From the comparison published on Wednesday, signage applies still for "preventing" carry.
(Recall there's no exception under 30.06 or 30.07 for licensed carry within user-prohibited locations)
LTC will remain, remains $30 (as far as I can tell), and is largely for out-of-state reciprocity. Also, LTC still makes NICS check redundant
Also the current version also removes the shoulder holster or belt holster language from the "open carry" portions of the law. This will moot the separate bill already out of conference to explicitly deal with this.
The RFL, No private Transfers, required liability, requirement to declare, and required safe storage "poison pills" introduced in the Senate have all been excised.
Most of the debate in the senate was over the language about open carry in vehicles. Which may be clarified to mean you no longer have to conceal a firearm carried in your vehicle (only those carried on public carriers--bus, taxi, uber, etc.--where permitted by that carrier).
