-- Highlighting/completions/command history don't work as I expect in the
-  Integrated Console - [#535]
-  - The Integrated Console implements a [custom host]
-    to work with VSCode, meaning that functionality could be different than that of the regular host in the PowerShell Console
-  - [PSReadLine] (the module providing these features in regular PowerShell) is available in the PowerShell Preview Extension, helping to bridge this gap
-  - Making PSReadline fully available is being actively worked on.
-- Command history is not preserved when debugging in the Integrated Console -
-  [#550]
-  - This feature is also provided by [PSReadLine].
-- Intellisense is slow - [#647]

+  - Do you use Avecto/BeyondSoft?
+    We've received reports that Avecto, BeyondSoft

 - Variable renaming doesn't work properly - [#261]
   - PowerShell's usage of [dynamic scope] rather than [lexical scope]
     makes it [formally undecidable] to statically rename variables correctly

   - Check that the dialog hasn't opened behind VSCode. This is a known

 - PowerShell classes don't have proper reference/symbol support - [#3]
-  - To maintain compatibility with PowerShell v3/v4 we use an older
-    PowerShell parsing API that does not support classes. A future version
-    of the [PowerShell Extension] [will break this compatibility] to support
-    classes, among other things.
+  - One of the blockers for this was that we still supported Windows PowerShell v3 and v4. However, we don't support v3 and v4 anymore so we can do this work but it's not on the roadmap at this time.
 - Document formatting takes a long time - [#984]
   - Document formatting is provided by [PSScriptAnalyzer], but there
     may be opportunities to improve our integration with it in the
     [PowerShell Extension] too.
