What's new in Kiro CLI, May 2026
Kiro CLI adds chat.disableWrap, /model set-current-as-default and MCP env var fixes
Kiro CLI's May 2026 changes center on terminal and chat usability, plus fixes for MCP configuration and Windows. Seven releases shipped, from v2.2.0 to v2.5.0.
v2.2.1 added a chat.disableWrap setting for clean copy-paste, a /model set-current-as-default command, autocomplete for /agent swap, and tighter approval on out-of-workspace reads. It also fixed issues with tmux sessions, terminal resizes, Windows line endings, and API key authentication outside us-east-1. Later patches fixed ${VARNAME} syntax for environment variable expansion in MCP server configuration (v2.4.1) and a Windows crash in terminal input handling (v2.4.2). The notes for v2.2.0, v2.3.0, v2.4.0 and v2.5.0 give no details beyond the version number.
