+<h4>New</h4>
+<ul>
+<li>Kernel capability model - processes run with a capability set, and protected paths and privileged syscalls are gated on it</li>
+<li>Permission consent prompts - apps ask before first use of a protected capability, and answers are remembered</li>
+<li>New Capabilities app for reviewing and managing app permissions</li>
+<li>Unified system status codes; the shell and Files now print a readable message on failure</li>
+<li>Text is now UTF-8 throughout, with Unicode key events and dead keys</li>
+<li>Keyboard layout support, with English, Norwegian, Czech, Swedish, and Danish layouts</li>
+<li>NumLock support</li>
+<li>Battery percentage reporting via ACPI, with a battery indicator in the desktop panel</li>
+<li>Display brightness control, including on hybrid graphics laptops, with a slider in the desktop panel</li>
+<li>Discrete GPUs are powered down automatically on hybrid graphics laptops</li>
+<li>ext2 block cache with readahead, speeding up disk-heavy work such as on-OS compilation</li>
+<li>Userspace system logging: <code>klog</code> is now <code>syslog</code>, logs identify the user and program, and system services log through <code>montauk::service_log</code></li>
+<li>The system log is written to disk (<code>0:/state/logs</code>) during shutdown</li>
+<li>Desktop sessions now own the processes started in them, and those processes are ended on logout</li>
+<li>Rust userspace support (<code>no_std</code>)</li>
+<li>Futex syscalls (<code>SYS_FUTEX_WAIT</code>/<code>SYS_FUTEX_WAKE</code>) as groundwork for Rust std and pthreads</li>
+<li>Process termination codes; <code>abort()</code> now ends the whole process from any thread</li>
+<li><code>isatty()</code> now reports whether a terminal is actually attached</li>
+<li>Settings panel and a Pure Black theme in Terminal (the default for Console sessions)</li>
+<li>Syntax highlighting for C++, HTML, CSS, and JavaScript in <code>edit</code> and Text Editor</li>
+<li>Expanded SVG renderer</li>
+<li>New <code>vol</code> command for listing mounted volumes</li>
+<li>Revamped desktop application categories</li>
+<li>Fonts, icons, and manual pages moved to <code>0:/os</code>; persistent state now lives in <code>0:/state</code></li>
+<li>RTL-SDR driver moved from the kernel to userspace</li>
+</ul>
+<h4>Fixed</h4>
+<ul>
+<li>Opening a directory as a file is now rejected on ext2 and FAT32, fixing on-OS gcc on installed systems</li>
+<li>Fixed several syscall result and status code comparisons</li>
+<li>Fixed a TLS layout bug for binaries whose TLS segment has an alignment below 16</li>
+<li>A fault in one thread now ends the whole process instead of leaving its sibling threads running</li>
+<li>Fixed an ACPI hardware ID endianness bug</li>
+<li>Fixed a race in Wi-Fi event processing and other Wi-Fi bugs</li>
+<li>DHCP no longer runs when no network device has an active link</li>
+<li>Reduced idle CPU wakeups and deferred-work polling</li>
+<li>Redirected consoles are now inherited by processes spawned with capabilities</li>
+<li>Fixed numpad navigation</li>
+<li>Fixed a timezone formatting bug</li>
+<li>Fixed the login wallpaper startup delay</li>
+<li>Fixed text overlap in file dialogs</li>
+<li>Persisted kernel logs are no longer double-spaced</li>
+<li>Files lists now scroll with the arrow keys, and volume labels are consistent</li>
+<li><code>mbrtowc</code> added to libc</li>
+</ul>
+<h4>Known issues</h4>
+<ul>
+    <li>Intel GPU may struggle to wake up from S3 sleep, causing a black screen requiring a reset. S3 sleep is highly experimental and users are discouraged from relying on it.</li>
+    <li>Due to licensing restrictions, the proprietary DOOM WAD cannot be shipped; the DOOM engine warns at launch when no compatible WAD file is present, and game content is unavailable until the user supplies one.</li>
+</ul>
