Update Information

Since a lot in the config.json has changed, you can either remove/move the existing config.json and copy/paste from config.example.json what you need into the new one, or vice-versa. Regarding the bug fix: Essentially the `active_key` was missing as a parameter and a variable (`set_properties`), which is needed for the code to know whether it should sign with private signing-keys (new feature in HF20) or via active-key, wasn't set correctly. See below for the code. ``` # before transaction_signing_key = essentials.choose_transaction_key(_g.CURRENT_SIGNING_KEY, g.config.SIGNING_KEYS) ... more code set_properties = true # after transaction_signing_key = essentials.choose_transaction_key(_g.CURRENT_SIGNING_KEY, _g.config.ACTIVE_KEY, _g.config.SIGNING_KEYS) ... more code set_properties = transaction_signing_key !== _g.config.ACTIVE_KEY ``` --- All right, that's it for the much-needed update (1.0.1 was released 4 months ago), but at least over all that time, the pricefeed worked flawlessly. :) So, I hope my fellow witnesses find this useful and if there are any questions, let me know. All the best, Wolf ---
