About Buttondown
A near-daily fix stream, with flexible monthly RSS scheduling the only real addition.
Buttondown publishes a dated entry almost every day, and the overwhelming majority are single bug fixes, several credited by name to the subscriber who reported them. The current window is nine-tenths repair work — stretched newsletter icons in the archive, a portal 403 for subscribers with many accounts, rejected WebP uploads, cursor placement between stacked tables. Two genuine features sit at the window's edges: filtered blocks on July 31 and flexible monthly RSS scheduling on August 1. Every entry is titled with its date alone, so the titles carry no signal until rewritten.
