old cryptsetup default is es-cbc-essiv:sha256. the new one is aes-xts-plain64:sha256. i don't know that much about cryptography but i assume the standard was changed for a reason. also there can be found information like:

[...] if your device is still encrypted with the previous (cryptsetup <1.6.0) default cipher --cipher aes-cbc-essiv, more information leakage may occur from trimmed sector observation than with the current default.

so should i upgrade my old encrypted volumes?

That depends, if you have a lot of very sensitive information in a large volume and you need to be as secure as possible then the answer is yes. Otherwise I'd say it is up to you, but I would not lose any sleep over it.
