So as you can see from the notice above, (
https://bitcointalk.org/index.php?topic=2702103.0 )
Electrum is vulnerable, and has been for quite a while. Its just that they have discovered it now, and also that their first fix wasn't a fix either, that have upgraded it again.
I for one am not feeling much better after this upgrade either, because tomorrow maybe another one like this.
So is it time to move from electrum to another option?
What do you guys think?
Electrum is a great wallet.
A vulnerability may be found in any wallet (even in a hardware one, Ledger is an example).
IMHO no point of moving from Electrum if you are satisfied with it.
A finding of a problem with Electrum 3.03 and earlier certainly is a reason to move from those versions of Electrum. Logically that would be to later versions of Electrum that do not have the problem.
Note that for certain cold storage applications it's required to not be updating the programs used say in an air gapped computer.
