+This week's newsletter references a discussion about BIP151 encryption
+for the peer-to-peer network protocol, provides an update on
+compatibility between Bitcoin and the W3C Web Payments draft
+specification, and briefly describes some notable merges in popular
+Bitcoin infrastructure projects.
+
+## Action items
+
+{% comment %}<!-- FIXME: this hasn't actually happened yet, but I'm
+expecting it before Tuesday morning -harding -->{% endcomment %}
+
+- **Allocate time to test Bitcoin Core 0.17RC3:** Bitcoin Core has
+  uploaded [binaries][bcc 0.17] for 0.17 Release Candidate (RC) 3.
+  Testing is greatly appreciated and can help ensure the quality of the
+  final release.
+
+## News
+
+- **BIP151 discussion:** as mentioned in [Newsletter #10][news10 news],
+  Jonas Schnelli has [proposed][schnelli bip151] an updated draft of
+  [BIP151][] encryption for the peer-to-peer network protocol.
+  Cryptographer Tim Ruffing provided [constructive criticism][ruffing
+  bip151] of the draft on the Bitcoin-Dev mailing list this week that
+  received also-constructive rebuttals from Schnelli and Gregory
+  Maxwell.  These posts may be interesting reads for anyone wondering
+  why certain cryptographic choices were made in the protocol, such as
+  the use of the NewHope quantum-computing resistant key exchange.
+
+- **W3C Web Payments Working Group update:** Lightning Network developer
+  Christian Decker is a member of this group attempting to create
+  standards for web-based payments.  In a [reply][decker w3c] sent to
+  the Lightning-Dev mailing list, Decker explains why he thinks the
+  current draft specification will be fundamentally compatible with both
+  payments to Bitcoin addresses and Lightning Network payments.  The
+  draft even explicitly allocates the XBT currency code to Bitcoin.
+
+## Notable commits
+
+*Notable commits this week in [Bitcoin Core][core commits], [LND][lnd
+commits], and [C-lightning][cl commits].  Reminder: new merges to
+Bitcoin Core are made to its master development branch and are unlikely
+to become part of the upcoming 0.17 release---you'll probably have to
+wait until version 0.18 in about six months from now.*

+
+- [Bitcoin Core #12775][] adds support for RapidCheck (a [QuickCheck][]
+  reimplementation) to Bitcoin Core, providing a property-based testing suite
+  that generates its own tests based on what programmers tell it are the
+  properties of a function (e.g. what it accepts as input and returns
+  as output).
+
+- [Bitcoin Core #12490][] removes the `signrawtransaction` RPC from the
+  master development branch.  This RPC is labeled as deprecated in the
+  upcoming 0.17 release and users are encouraged to use the
+  `signrawtransactionwithkey` RPC when they are providing their own
+  private key for signing or the `signrawtransactionwithwallet` RPC when
+  they want the built-in wallet to automatically provide the private key.
+
+- [Bitcoin Core #14096][] provides [documentation for output script
+  descriptors][] which are used in the new `scantxoutset` RPC in Bitcoin
+  Core 0.17 and are expected to be used for other interactions with the
+  wallet in the future.
+
+- LND made almost 30 merges in the past week, many of which made
+  small enhancements or bugfixes to its autopilot facility---its ability
+  to allow users to choose to automatically open new channels with
+  automatically-selected peers.  Several merges also updated which
+  versions of libraries LND depends upon.
+
+- C-Lightning added several hundred lines of documentation to its
+  repository this week, most of it inline code documentation or updates
+  to files in its [/doc directory][c-lightning docs].
