sess_read,sess_write etc methods are removed from CI3.0 session library

Hey there!,

I was using Ci 2.5 previously and tried to upgrade on ci3.0 but causing some session error, then i researched little bit and found there are some methods has been removed in ci3.0 like "sess_read,sess_write" and maybe more. Can anyone please suggest me any alternate method that can be used here?



Thanks,
