From this version this mono repo switches to independend Lerna mode - this means that when 2 packages are updated at the same time, they could be updated to a different version.

Regarding updates for redux-saga-requests package:

• POTENTIALLY BREAKING: changed the way success, error, abort actions are structured, see actions and FSA in readme
• added getError option to requestsReducer
• added Actions and FSA blocks to readme
