# Non-Technical Summary
+

                      
+
Controlling bug fixes from the previous week worked as expected in order to 
+
aim for a very stable release on the beginning of the following week. We've 
+
also continued the work on the new Haskell node integration, closing the gap
+
on the missing API endpoints from the integrated wallet. It is now a matter 
+
of performing deep integration tests and analysis to ensure that the integration
+
is indeed a full success.
+

                      
+
# Overview

[v2020-01-27](https://github.com/input-output-hk/cardano-wallet/tree/v2020-01-27) | [v0.8.7](https://github.com/input-output-hk/jormungandr/releases/tag/v0.8.7)

+
## :heavy_check_mark: Completed
+

                      
+
- Improve the reporting of pending delegation certificates
+
  to better for wallet going through frequent delegation changes.
+
  The current version only reported the most recent pending 
+
  delegation certificates, whereas, there can be at most two 
+
  pending certificates by design, which are now correctly reported.
+

                      
+
- Provide a real implementation for the LocalTxSubmission protocol
+
  on the byron's node integration. This enables us to start doing 
+
  some deeper integration testing, with as a first goal, the replication
+
  of all the existing integration integration test scenarios currently
+
  running on Jörmungandr. 
+

                      
+
- Deep re-organization of JIRA product backlog trying to better
+
  align workflows between the Adrestia's team and Cardano's.
+

                      
+
- Started writing engineering specifications about address derivation
+
  and mnemonic manipulation and root key generation from mnemonic 
+
  sentences. 
+
