Launch Is the Beginning

Getting accepted to the store is just the start. Real success comes from steady updates, responsive support, and staying compliant as policies evolve.

Semantic Versioning

The manifest version must increase with every update. A common scheme is MAJOR.MINOR.PATCH to communicate the size of a change.

{
  "version": "1.4.2"
}

Version Must Always Increase

Stores reject an upload whose version is not higher than the published one. Bump it before every submission, even for tiny fixes.

// 1.4.2 -> 1.4.3 for a hotfix

Auto-Update Mechanics

Once you publish a new version, browsers fetch and install it automatically within hours. Users do not need to do anything.

This makes a broken release dangerous, so test thoroughly.

Staged Rollouts

Both stores let you release to a percentage of users first. Roll out to a small slice, watch for crash reports, then expand.

// Start at 10%, then 50%, then 100% if stable

Detecting the Update in Code

Use the onInstalled event to run migrations or show a what's-new page when the version changes.

chrome.runtime.onInstalled.addListener((d) => {
  if (d.reason === 'update') {
    runMigrations(d.previousVersion)
  }
})

Migrating Stored Data

When your data shape changes between versions, migrate old stored values on update so existing users do not break.

async function runMigrations(prev) {
  if (prev && prev.startsWith('1.')) {
    // reshape old settings here
  }
}

Maintaining a Changelog

Keep a public changelog and update the store listing notes each release. Users trust extensions that communicate clearly about changes.

Responding to Reviews

Reply to store reviews, especially negative ones. A thoughtful reply and a follow-up fix can turn a one-star reviewer into a loyal user.

Staying Policy Compliant

Store policies change. Periodically re-read the developer policies, tighten permissions, and update your privacy disclosures to avoid sudden removal.

Handling Deprecations

Browser APIs get deprecated over time. Watch developer announcements and migrate before removed APIs break your extension for everyone.

Quick Check

Test your maintenance knowledge.

Recap

You learned post-launch maintenance:

Bump the manifest version every release
Use staged rollouts and test before publishing
Run migrations in onInstalled
Keep a changelog and reply to reviews
Stay compliant and ahead of deprecations

Consistent maintenance keeps your extension healthy long after launch.
