-# v0.9.28-alpha
-
-## Linker Changes
-- Implemented `/OPT:ICF` identical COMDAT folding.
-- Added DEF, and SECTION configuration support.
-- Improved COMDAT handling for weak symbols, ICF, and zero-sized COMDAT
-  anchors, and stopped emitting empty marker sections that could produce invalid
-  PE images.
-- Fixed import/export edge cases, including import data-directory bounds and
-  archive member handling for `__imp_*` symbols.
-- Accepted duplicate identical weak search aliases without reporting multiply
-  defined symbols.
-- Add support for UTF-16 encoded response files.
-- Fixed DBI section-contribution image-section range mapping.
-- Improved debug logging for `/OPT:REF` liveness stats and unresolved symbols
-  referenced by `.llvm_addrsig`.
-
-# v0.9.27-alpha
-
-## Debugger Changes
-
-- Fixed an issue which would rarely cause steps to take a long time.
-- Drastically improved memory usage of PDB -> RDI conversion for some
-  workloads, notably PDBs with many small compilation units.
-- Added the ability to disambiguate symbol names by module name, debug info
-  name, or compilation unit name in expressions. This can be done using the
-  usual syntax, e.g. `my_module.dll!foo`, or `my_unit.obj!foo`. `:` can also be
-  used instead of `!`.
-- Added the ability to redirect debug string output to any label on a
-  per-target basis. Those labels can then be evaluated in any watch window or
-  text visualizer. By default, all targets write to `output`, which is
-  automatically visualized by an `Output` tab. But if you want different
-  targets to route their debug output to different buffers, you can name the
-  buffers differently, and then view those in separate text views.
-- Added a `Run To Name` command.
-- Added an `Auto Load Last Project` setting, which will automatically load the
-  most recently loaded project on startup (the old behavior pre-0.9.26). This
-  setting is off by default.
-- Added right-click menus for watch expressions, to easily find them in a
-  memory view, or to break when their value changes.
-- Added preliminary support for symbol servers. First, the debugger can attempt
-  to download debug info for any module via the `Download Module Debug Info`
-  command (also accessible by right-clicking a module). Second, the debugger
-  can be configured to automatically do this for all modules which don't have
-  debug info via the `Auto Download Debug Info` setting. The local cache path
-  and server URLs used by the debugger for downloading symbols are parsed from
-  the `_NT_SYMBOL_PATH` environment variable. If that environment variable is
-  not configured, then it falls back to the defaults of `C:/SymbolCache` and
-  `https://msdl.microsoft.com/download/symbols`.
-- Adjusted the default dark theme.
-- Made several UI visual improvements.
-- Fixed a few issues relating to offline symbol evaluation (evaluation of
-  symbols in debug info when not debugging); this was sometimes preventing
-  function listers (e.g. used in `Go To Name`) from working when not debugging.
-- Fixed the debugger's snap-to-code-location rule when a `Disassembly` tab is
-  occupying the same panel as source code tabs. Previously, the debugger would
-  overly aggressively switch back to source code tabs. Now, it should respect
-  the preference of disassembly correctly.
-- Improved the stability of the step-over-line operation. Our stepping
-  algorithm would sometimes cause spurious (and rarely, non-spurious)
-  access violation exceptions when a thread would try to execute at address
-  `0x38f`. This most regularly surfaced when an exception on one thread (like a
-  breakpoint being hit) would interrupt stepping on another thread. This has
-  been resolved, and stepping in such scenarios should be much more reliable.
-- Fixed some crashes in the PDB -> RDI converter. (#792, #803)
-- Fixed a bug which was sometimes causing a step-over operation to resume the
-  process without catching the target thread after its step completed. (#804)
-- Adjusted evaluation visualizations to include fully qualified symbol names.
-  (#809)
-
-## Linker Changes
-- /OPT:REF Fixed a race in the dead-code-elimination pass where the linker
-  sometimes erroneously removed live sections.
-- Fixed a bug where the linker emitted relocations for empty COFF resource entries,
-  which lead to "relocating against symbol that is in a removed section" errors.
-- Added the /RAD_TYPE_SERVER switch to run the type-dedup pass on object files,
-  producing RRT files that can be passed back on the next link to improve
-  linking speed.
-
-# v0.9.26-alpha
-
-## Debugger Changes
-
-- Added scope ending visualizations to the text view, to display the header of
-  a scope at the closing position of the scope. This can be turned off via the
-  `Cursor Scope End Annotations` setting.
-- Added the ability to evaluate `autos`, which is a collection of expressions
-  that the debugger determines refer to symbols which are being (or about to
-  be) changed by the selected thread.
-- Added source-inline and disassembly-inline visualization of auto expressions.
-  This can be turned off via the `Show Auto Watches In Source / Disassembly`
-  setting.
-- Added the ability to evaluate local static variables unambiguously, when the
-  same name is used for multiple local static variables, even when outside the
-  function containing the local static. This can be done by namespacing the
-  variable name with the containing function, either using a `::` or `.`
-  operator. (#359)
-- Added a setting, `Transient Tabs`, to disable transient tabs being opened,
-  when the debugger automatically snaps to new code locations.
-- Added a setting, `Display Pointer Addresses Before Contents`, to always
-  force the debugger to show pointer addresses before attempting to visualize
-  to what the pointer points.
-- Adjusted the `Step Out` command to perform scope-granularity stepping, rather
-  than only being function-frame-granularity. This uses scope information found
-  in debug info to step out of scopes when possible, rather than always exiting
-  the current function frame. This makes the command much more useful for
-  stepping through larger functions with several scopes of larger work, or for
-  stepping out of loops. (#746)
-- Adjusted the debugger's user & project configuration file behavior to be less
-  idiosyncratic with other programs. Project files are no longer auto-loaded
-  based on the project last loaded during the previous debugger runtime.
-  Creating a new user or project also does not immediately require choosing a
-  path for the file; these can later be specified using the respective `Save`
-  commands. (#743)
-- Adjusted the debugger to automatically set the current path when loading a
-  project file. (#743)
-- Added syntax highlighting and tab-completion for view identifiers in
-  watch expressions.
-- Added more in-debugger documentation for views and their arguments, when
-  written in a watch expression.
-- Moved configuration data previously treated as project data to being user
-  data, tagged with the associated project. This includes loaded debug info and
-  breakpoints. The effect of this is that project files are much easier to
-  check into source control (they do not change in spurious ways for other
-  users on a project), but project-related user configuration will still be
-  correctly filtered based on whatever project is loaded.
-- Improved the debugger's behavior with respect to keeping previously-loaded
-  debug info around. Now, when the debugger begins a new debugging session, it
-  will unload all loaded debug info, and it will only reload debug info that is
-  actively found to be needed by debuggees. This preserves the debugger's
-  ability to use debug info without debugging for features like
-  go-to-definition and type evaluation, but it stops the debugger from keeping
-  old and unneeded debug info loaded indefinitely (until it is manually
-  unloaded). (#711)
-- Adjusted recent project visualization to include the name of the project,
-  specified with the `Project Name` setting.
-- Renamed `Switch` to `Open Source File From Debug Info`, to better represent
-  the command's functionality.
-- Adjusted file path evaluation visualization to include the full path to the
-  containing folder, when it is not obvious from context (for instance, if the
-  file evaluation is a child evaluation of a folder evaluation, the containing
-  folder path is not shown; if the file path is evaluated standalone, as it is
-  in the lister generated for the `Open Source File From Debug Info` command,
-  then the containing folder path is shown).
-- Improved visualization of unmapped addresses in the memory view. Now, instead
-  of bytes at these addresses being displayed as `0` with a special background,
-  they are displayed as `x`, and the annotations for these addresses (displayed
-  at the bottom of the memory view, for the cursor's cell) explicitly label
-  them as being unmapped.
-- Improved visualization of unmapped addresses in watch expressions. Now,
-  instead of only being colored differently with evaluations reading as zeroed
-  memory, the value will explicitly label addresses as unmapped when possible.
-- Fixed a leak which most notably manifested during rapid creation/destruction
-  of new threads. (#780)
-- Fixed a leak related to debugger's config state. This was difficult to
-  reproduce, but it may fix leaks experienced after running the debugger for an
-  extended period of time.
-- Fixed a bug where cross-module evaluations would resolve to incorrect
-  addresses, due to using the incorrect module's base virtual address. This was
-  also causing broken behavior sometimes in the `Go To Name` lister, and
-  other similar UIs.
-- Fixed a bug where panels without tabs were unnecessarily keeping the debugger
-  UI awake in some cases.
-- Fixed a bug preventing hover evaluation from working on indexing expressions.
-  (#707)
-- Replaced the DWARF -> RDI converter with a new multithreaded version, which
-  should execute much faster on larger DWARF debug info, and produce much
-  smaller RDI output, due to the addition of type deduplication.
-- Introduced structured namespaces to RDI, which structurally encode namespace
-  hierarchies for debug info symbols, instead of this information being
-  implicitly baked using language-specific conventions into symbol names. This
-  is used to deduplicate repeated namespace prefixes from symbol names, leading
-  to a smaller string footprint for generated RDIs. Symbols now only store
-  their partially-qualified name. For example, for a C++ symbol `A::B::C`, the
-  symbol itself will store its name as `C`, but it will also record its
-  container as being `B`. `B`, then, will record its container as being `A`.
-  This allows users of RDI to dynamically construct the fully-qualified name as
-  needed, and it allows for more reliable and language-agnostic usage of
-  partially-qualified symbol names.
-- Adjusted the debugger to not rely on `SynchronizationBarrier` functions on
-  Windows when they're not available (pre-Windows-8). (#739)
-
-
-## Linker Changes
-
-- Implemented /DEBUG:GHASH
-- Fixed an issue where an import thunk or import address could be linked from
-  the currently searched library instead of the library where the first import
-  reference was found. For example, if the first pass finds the import thunk in
-  foo.lib and the second pass resolves symbol to the import address in bar.lib,
-  the linker now always linkes the import thunk and import address members from
-  the library where the first reference was found.
-- /OPT:REF:  Fixed an issue with garbage collection of associated sections and
-  weak symbols that led linker to remove live sections.
-- /OPT:REF Added relocation batching to reduce contention on the global
-  reference list during garbage collection.
-
-# v0.9.25-alpha
-
-## Debugger Changes
-
-- Added a dedicated cursor address bar to the memory view. This can be focused
-  with the keyboard with the `Focus Menu` command. By default, this command is
-  bound to `Alt + D`, but if you have existing configuration, you may need to
-  bind it yourself manually (this can be done in the palette). This address bar
-  accepts any expression, and controls the cursor's address. All other
-  configuration options are still available in the memory view settings.
-- Added "Peek Types" to the memory view. These control the set of types which
-  are used to interpret bytes at the cursor. Options exist for basic cases,
-  like integers and floats, but the view also supports entering a list of
-  full type expressions, which can include user-defined types like structures.
-- Added annotations for members of structure variables to the memory view.
-- Added a dedicated zoom setting for the memory view.
-- Added a setting for automatically determining the number of columns in the
-  memory view based on the available space.
-- Fixed many bugs and improved visuals in the memory view. (#690)
-- Fixed the debugger incorrectly evaluating pointer casts of registers in
-  register space, rather than promoting them to process address space
-  evaluations. This fixes cases where expressions like `(int *)rax` were not
-  evaluating correctly. (#659)
-- Fixed the debugger incorrectly requiring multiple step operations when source
-  lines mapped to multiple discontiguous ranges of instructions. This most
-  notably showed up with certain styles of `for`-loops, especially with Clang
-  and other non-C/C++ languages, and function prologues in non-C/C++ languages.
-- Fixed the debugger treating the `foo, x` fastpath for `hex(foo)` differently
-  than `hex(foo)`, in that the hexadecimal setting was not being inherited.
-- Fixed the debugger leaking debug info conversion process handles. This
-  addresses cases where the debugger was preventing stale debug info from being
-  updated, after a rebuild. (#736)
-- Fixed the debugger not correctly using target-embedded markup data. (#702)
-- Fixed the debugger not showing full call stacks when the top instruction
-  pointer is located at a 0 address.
-- Fixed integer casts producing incorrect values. (#754)
-- Fixed the PDB -> RDI converter's interpretation of certain empty argument
-  lists in function types in PDB. This fixes some cases where local variables
-  were being interpreted as parameters, which resulted in incorrect evaluation
-  results. (#751)
-- Fixed several crashes and instabilities. (#735)
-- Added a dedicated settings button to the focused tab. This opens the same
-  menu as right-clicking the tab, but this makes this menu (and thus all
-  options for all tabs and views) more discoverable.
-- Added optional cursor trails, to visualize cursor motion. Can be turned off
-  by toggling the `Cursor Trail` setting.
-- Added project names. When set, this name is used for displaying the project
-  instead of the project filename in the UI and window titles.
-- Adjusted the rules for explicit file location finding commands (like
-  `Switch`, or `Switch To Partner File`), such that they prefer creating new
-  non-transient tabs, even if the target file is found within an existing
-  transient tab.
-- Adjusted the source code context menu to activate commands with a single
-  press, rather than the usual double click behavior from general palettes.
-
-## Linker Changes
-
-- Optimized debug info generation to reduce memory usage in large links by 25%.
-- Fixed a determinism issue that caused linker to write unreliable debug info.
-- Fixed over-reservetaion of PDB pages, reducing the PDB size. 
-- Implemented /INFERASANLIBS
-- Implemented /WHOLEARCHIVE
-- Implemented /PDBSTRIPPED
-- Set correct defaults for unload and bind import tables.
-
-# v0.9.24-alpha
-
-## Debugger Changes
-
-- Added the ability for the debugger to load, use, and evaluate using debug
-  info, even when not actively debugging. The debugger will now keep a process'
-  debug info loaded, even after the process ends. It stores the set of loaded
-  debug info files in the project configuration file, meaning it will also
-  automatically load the same debug info across many runs. Debug info can also
-  be loaded manually (without ever launching a process) with the
-  `Load Debug Info` command. There is also a new tab, `Debug Info`, which allows
-  viewing and managing the set of loaded debug info files.
-- Improved the debugger's behavior when used as a drag & drop target, to allow
-  for debug info loading as an option (when relevant), and to better handle the
-  case where many files (potentially of different types) are dropped together.
-- Improved debug info searching performance and reponsiveness in large projects.
-- Fixed some crashes and incorrect results with the new `list` view.
-- Fixed some cases where RDIs did not contain some basic types from their
-  originating PDBs.
-- Allowed `.` and `->` operators to be used with array types.
-- Fixed the debugger's treatment of quoted command line arguments when building
-  targets. In previous versions, calling `raddbg main.exe "foo bar baz"` would
-  create a target `main.exe` with arguments `foo bar baz` (dropping the quotes).
-  This is now fixed, such that the target's arguments string will also contain
-  the quotes, and pass them to the target when launched.
-- Fixed the debugger not correctly responding (through font and UI scale) to DPI
-  changes.
-- Fixed the debugger incorrectly generating conflicting source line info records
-  in PDB -> RDI conversion, which in some scenarios was preventing source line
-  maps from working (leading to breakpoint resolution failing).
-- Other small fixes, improvements, and tweaks.
-
-# v0.9.23-alpha
-
-## Debugger Changes
-
-- Further improved PDB -> RDI conversion performance & memory usage.
-- Adjusted limits for the amount of PDB -> RDI conversion work that the
-  debugger will kick off, to prevent PDB -> RDI conversion interfering with
-  debuggee performance.
-- Reintroduced the `list` lens, which gathers all nodes in a linked list, and
-  visualizes them as a flat list of pointers (the same as how an array of
-  pointers is visualized).
-- Fixed a crash when closing empty Geometry 3D views. (#652, #657)
-- Fixed the debugger not visualizing `enum` types when evaluated through a
-  bitfield type. (#655)
-- Fixed the PDB -> RDI conversion not correctly generating location information
-  for function parameters, when the EXE/PDB were built to include support for
-  Edit and Continue (`-ZI` switch). (#656)
-
-## Binary Utility Changes
-
-- Fixed a crash when using the `--compress` option, when generating RDI files.
-
-# v0.9.22-alpha
-
-## Debugger Changes
-
-- Further improved PDB -> RDI conversion performance.
-- Capped the number of additional threads / processes spawned for PDB -> RDI
-  conversion.
-- Prioritize PDB -> RDI conversion based on what is actually found to be
-  necessary by the debugger, rather than converting all PDBs in the order in
-  which they're discovered.
-- Added preliminary support for DWARF -> RDI conversion on Windows.
-- The debugger now relies on source file checksums to determine whether or not
-  a source file is out-of-date with respect to what was compiled when debug info
-  was produced, rather than just the modification timestamp.
-- The debugger now will rely on debug info to detect the language of source code
-  files, if it cannot infer from the source file's extension, or view settings.
-  This will enable features like syntax highlighting and hover evaluation in
-  cases like `.inl` files being included in C++ projects.
-- The debugger now will restore the last focused window when continuing
-  automatically. (#245, #596)
-- Watch tables have been simplified in that they no longer have a separate
-  column for evaluation types, since this was usually taking a lot more space
-  than it deserved. The type of evaluations is still displayed in watch table
-  cells, and it can always be evaluated directly via `typeof`.
-- Type evaluations have been simplified in watch tables as well; they no longer
-  have untitled columns for sizes and offsets, this is instead displayed as
-  an extra note by default. Similar behavior to the original behavior can still
-  be obtained using the `columns` view, if needed.
-- The debugger no longer uses complex `union` types for most registers, and
-  instead just displays the register value plainly.
-- The hover evaluation UI has been made larger when needed.
-- The debugger now prefers matching global, function, and type identifiers to
-  the most relevant debug info and module in context; this fixes evaluation in
-  some multi-process debugging contexts. (#581)
-- Fixed the debugger unnecessarily stripping `enum` type information when
-  accessed through array operators. (#634)
-- The debugger now understands a standalone `unsigned` keyword as an
-  `unsigned int` type, to match C rules.
-- The debugger now uses the current working directory to form the working
-  directory for targets specified on the command line, to match behavior when
-  running a command from the command line without the debugger.
-- Improved call stack computation performance.
-- Improved debugger memory usage over long periods of time.
-- Fixed string-pointer comparison not working with not-equal (`!=`) operations.
-- Fixed a bug which was causing bad debuggee performance on some threads after
-  some interactions with the debugger controller.
-- Fixed incorrect results when adding two register values. (#642)
-- Fixed the interpretation of register expressions in visualizers. (#649)
-- Fixed "forever loading" states in disassembly views in some cases. (#643)
-- Fixed jittering on window resizing. (#636)
-- Fixed the bitmap visualizer crashing in some circumstances relating to
-  unsupported bitmap sizes. (#444, #563)
-- Fixed a crash when an empty `cast()` expression would be evaluated. (#625)
-- Fixed a crash when an invalid expression would be visualized using the `text`
-  view. (#647)

-## Linker Changes
-
-- Changed symbol resolution in libaries to match MSVC behavior.
-- Optimized image building step to reduce memory usage.
-- Linker memory maps all input files by default to lower memory usage.
-  (`/RAD_MEMORY_MAP_FILES`)
-- If debug info is available, linker uses it to show file and line number for
-  unresolved relocations.
-- Improved base relocation build performance for large images, cutting build
-  time by 70%.
-- Added stubs for `/Brepro`, `/D2`, and /ErrorReport to improve compatability
-  with existing response files
-- Implemented section garbage collection (`/OPT:REF`)
-- Fixed bug where thread local variables pointed to incorrect types.
-- Changed rules for weak and undefined symbols, now weak symbol is not allowed
-  to replace an undefined symbol.
-- Linker no longer creates thunks for imports that don't require them.
-
-## Binary Utility Changes
-
-- The binary utility, like the debugger, now can convert DWARF debug info to
-  RDI files. When both DWARF and PDB info is present, it can now convert both,
-  and produce a single final RDI file with all information.
-- Textual dumping of RDI files is now done in parallel, massively improving
-  dumping performance.
-- PDB -> Breakpad conversion performance has now been parallelized to a greater
-  degree, improving performance.

-debugger itself, and is intended as a technical overview of the project. The

 The RAD Debugger is a native, user-mode, multi-process, graphical debugger. It
 currently only supports local-machine Windows x64 debugging with PDBs, with
 plans to expand and port in the future. In the future we'll expand to also
 support native Linux debugging and DWARF debug info.
 
-The debugger is currently in *ALPHA*. In order to get the debugger
-bullet-proof, it'd greatly help out if you submitted the issues you find
-[here](https://github.com/EpicGames/raddebugger/issues), along with any
-information you can gather, like dump files (along with the build you used),
-instructions to reproduce, test executables, and so on.

-In addition to the debugger, we aim to further improve the toolchain with two
-additional related technologies: **(1)** the RAD Debug Info (RDI) format, and
-**(2)** the RAD Linker.
+You can download pre-built binaries for the debugger
+[here](https://github.com/EpicGames/raddebugger/releases).
 
-## The RAD Debug Info (RDI) Format
+The RAD Debugger project aims to simplify the debugger by simplifying and
+unifying the underlying debug info format. In that pursuit we've built
+the RADDBG debug info format, which is what the debugger parses and uses. To
+work with existing toolchains, we convert PDB (and eventually PE/ELF files
+with embedded DWARF) into the RADDBG format on-demand. This conversion process
+is currently an unoptimized reference version. Nevertheless it's still quite
+fast for smaller PDB files (in many cases faster than many other programs
+simply deserialize the PDBs). It is much slower for much larger projects at the
+moment, but we expect this will vastly improve overtime.
 
-The RAD Debug Info (RDI) format is our custom debug information format, which
-the debugger parses and uses, rather than the debug information natively
-produced by toolchains, like PDB or DWARF. To work with these existing
-toolchains, we convert PDB (and eventually PE/ELF files with embedded DWARF)
-into the RDI format on-demand.
+The RADDBG format is currently specified in code, in the files within the
+`src/raddbg_format` folder. The other relevant folders for working with the
+format are:
 
-The RDI format is currently specified in code, in the files within the
-`src/lib_rdi` folder. In [`rdi.h`](src/lib_rdi/rdi.h) and
-[`rdi.c`](src/lib_rdi/rdi.c), the types and functions which define the format
-itself are specified. In [`rdi_parse.h`](src/lib_rdi/rdi_parse.h) and
-[`rdi_parse.c`](src/lib_rdi/rdi_parse.c), helpers for parsing the format are
-included.
+- `raddbg_cons`: The RADDBG construction layer, for constructing RADDBG files.
+- `raddbg_convert`: Our implementation of PDB-to-RADDBG (and an in-progress
+implementation of a DWARF-to-RADDBG) conversion.
+- `raddbg_dump`: Code for textually dumping information from RADDBG files.
 
-We also have an in-progress library for constructing and serializing RDI data,
-located within the `src/lib_rdi_make` folder.
+## Development Setup Instructions
 
-Our `radbin` utility (accessible through the debugger too, via the `--bin`
-command line argument) is capable of converting native debug information formats
-to RDI, and of producing textual dumps of contents stored within RDI files.
+**Note: Currently, only x64 Windows development is supported.**
 
-## The RAD Linker
-
-The RAD Linker is a new performance linker for generating x64 PE/COFF binaries.
-It is designed to be very fast when creating gigantic executables. It generates
-standard PDB files for debugging, but it can also (optionally) natively create
-RAD Debug Info too, which is useful both to eliminate on-demand conversion time
-when debugging, but also for huge executables that otherwise create broken
-PDBs that overflow internal 32-bit tables.
-
-The RAD Linker is primarily optimized to handle huge linking projects. In our
-test cases (where debug info is multiple gigabytes), we see 50% faster link
-times.
-
-The command line syntax is fully compatible with MSVC; you can get a full list
-of implemented switches from `/help`.
-
-Our current designed-for use case for the linker is to help with the
-compile-debug cycle of huge projects. We don't yet have support for
-link-time-optimizations, but this feature is on the road map.
-
-By default, the linker spawns as many threads as there are cores, so if you plan
-to run multiple linkers in parallel, you can limit the number of thread workers
-via `/rad_workers`.
-
-We also have support for large memory pages, which, when enabled, reduce link
-time by another 25%. To link with large pages, you need to explicitly request
-them via `/rad_large_pages`. Large pages are off by default, since Windows
-support for large pages is a bit buggy; we recommend they only be used in Docker
-or VM images where the environment is reset after each link. In a standard
-Windows environment, using large pages otherwise will fragment memory quickly,
-forcing a reboot. We are working on a Linux port of the linker that will be able
-to build with large pages robustly.

+## Short-To-Medium-Term Roadmap
 
 ### The Initial Alpha Battle-Testing Phase
 
-The first priority for the project is to ensure that the most crucial components
-are functioning extremely reliably for local, x64, Windows development.
-For the debugger, this would include parts like debug info conversion, debug
-info loading, process control, stepping, evaluation (correct usage of both
-location info and type info), and a robust frontend which ensures the lower
-level parts are usable. For the linker, this is a matter of reliability and
-convergence with existing linker behavior.

-We feel that we've already come a long way in all of these respects, but given
-the massive set of possible combinations of languages, build settings,
-toolchains, used language features, and patterns of generated code, we still
-expect some issues, and are prioritizing these issues being resolved first.
+We feel that the debugger has already come a long way in all of these respects,
+but given the massive set of possible combinations of languages, build
+settings, toolchains, used language features, and patterns of generated code,
+there are still cases where the debugger has not been tested, and so there are
+still issues. So, we feel that the top priority is eliminating these issues,
+such that the debugging experience is rock solid.
 
-We also hope to continue to improve performance in this phase. For the debugger,
-this primarily includes frontend performance, introducing caches when economical
-to do so, and tightening existing systems up. For the linker, it has been mostly
-tuned thus far for giant projects, and so we'd like to improve linking speed for
-small-to-mid sized projects as well.
-
-For the linker, there are also a number of features to come, like
-dead-code-elimination (`/opt:ref`), and link-time-optimizations with the help
-of `clang` (we won't support LTCG from MSVC, since it is undocumented).
+Additionally, the debug info conversion process is not fast (nor wide) enough
+to support extremely large projects. This is for two reasons: (a) the
+PDB-to-RADDBG converter is an unoptimized reference implementation, and (b) the
+debugger learns of new modules (and thus which PDBs to load) in a
+serially-dependent way (this is necessarily the case for correct debugging
+results). We expect that the conversion process' performance can be massively
+improved, and also that some heuristics can be used to begin converting PDBs
+to RADDBGs before the debugger knows those PDBs are needed, thus ensuring the
+associated RADDBG files are ready instantaneously when the associated modules
+are finally loaded by the debugger. Improving this situation is a major part of
+this phase, as it will make the debugger much more usable for large projects.
