 - [2026-07-28] Web App and CLI: duration and byte abbreviations now carry into the next unit instead of printing `1m60s` or `1024KB` — both helpers rounded the value they displayed but chose the unit (or the minute/second split) from the raw input. ([details](2026-07-28-duration-and-byte-formatting.md))
 
+- [2026-07-27] Input images: mid-run steering carries them (an uncaptioned image is a complete steering message), a goal objective accepts them as scratchpad paths on every model since it is re-injected as text each round, and the composer's mid-run action button can no longer sit disabled with Stop displaced.

 - [2026-07-27] Windows: the `win32-x64` package bundles MinGit under `git/`, so `exec_command` has a real bash even on a machine with no Git for Windows — the shell stops depending on what happens to be installed. A user's own Git for Windows still wins (its MSYS userland is the fuller one); the bundle is the floor, and PowerShell is now reached only by npm installs. GPLv2 obligations are recorded in a new root `THIRD-PARTY-NOTICES.md`. ([details](2026-07-27-windows-bundled-shell.md))
