I am getting a bit confused by the contradictory 'information' put out by various news sites (including Sky).

For the Premier League and Championship the deadline for transfers in - permanent or loan - is 5.00 pm today?

There could be a slight extension to that if the main paperwork has been submitted by the deadline?

Transfers out depend on the deadline for the relevant league - with L1, L2, Scotland and most European leagues having a later deadline than today?

Free agents - this is where I have seen very different claims - can only be registered by a club whilst their transfer window is open? In some places it says free agents can be signed and registered with the league at any time provided they were released by their former club before the window closed. I think it is the former but not 100% confident.
