 ## Debugger Changes
+- **The debugger now has preliminary support for native Linux x64 debugging.**
+  It's still *very early*, and there is surely a lot to fix, so please expect a
+  less stable experience than on Windows! But it is now finally in a state that
+  we feel it'd be helpful for people to try it, so that we can begin
+  battle-testing the debugger on Linux also. Here are a list of known issues
+  and caveats:
+  - We are not releasing any binaries for Linux yet, so we've provided
+    instructions for locally building the debugger in the codebase's
+    `README.md`.
+  - We do not support debugging of code which uses `fork` and `vfork` yet.
+  - When computing locations of thread-local storage, we currently assume that
+    the debuggee uses the same libc version as the debugger.
+  - We do not currently correctly unwind when the `.eh_frame_hdr` section is
+    missing. This is normally there by default, but this may explain some
+    broken callstacks you encounter. It can be enabled by passing the
+    `--eh-frame-hdr` flag to the linker, if it's not enabled by default.
+  - Bitfield type info is not yet supported correctly.
+  - In some cases, our type deduplication (when converting from DWARF to RDI)
+    is not working correctly. (#959)
+  - Sometimes, a keyboard combination will incorrectly send text events. (#954)
+- The debugger now has preliminary support for loading Minidump (`.dmp`) files.
+  They can be opened with the `Open Crash Dump` command.
+- Added a breakpoint setting which causes breakpoints to only break if they're
+  hit by the currently selected thread, if there is a selected thread. If there
+  isn't a selected thread yet, all threads will still cause a break.
+- Added a setting, `Lock New Breakpoints To Selected Thread`, which turns on
+  the aforementioned breakpoint setting by default on all newly placed
+  breakpoints.
 - Reintroduced `Browse` buttons for cells that edit file paths, which spawn a
   file picker, to more conveniently choose paths.
 - The debugger now tags watch expressions with the selected project, which

   visualized) in source and disassembly views is now clickable, as a fastpath
   for `Run To Line`.
 - The position of the destination of a `Run To Line` command is now visualized.
+- The debugger now better visualizes the status of loading debug info in the
+  `Modules` tab.
+- The debugger's IPC system is now built on sockets rather than shared memory
+  ring buffers. This is mostly an implementation detail, but it has introduced
+  some noteworthy changes. First, communication with instances of the graphical
+  debugger is now done through network ports, rather than through process IDs.
+  By default, this port is `7423`, but it can be changed per-instance by
+  passing the `--ipc_port` command line option, e.g. `raddbg --ipc_port=1234`.
+  Furthermore, this also means that IPC commands can be sent over the network.
+  This is unlikely to be especially helpful right now. But to do this, you can
+  pass an IP address and port when sending a command, e.g.:
+  `raddbg --ipc --ipc_addr=123.45.67.89:1234`.
+- The debugger now allows using a single font for the entire interface, if you
+  want the UI elements and code to be drawn in a more uniform style. This is
+  available through the `Use Alternative Font For UI` setting.
+- Fixed a performance issue when computing very large call stacks with many
+  very small frames (fixes missing call stacks in some stack overflow cases).
+  (#963)
+- Fixed `raddbg.com` adding the debugger as a command line target to itself
+  incorrectly. (#946)
+- Fixed many other minor bugs and instabilities.
