Describe changes:

• Disable swf decompression by default
• Add entry in upgrade.rst noting the change and linking to the ticket

Since disabling swf decompression by default is actually not related to how we do lzma decompression (#8132), we can separate these changes.

Could you rebase this on latest master please ?
That should at least fix the CI Check Rust...

Looks fine otherwise

Can you reference the ticket in the commit? Ticket: #xxxx. on its own line.

Also, what happens in case the option is not in the yaml at all? Is it disabled then?
