Overview

Learn why keeping your mobile SDKs—like OneSignal—updated is essential for app health, and how to build updates into your workflow.
If you’re just getting started with OneSignal, see the Mobile SDK setup guide.

OneSignal SDK releases

All OneSignal SDKs are open source. Use the links below to access the latest versions and release notes:
Want early access to new features? OneSignal also publishes beta releases for testing and feedback.

Why updating mobile SDKs matters

Your app relies on SDKs for critical features like messaging, analytics, and engagement. Regular updates help you:
  • Unlock new features – Improve UX and boost engagement.
  • Enhance performance – Stay fast and stable.
  • Stay secure – Fix vulnerabilities before they impact users.
  • Maintain compatibility – Avoid issues with OS or SDK version changes.
Outdated SDKs increase technical debt, introduce bugs, and delay your access to new capabilities.

Why frequent updates are easier

Smaller, more frequent updates reduce complexity and risk. Benefits include:
  • Fewer breaking changes to fix.
  • Easier debugging and regression testing.
  • Faster adoption of vendor support and best practices.
Example: OneSignal iOS SDK v5.2.0 introduced Live Activities PushToStart—an enhancement only available by updating.

Why teams delay SDK updates (and how to fix that)

“We don’t have time”

  • Reality: Most SDK updates are quick.
  • Fix: Use versioning to scope the effort:
    • PATCH (e.g. 5.2.0 → 5.2.1): Small fixes. Safe to auto-upgrade.
    • MINOR (e.g. 5.2.2 → 5.3.0): New features, backward compatible.
    • MAJOR (e.g. 5.2.2 → 6.0.0): Breaking changes. Needs review and planning.

“If it works, don’t touch it”

  • Reality: “Works” doesn’t mean “optimized” or “future-proof.”
  • Fix: Review changelogs to understand what’s improved and what risks you’re carrying.

Build SDK updates into your workflow

1. Set a regular cadence

  • Review SDK versions monthly or quarterly.
  • Batch PATCH/MINOR updates in normal sprints.
  • Schedule MAJOR updates with dedicated planning.

2. Assign clear roles

  • SDK Owner – Tracks new releases and initiates upgrades.
  • Developers – Implement and test updates.
  • Marketing/Product – Identify and use new capabilities.

3. Automate where possible

  • Use scripts to monitor SDK versions and notify your team.
  • Add SDK version checks to your CI/CD pipeline.
  • Set up alerts for performance changes post-update.
After an SDK update, always test notification delivery and user engagement to catch regressions early.

Communicate SDK updates internally

  • Share changelogs with cross-functional teams.
  • Include updates in sprint demos or standups.
  • Keep internal docs current—prevent confusion from outdated guidance.

Encourage users to update the app

SDK updates only reach users if they update your app. Use in-app messaging or push notifications to:
  • Inform users about new updates.
  • Promote benefits (e.g. speed, stability, new features).
  • Encourage downloads from the app store.

TL;DR: Make SDK updates a habit

  • Treat SDK updates like routine maintenance—don’t wait until something breaks.
  • Avoid major version leaps by updating frequently.
  • Use versioning and automation to stay ahead.
  • Make it a team responsibility, not a one-off task.
  • Start by auditing your current SDK versions and update any that are out of date.
