new keys default to hashwx, a gpu-resistant proof of work split into 4 sub-challenges (1,000,000 hashes by default). existing keys keep their protocol
hashwx keys need @cap.js/widget 0.1.58 or newer. with the asset server, set WIDGET_VERSION to 0.1.58+ and WASM_VERSION to 0.0.8+
the asset server serves /assets/hashwx.wasm, use it with window.CAP_CUSTOM_HASHWX_URL
rsw is deprecated but stays selectable per key
public share links for a key's stats
key config is cached for 5 s, cutting redis round trips per challenge (based on [#314] by @Devansh-awat)
instrumentation no longer blocks safari without navigator.webdriver, or firefox/safari users on a taller second monitor, and blocking mode fails closed on incomplete probes
the 403 body no longer names the check that blocked the request
static assets send nosniff and cache headers
hardened share link and api key endpoints
