Version Info Guide: Understanding Update Details

Version Info: What’s New in the Latest Release

Keeping track of what changed in each release helps users, developers, and support teams move faster and avoid surprises. This article summarizes the latest release’s Version Info, highlights the most important changes, explains how to read the version metadata, and lists actions you should take after updating.

Release at a glance

• Version: 4.2.0
• Release date: May 19, 2026
• Type: Minor feature + bugfix release
• Compatibility: Backward compatible with 4.x; no database migrations required

Key highlights

1. New: Smart Sync for Offline Edits

   • Devices can now queue edits while offline and merge them automatically when reconnecting.
   • Conflict resolution uses edit timestamps and user IDs; manual merge UI appears only for ambiguous conflicts.

2. Improved: Search Relevance

   • Search ranking updated to weight recent documents higher and to better handle synonyms.
   • Performance: average query latency reduced by ~20% on mid-size datasets.

3. Added: API Rate-Limiting Headers

   • Clients now receive standardized headers: X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset.
   • Helps integrations implement graceful backoff and retry strategies.

4. Fixed: File Upload Failures on Large Files

   • Resolved intermittent upload timeouts for files >200 MB by improving chunk retry logic and server-side buffering.

5. Security: Hardened Session Tokens

   • Session tokens now include an extra integrity check and shorter default TTL; long-lived tokens require explicit opt-in.

6. UI: Accessibility Improvements

   • Keyboard navigation fixes across the settings pages and improved aria-labels for screen readers.

Version metadata — how to read it

• Format used: MAJOR.MINOR.PATCH (e.g., 4.2.0)

  • MAJOR: Breaking changes or incompatible API updates.
  • MINOR: New features, backward-compatible enhancements.
  • PATCH: Bug fixes, performance and security improvements.

• Build identifier: 20260519-4.2.0-b12 — includes build date, version, and build number.

• Changelog GUID: a unique identifier linking this release to extended release notes and audit logs.

Impact by audience

• End users: Expect smoother searching, more reliable uploads, and fewer sync surprises. No action required beyond updating.
• Developers / Integrators: Update client libraries to read the new rate-limit headers; test merge behavior for offline edits.
• Admins: Review token policies for required TTL changes and evaluate whether to allow long-lived tokens for specific service accounts.

Post-update checklist

1. Backup current configuration and data (standard precaution).
2. Update client applications and SDKs to the latest compatible version.
3. Monitor logs for any increased error rates in the first 48 hours.
4. Confirm automated backups and retention policies still behave as expected.
5. Communicate key UX changes to support teams (search improvements, conflict merge UI).

Troubleshooting common issues

• If uploads still fail for large files: enable verbose client-side logging, check network MTU settings, and verify server buffer limits.
• If offline edits conflict frequently: ensure device clocks are synchronized (NTP) and review edge-case workflows that create simultaneous edits.
• If integrations ignore rate-limit headers: implement exponential backoff and make retries conditional on the X-RateLimit-Remaining value.

Where to find detailed info
