Qt Creator 4.15.0

What's new in this version:

General:
- We added a locator filter for opening files from anywhere on your disk. This locator filter was already available on macOS using Spotlight. Now it also is available on Linux and Windows, and can be configured to use any external command line tool that returns a list of files. The default setting is using "locate" on Linux and "everything" on Windows.
- Sometimes it is difficult to configure the environment variables that are set when Qt Creator is run, which in turn affects external tools run from Qt Creator. We added a global option for this in Tools > Options > Environment > System > Environment. This adapts the system environment which is then further modified by the kit environment, the build environment, and the run environment.
- If you have issues with the encoding of tool output in Qt Creator on Windows, you can now set the encoding that Qt Creator uses for this in Tools > Options > Environment > Interface > Text codec for tools.

Editing:
- Please see our change log for the long list of fixes that were done for the C++ support. I'll just mention here that you now can filter the result of searching symbol usages by access type.
- The QML editor can handle inline components now, and received some more fixes for advanced JavaScript features.
- Our client for the Language Server Protocol got support for versioned diagnostics, progress messages, and new formatting options in protocol version 3.15.0 (if your language server provides these). We also simplified the configuration of a Java language server, and generally improved support for it.

Projects:
- We fixed several issues that made it hard to configure CMake projects that have special prerequisites to successfully parse at all. Aside from multiple other fixes, Qt 6-based CMake projects can now also target iOS.
- Speaking of iOS, we finally fixed deployment to iOS 14 devices.
- There is a new option for running applications as root from Qt Creator.

Debugging:
- We added the option to show simple values of variables inline in the text editor, while debugging. Turn this option on or off in Tools > Options > Debugger > General > Use annotations in main editor while debugging.
- Please check our change log for a more complete list of improvements.
- A note on future versions: Qt Creator 4.15 will be the last release in the Qt Creator 4.x series. Our summer release will be Qt Creator 5 and our winter release Qt Creator 6, followed by 7, 8, and so on. That does not mean that we are rewriting Qt Creator so much, but simply that we change our versioning scheme to semantic versioning.
