+# v3.9.0-dev
+
+## Other
+
+- Toolchain: removed he background tool _dastworx_ and replaced it with a library called _libdexed-d_. Although this will not change the user experience:
+    - Thousands of system calls to create the process and read its streams are saved.
+    - ddemangle not required anymore.
+    - crash in the new library will be fatal, i.e the IDE will have to be relaunched, while previously the tool was launched again, without significant impact on the IDE.
+
 # v3.8.4

-## Dastworx
-
-_D AST works_ is a tool that processes the AST of a D module to extract several information used by dexed.
-
-It's notably used by the _symbol list_ and the _todo list_ widgets.
-
-## Build
-
-If dexed is build manually you certainly have to build _dastworx_ too.
-Two options exist.
-
-#### Using dexed & the submodules
-
-- If you've cloned this repository, make sure that the submodule are also here with `git submodule update --init`. 
-- In Dexed open the project `dastworx.dxp`.
-- Select the `release` configuration.
-- Click `Compile project`
-
-#### Using the scripts
-
-- Windows: `build.bat`
-- Linux: `sh ./build.sh`

+* [Download](https://github.com/ldc-developers/ldc/releases) and setup LDC2, the LLVM-based D compiler. It is used to compile the part of IDE written in D, a library called _libdexed-d_. the binaries must be visible in the system PATH variable. Note that building _libdexed-d_ is automatic.

 The Lazarus LCL and the FreePascal FCL may require patches that fix bugs or regressions present in the latest Lazarus release and for which Dexed cannot include workarounds.
 Any `.patch` file located in the `patches/` folder should be applied. On linux you'll have to set the write permissions to `/usr/lib64/fpc` and `/usr/lib64/lazarus`.

 Additionally you'll have to build [the completion daemon **DCD**](https://github.com/dlang-community/DCD#setup) and the [D linter **Dscanner**](https://github.com/dlang-community/Dscanner#building-and-installing).

 This list displays the symbols declared in the D module that has the focus (imports, classes, variables, etc).
-The widget is a GUI front-end for one the [_dastworx_](https://gitlab.com/basile.b/dexed/-/tree/master/dastworx) feature.
 
 It can be used to quickly find and go to the declaration of a symbol but also as a basic linter since the syntactic errors are displayed (almost immediately if the option _refresh on change_ is checked).
