not Delta.
If you answered yes to all five, Delta is working and the issue is something local. Reinstall Delta cleanly, clear its cache, or look up your exact error in our Delta not working fixes.
What To Do If Delta Is Down
- Confirm a new Roblox update just landed by checking this page and the version history.
- If it did, wait. A matching Delta build usually follows quickly. Reinstalling the same build over and over changes nothing.
- When the new build is out, update both apps: Roblox from your app store and Delta from the download page.
- Do not edit version numbers in any file, and do not download a so-called “fixed” build from a random site. Those are the two fastest ways to end up with malware.
One more thing: “Delta X” is just the community nickname for Delta Executor. Same tool, same app, and every version rule on this page applies to it exactly the same way.
