v0.9.0-1: (Still) Rat Poison Squared on Steroids

This is a point release addressing some minor issues that slipped through with the v0.9.0 release, mainly due to the rewrite of the `pay` plugin for multi-part payment support. For details on the changes included in this point release please refer to the tracking issue #3928. We suggest upgrading to this version if: - You are using a wallet that shows incorrect information due to missing fields in the RPC responses. - Larger payments above 10,000 satoshis to non-public nodes fail due to the destination being unreachable. We apologize for the inconvenience, and thank the community for the extensive testing and feedback so far. -- Christian
