Legacy addon support - can still be signed after Firefox 57?

Hi,

Can anyone help to explain what the following message means to legacy add-ons?
Does it mean that as developer we can still submit update for signing, in order to be used on Firefox versions before 57? Thanks in advance!

In blog "The Road to Firefox 57"
“AMO will continue to support listing and updating legacy add-ons after the release of 57 in order to have an easier transition. The exact cut-off time for this support hasn’t been determined yet.”

Yes, you’ll still be able to upload updates for signing up to Firefox 57 (and for a while after then).

Thank you Jorge!
This surely will make our life easier.
