So the update is fully on RPC Wallet API?
Yes, except for some minor changes in Bytecoin GUI Wallet
How stable is the current version?
This is the final version of the API. We are not planning to change anything.
Is it backward compatible?
Yes, Payment IDs are still supported.
2. What are you up to now? When is the next large update?
3. You didn't update the roadmap and v.1.0.9 doesn't correspond with the actual release. When is it going to be updated?
There is indeed a discrepancy in the current 1.0.9 version. We are now working on the 2016 roadmap, which will include all promised features. Moreover, the features under the section "various work in progress" will be also a part of the updated 2016 roadmap.
The updated 2016 roadmap will be published before Christmas.
Also, can you elaborate on what happened to transactions list tab?
The transactions are now expandable... but why? Some of my previous transactions have weird small transfers inside.
From now on transactions are classified differently. Previously, if you created a transaction to be sent to 10 different addresses, you would've seen 10 transactions in the list. But if you create such transaction in 1.0.9, you will see one transaction with 10 transfers inside.
