🤖 I have created a release beep boop

0.4.0 (2026-09-06)

Features

• Raven gets a window, and the audit that came with it (958f38e)

Bug Fixes

• a Direct3D install that fails part way can still be undone (315d224)
• a program given by a relative path is found where the user meant it (bebcaf7)
• a session anchor is recognised by what it runs, not by its name (37c15f2)
• an absolute program path does not need a working directory to exist (1487679)
• an interrupted deploy no longer leaves a base nothing can finish (1b26eb4)
• detach touches only the drives Raven itself attached (cc57745)
• gui: Environments stays lit in the sidebar while a detail shows (f599ff6)
• gui: Start works, because the window can be its own session anchor (644765d)
• gui: the button that ends the user's programs says so (d88aeef)
• only Raven's own working directories are hidden from base list (68e0a0b)
• release-please could not open a pull request against a virtual manifest (15d7503)
• the projection example belongs to a crate again (afb5b27)
• the window can no longer be asked to do what only the launcher can (053319e)
• the window could no longer stop an environment anything was using (3ec536b)
• the window reports the check that matters most, and says why things failed (a7617cc)
• the window's Start really starts, and three failures say more (c2b728c)
• two silent failures in creating and reading an environment (4981d81)

Performance Improvements

• a warm launch no longer scans every process to find one of them (838bf92)
• gui: the bases screen counts environments without reading them (2b3b33d)
