Which v0.17.1 changes are importand in block analyse?

I am analysing binary blocks.
There are changes:" Litecoin Core v0.17.1" at github.
There are major changes:

  • BIP 174 Partially Signed Litecoin Transactions support
    “Note that the block database format also changed in version 0.8.0 and there is
    no automatic upgrade code from before version 0.8 to version 0.15.0. Upgrading
    directly from 0.7.x and earlier without redownloading the blockchain is not
    supported. However, as usual, old wallet versions are still supported.”

Which changes will be important for me while I don’t use wallet but binary read blocks and transactions?
