Communication Channels
-----------------------
contributions but rather understand the project culture before investing an
asymmetric number of hours on development compared to your merged work.
-Browsing through the [meeting minutes](https://github.com/lightningdevkit/rust-lightning/wiki/Meetings)
+Browsing through the [meeting minutes](https://github.com/lightningdevkit/rust-lightning/wiki/Meeting-Notes)
is a good first step. You will learn who is working on what, how releases are
drafted, what are the pending tasks to deliver, where you can contribute review
bandwidth, etc.

+## API Updates
+- The functions `inbound_payment::{create, create_from_hash}` and
+ `channelmanager::{create_inbound_payment, create_inbound_payment_for_hash}` now accept a
+ `min_final_cltv_expiry_delta` argument. This encodes the `min_final_cltv_expiry_delta` in the
+ payment secret metadata bytes to be validated on payment receipt.
+
+## Backwards Compatibility
+- If `min_final_cltv_expiry_delta` set for any of `inbound_payment::{create, create_from_hash}` or
+ `channelmanager::{create_inbound_payment, create_inbound_payment_for_hash}` then the payment will
+ not be receivable on versions of LDK prior to 0.0.114.
