I looked for a devlog and itch.io returned a 404 for /the-masterplan/devlog on 2026-10-27. There is no patch-note essay. The timeline below is only what the game page, the itch.io update event, and one comment can support. If a cell says “not stated,” Garcia did not state it.

Why this page stays short

A longer update log would be fiction. I am not going to number a “Patch 1.1” to make the table look finished. When the itch.io “Updated” line changes, this page should change with it, and the date at the top should move. Until then, the useful news is: a later upload event lists both zips, and one slow walk was sped up.

Download the current zips from the steps on the download page. Do not keep a third-party reupload. The file sizes on 2026-10-27 were still 170 MB and 172 MB.
