From [the documentation](https://docs.python.org/3.9/library/platform.html#platform.platform):
> Returns a single string identifying the underlying platform with as much useful information as possible.
The output is intended to be human readable rather than machine parseable. It may look different on different platforms and this is intended.
Changed in version 3.8: On macOS, the function now uses mac_ver(), if it returns a non-empty release string, to get the macOS version rather than the darwin version.
The main advantage of this change is that it provides the architecture of the platform, which is increasingly relevant as ARM systems are becoming more common.
The sidebar (QDockWidget) was not restored properly in some environments
when re-opening the browser if the browser was closed while maximized
under the condition that the window size in the normal window state was
very small.
Partially completes #1068, and will allow mobile clients to drop
their separate diff-match-patch imports. Does not yet try to handle
case folding or combining-char stripping, and leaves some of the outer
HTML wrapping up to the frontend for now.
The logic for rendering the provided string has changed: missing chars
are now only inserted if they follow a correct section, and the original
text is shown instead of hyphens. This is an experiment, and can be
changed if it's not well received.
* Refactor MediaManager transactions
* Add media entries when importing
* Fix legacy apkg import not setting csum
Also test for this in the roundtrip test.
* Avoid reallocating MediaCopier's buffer
* Make sha1 optional (dae)
* Add ExportFormat enum and use it in Exporter classes
* Add exporter hooks and call them from new exporters
* Fix filter argument order and add example to docstring
* Refactor: Avoid repeating ExportFormat
* Rename Options to ExportOptions for better namespacing in add-ons
* Add simplified legacy exporter hooks
Allows add-ons to be notified of exports when legacy handlers are enabled, without the need for monkey-patches.
* Switch away from ExportFormat, opting to pass exporter class/instance instead
* Consistently use exporter instances rather than classes
* Revert Exportdialog.exporters rename
* Revert "Revert Exportdialog.exporters rename"
This reverts commit 357a3aa859.
