Will Electrum stay backward compatible?

I was using electrum 2.6.4, and my question is will it stay backward compatible?

    ●  I am not referring to the wallet format, but the seed & master priv key and master public key structure? Will a new electrum say 3.x.x be able to recognize the seed of a 2.6.4 wallet?

    ● Will the electrum servers load up a 2.6.4 wallet say 1 year from now?

How long will old versions be compatible?

First of all, the old version of Electrum has always been available either on
GitHub: https://github.com/spesmilo/electrum/releases
or official website: https://download.electrum.org/
so you can download and use those if you wish.


So far the new versions have always been backward compatible meaning they recognize the older version of wallet.dat and/seed seed and can convert it to the newer version.


So far it does. And for the future, it should continue doing so.


I don't understand what you mean by this.

If I load up an older wallet, even pre 2.x.x say 1 year from now, will the electrum servers fetch the required data and be able to do transactions on them.

(I suppose the electrum server itself will accept any request from any older electrum client, is this true?)

As long as are people using lower versions of electrum and not having problems (although these persons are very few nowadays) it should continue to accept requests and continue to operate normally until noted otherwise. A comparison I will make with you is, Multibit Classic although abandoned is still working like a charm, so why should Electrum older versions don't ?

Yes it will accept server requests normally.

Always. See first paragraph:
