[DevTools overview](/tools/devtools/overview).

## General updates

* Improved messaging when a screen is unavailable for the
  platform of the connected app. - [#7958](https://github.com/flutter/devtools/pull/7958)
* Fixed a bug where an infinite spinner was shown upon
  app disconnect. - [#7992](https://github.com/flutter/devtools/pull/7992)
* Fixed a bug where trying to reuse a disconnected DevTools instance would
  fail. - [#8009](https://github.com/flutter/devtools/pull/8009)

## Performance updates

* Removed the "Raster Stats" feature.
  This tool did not work for the Impeller rendering engine, and
  the information it gave for the SKIA rendering engine was
  often misleading and unactionable. Users should follow the
  official Flutter guidance for [Performance and optimization](/perf) when
  debugging the rendering performance of their Flutter apps. - [#7981](https://github.com/flutter/devtools/pull/7981).

## Network profiler updates

* Fixed an issue where socket statistics were being reported as web sockets. - [#8061](https://github.com/flutter/devtools/pull/8061)

* Added query parameters to the request details view. - [#7825](https://github.com/flutter/devtools/pull/7825)

## VS Code Sidebar updates

* Added buttons for all DevTools tools in the sidebar by default, even when
  there are no debug sessions available. - [#7947](https://github.com/flutter/devtools/pull/7947)
