T3 Code version 0.1.3 is now live! Stable is fully caught up to the nightly :) Pretty small release, here's what's changed since v0.1.2: - Complete redesign of the app to look significantly better - Share threads with a guest in 2 clicks - Opening a thread loads 85% less data, and cold connects send up to 93% less. - Cmd+K search is comically better. - T3 Connect promotes to LAN for using other boxes on same network - File preview overhaul, now supporting office files, mermaid diagrams, sqlite dbs, audio files, pdf annotations, svg attachments, and more - T3's agent instructions are 60% shorter, and the MCP tool schemas are a third smaller. - "steer" is default (queueing sucks) - More reliable PR linking - You can now add custom instructions for title gens - Muse Code now shows in usage tab - All emdashes removed forever - Various accessibility wins for screen reader support - Code highlighting got way faster with @.pierre/highlights - PR timeline, code tab, summary and search got way faster - Streaming text updates are batched, so long runs use less CPU - ~480 other things got merged that I forgot lol ...okay maybe it's a big release.

Why it matters

T3 Code 0.1.3 trims instructions by 60% and tool schemas by a third, makes steering the default over queueing, and cuts thread load data by 85%. It is a concrete update for anyone running coding agents through it.
