VS Code 1.123 Adds Cross-Device Agent Session Sync and 1M Token Context

Summary

Microsoft released Visual Studio Code 1.123 on June 3, 2026 with agent-focused upgrades: GitHub-synced chat sessions searchable via /chronicle, side-by-side agent sessions in the Agents window, preview Research Agent (/research), 1M-token context for Claude Opus 4.7 and GPT-5.5, integrated browser screenshot improvements, and a two-hour delay on third-party extension auto-updates. Released alongside Build 2026.

PreScreening Notes

Significant developer-tool release with agent-session sync and 1M-token context — directly relevant to software/AI audience. Primary source (Microsoft VS Code changelog). Complements but does not duplicate Build 2026 pipeline items. Recent (June 3).

Evaluation Report

News Value Assessment

• Prominence: Microsoft primary changelog; Claude Opus 4.7 and GPT-5.5 model support.
• Proximity: Exceptional — Turkish developers overwhelmingly use VS Code; feature-by-feature coverage is directly actionable.

• Direct daily-workflow impact.

Risk & Ethics Assessment

Suggested Angle

Türkçe başlık önerisi: “VS Code 1.123: Agent Oturumları Artık Cihazlar Arası Senkronize”

Changelog formatında kısa ve öz: /chronicle ile oturum arama, Agents penceresinde yan yana oturumlar, 1M token context, Research Agent önizlemesi — her biri bir madde. Türk geliştiriciye “bugün güncelleyin, şunu deneyin” tonuyla yaz. Build 2026 haberleriyle çakışmayan, günlük IDE kullanımına odaklanan ayrı bir brief olarak konumla.
