The headline feature is FlakeHub Cache edge routing: requests are now automatically routed to the nearest cache node, making substitution substantially faster for users outside the US (including Australia, Asia, and Africa). Determinate Nixd handles the configuration automatically with no user changes required. The release also includes three crash fixes: a worker thread leak in libgit2's ll_find_delta, suppression of SIGQUIT from Sentry reporting, and a graceful error instead of abort when NIX_GET_COMPLETIONS is out of range. ## Full article daily.dev links to this article rather than hosting it.
