What's New 2026.4.1

Last updated on September 2, 2026

Release date: September 2nd, 2026

Component versions​

The AccelByte Development Toolkit (ADT) 2026.4.1 patch release contains the following component versions:

  • ADT Hub v1.12.1
  • ADT Web v1.37.1
  • ADT SDK Unreal/Unity v2.34.1

Release Highlights​

Playtest Session Log​

New

Playtest channels in ADT Hub now have a Sessions tab that lists every player session for a playtest build — crashed or not — so studio coordinators aren't limited to investigating only the sessions that happened to crash.

What's New

  • One row per session, showing player, role, platform, duration, and result (Completed / Crashed).

  • Crashed sessions are visually distinguished from completed ones.

  • Download log for any session, crashed or completed — not just crash-triggered captures. If a log never arrived (e.g., connection dropped before upload), the download is shown as unavailable with a short explanation instead of producing a broken file. Log capture/download is Windows-only in this release; macOS sessions still appear in the list but show download as unavailable.

  • Search by player name, role, or session ID, plus a filter for crashed-only sessions.

  • Sessions list is scoped to the playtest's active window and only includes builds played through ADT Hub, and is sorted with the most recent session first.

  • Access follows the same rule as the other playtest tabs (Playtesters, Feedback, Errors) — no extra role restriction, and the log download link enforces the same channel-access check server-side.

What This Means for You

Studio coordinators can now dig into playtest sessions that never crashed — stutters, unexpected behavior, slow loading — instead of only having visibility into sessions that triggered a crash report.

How to Try It

  • Open a playtest channel in ADT Hub.

  • Go to the new Sessions tab.

  • Search or filter to find a specific session.

  • Select Download log on any row to pull that session's log file.

Crash Timeline (Breadcrumbs) — Graph Pins Reach Beta​

Beta

Phase 2 of the Breadcrumb performance-graph pin overlay (introduced in 2026.4) graduates from Alpha to Beta, with a round of accuracy and usability fixes based on early feedback.

What's New

  • Pins now render directly on their metric line at the correct value/height, instead of a fixed row above the chart.

  • The crash entry itself now appears in pin and cluster popovers, matching what's shown in the crash's Breadcrumb tab.

  • Timestamps for a given event are now consistent across the pin popover, the crash header, and the session log view.

  • Each entry in a cluster popover now shows a color-coded dot matching its category, consistent with the rest of the UI.

  • Pin popups now include a close (✕) button instead of requiring a click outside to dismiss.

  • The Breadcrumb tab now loads more entries via infinite scroll instead of requiring repeated "Load more" clicks.

What This Means for You

The performance-graph pin overlay is more accurate and easier to use, making it more reliable to correlate a crash or hitch with the surrounding log activity directly on the graph.

How to Try It

  • Open any session or crash detail page and go to the Basic Profiling tab.

  • Click a pin or cluster to see the entries at that point in time.

Bug Fixes and Improvements​

  • Blackbox Helper crash: Fixed a recurring crash in the Blackbox helper process (exit code 3221225781) that flooded client logs with Blackbox helper is stopped with exit code ... errors.
