Update to 2.0.13:

Changes in 2.0.13

    Sibling handling has been reworked, which should better ensure
    that cards from the same note donât appear together:

	When you answer a card, Anki will automatically bury any
	siblings that are in the new queue or review queue. Cards
	in the (re)learning queue can not be buried, but reviewing
	those cards will cause any new & review cards to be buried.

	Cards are no longer unburied when returing to the deck
	list, but can be unburied with a button on the study overview
	screen.

	To avoid problems during the upgrade period, cards are
	currently unburied when you sync or close your collection.
	When all clients have been updated, this behaviour will
	change so that cards are only automatically unburied when
	a day has passed. You will still be able to manually unbury
	them if you wish.

	This new behaviour ensures that siblings are spaced even
	in filtered decks.

	Burying of new cards can be disabled in the options if you
	want to introduce related cards in the same session. If
	disabled, Anki will try to spread out the siblings like it
	does in 2.0.12, though like 2.0.12 spacing is not guaranteed
	and may fail when you edit cards or perform operations that
	require a queue rebuild.

    When importing an .apkg file, existing notes will be updated
    if they are newer in the .apkg file, and the note types are
    compatible. Cards are not touched, so existing progress will
    be retained. This means content authors can now easily distribute
    not only new content, but updates to existing content as well.

    Filtered decks have a new "relative overdueness" sort option
    that will sort cards by how overdue they are compared to their
    interval, in the same manner Anki did a few years ago.

    You can now show tags as a browser column.

    Fix an issue with importing when a filtered deck was selected
    in the main window.

    Donât treat modified q/a templates as an incompatible note
    type.

    Anki now enforces a standard encoding of media files with
    non-latin text, which should fix some issues moving media
    between Mac and non-Mac computers, and will ensure you donât
    end up with multiple files in your media folder that look like
    they have the same filename but actually have a different
    encoding.

    The unused media menu option has been renamed back to "Check
    Media", and it is now capable of renaming fields and media
    filenames to ensure theyâre consistent.

    Fix an issue where dragging files from the desktop on Linux
    was pasting a URL instead of embedding the file

    Fixed a bug where Anki failed to start on Linux distributions
    with an older Python version.

    Anki now allows you to import .apkgs which have been renamed
    to .zip, as unfortunately some browsers "helpfully" rename the
    files when downloading them.

    The "Find Duplicates" function in the browser now ignores HTML
    when comparing duplicates, and provides an option to tag the
    duplicates.

    Fix an error in showing an error when downloading addons

    Fix < and > in a field causing text to disappear when typing
    in the answer .

    The "study deck" and deck/note type selection windows now
    remember their size and position.

    Fix an issue showing clozes when the userâs mistyped the cloze
    characters.

    Tolerate Windows trash errors .

    Fix an error when upgrading some Anki 1 decks.

    Separate users on the same machine can now run Anki concurrently.

    Anki should no longer have issues starting upon Linux after a
    previous instance didnât terminate properly.

    Fix some issues with suspending, burying & rescheduling learning
    cards that could cause a later "download the fix assertion
    addon" message.

    After syncing once, the sync username should become visible in
    the preferences dialog.

    When adding a new column in the browser, scroll it into view.

    When adding or importing note types, ensure they have a unique
    name.

    Speed improvements to some text operations, thanks to hssm.
