+MontaukOS 0.2.0 (October 14, 2026)
+    (278b20825815ec04a22fd1c2fcfedbd38e116e6d)
+
+New
+====
+    * Kernel capability model - processes run with a capability set, and protected paths and privileged syscalls are gated on it
+    * Permission consent prompts - apps ask before first use of a protected capability, and answers are remembered
+    * New Capabilities app for reviewing and managing app permissions
+    * Unified system status codes; the shell and Files now print a readable message on failure
+    * Text is now UTF-8 throughout, with Unicode key events and dead keys
+    * Keyboard layout support, with English, Norwegian, Czech, Swedish, and Danish layouts
+    * NumLock support
+    * Battery percentage reporting via ACPI, with a battery indicator in the desktop panel
+    * Display brightness control, including on hybrid graphics laptops, with a slider in the desktop panel
+    * Discrete GPUs are powered down automatically on hybrid graphics laptops
+    * ext2 block cache with readahead, speeding up disk-heavy work such as on-OS compilation
+    * Userspace system logging: klog is now syslog, logs identify the user and program, and system services log through montauk::service_log
+    * The system log is written to disk (0:/state/logs) during shutdown
+    * Desktop sessions now own the processes started in them, and those processes are ended on logout
+    * Rust userspace support (no_std)
+    * Futex syscalls (SYS_FUTEX_WAIT/SYS_FUTEX_WAKE) as groundwork for Rust std and pthreads
+    * Process termination codes; abort() now ends the whole process from any thread
+    * isatty() now reports whether a terminal is actually attached
+    * Settings panel and a Pure Black theme in Terminal (the default for Console sessions)
+    * Syntax highlighting for C++, HTML, CSS, and JavaScript in edit and Text Editor
+    * Expanded SVG renderer
+    * New vol command for listing mounted volumes
+    * Revamped desktop application categories
+    * Fonts, icons, and manual pages moved to 0:/os; persistent state now lives in 0:/state
+    * RTL-SDR driver moved from the kernel to userspace
+
+Fixed
+=====
+    * Opening a directory as a file is now rejected on ext2 and FAT32, fixing on-OS gcc on installed systems
+    * Fixed several syscall result and status code comparisons
+    * Fixed a TLS layout bug for binaries whose TLS segment has an alignment below 16
+    * A fault in one thread now ends the whole process instead of leaving its sibling threads running
+    * Fixed an ACPI hardware ID endianness bug
+    * Fixed a race in Wi-Fi event processing and other Wi-Fi bugs
+    * DHCP no longer runs when no network device has an active link
+    * Reduced idle CPU wakeups and deferred-work polling
+    * Redirected consoles are now inherited by processes spawned with capabilities
+    * Fixed numpad navigation
+    * Fixed a timezone formatting bug
+    * Fixed the login wallpaper startup delay
+    * Fixed text overlap in file dialogs
+    * Persisted kernel logs are no longer double-spaced
+    * Files lists now scroll with the arrow keys, and volume labels are consistent
+    * mbrtowc added to libc
+
+Included in ISO
+================
+
+    Two x86_64 images are published for this release.
+    montauk-0.2.0-sdk-x86_64.iso additionally carries the
+    Montauk SDK (gcc, binutils, etc.)
+
+    * MontaukOS SMP kernel
+    * Userspace bootstrap (0:/os/init.elf) and other essential system utilities
+    * MontaukOS desktop environment and graphical apps
+    * NetSurf web browser (0:/apps/netsurf)
+    * Manual pages (0:/os/man), readable via man command
+    * Service and system configuration (0:/config: init.toml, capabilities.toml, ssh.toml, ntp.toml)
+    * System CA certificates (0:/os/certs/ca-certificates.crt)
+    * Intel Bluetooth controller and Wi-Fi (iwlwifi) firmware (0:/os/firmware/intel)

+    * Lua 5.4 interpreter (lua) with headers and static library (0:/sdk/lua)
+    * Montauk SDK - native GCC/G++ and binutils (0:/sdk) - SDK image only
+    * Flat Remix icon pack
+    * JetBrains Mono, Noto Serif, Roboto, and C059 Roman (open Century Schoolbook) TrueType fonts
+    * DOOM engine with SDL_mixer audio support (game data not included)
