Happier 0.2.14 carries the 0.2.13 improvements into refreshed preview and stable builds, while fixing Codex session takeover, self-hosted relay installation, and the Agent directory.
Devin, Antigravity (Agy), FX, and Factory Droid
Experimental sessions for these four Agents are included in the refreshed builds. Devin supports follow-ups and resumable work; Agy uses its ACP server; FX and Droid use their locally installed CLIs and advertise their supported models and modes. Provider installation and sign-in still happen on the computer running the Agent.
Sessions, setup, and updates
The 0.2.13 guided computer setup, clearer update states, session reminders, account-pool controls, and redacted diagnostics remain included. This patch also keeps live Codex App Server ownership intact during takeover and settles the session when its proxy exits.
CLI and website fixes
Self-hosted relay installation now accepts the current payload symlink created by Happier’s installer. Invalid tar links are rejected without leaving a partial extracted payload or an unhandled gzip error. The website now lists all shipped Agent integrations and aligns its Kimi, Cursor, and other capability claims with the shipped manifests.
Compatibility
This patch introduces no new wire format or database migration. The compatibility notes for the 0.2.13 features, including session reminders and local draft migration, still apply.
