- Invent iso8601us() for faster timestamps - Improve --strace descriptions of sigset_t - Rebuild the Landlock Make bootstrap binary - Introduce MODE=sysv for non-Windows builds - Permit OFD fcntl() locks under pledge(flock) - redbean can now protect your kernel from ddos - Have vfork() fallback to sys_fork() not fork() - Change kmalloc() to not die when out of memory - Improve documentation for some termios functions - Rewrite putenv() and friends to conform to POSIX - Fix linenoise + strace verbosity issue on Windows - Fix regressions in our ability to show backtraces - Change redbean SetHeader() to no-op if value is nil - Improve fcntl() so SQLite locks work in non-WAL mode - Remove some unnecessary work during fork() on Windows - Create redbean-based SSL reverse proxy for IPv4 TurfWar - Fix ape/apeinstall.sh warning when using non-bash shells - Add ProgramTrustedIp(), and IsTrustedIp() APIs to redbean - Support $PWD, $UID, $GID, and $EUID in command interpreter - Introduce experimental JTqFpD APE prefix for non-Windows builds - Invent blackhole daemon for firewalling IP addresses via UNIX named socket - Add ProgramTokenBucket(), AcquireToken(), and CountTokens() APIs to redbean
