Could someone please clarify this statement from above? "We are planning on moving to BIP 32 which will thus deprecate the currently used stuff. However the legacy wallet systems will likely still be kept for backwards compatibility."
Does this mean that at some point the older paper backups will not be restorable into the newer clients?
Yes.
Has this happened yet?
No. We have not moved to BIP 32 yet. Once we do, it will still be a few versions before the legacy wallets are phased out entirely.
I also have some questions of compatibility around bitcoin core and Armory.
Currently, I have Bitcoin core 15.1 installed and finishing the sync of the blockchain. My main reason for updating was to take advantage of the big initial sync performance improvements. I'm now not 100% sure which versions of Armory support this.
For example, 96.0 says it supports 14.0+, does this mean 14.x only or does it include 15.x?
0.15.x is greater than 0.14, so it is supported. However you should use the latest version of Armory anyways, 0.96.3 or 0.96.4 RC1.
I'm running OSX and have Armory 95.1 installed, it seems 96.1 is the latest that has OSX support, is that correct?
0.96.3 has OSX binaries that I forgot to list on the website. You can get them from here:
https://github.com/goatpig/BitcoinArmory/releases/tag/v0.96.3. You could also use 0.96.4 RC 1 which has a few bug fixes, available from here:
https://github.com/goatpig/BitcoinArmory/releases/tag/v0.96.3.99Lastly, is there any danger in restoring into a slightly older version of Armory. E.g, if I restore into 95.1, is this ok?
It should be fine, but the older versions have a variety of bugs and performance issues that were fixed in the new versions.
