 wallets and services.*
 
-FIXME:bitschmidty
+- **Wallet 10101 beta testing pooling funds between LN and DLCs:**
+  10101 announced a [wallet][10101 github] built with LDK and BDK that allows users to trade
+  derivatives non-custodially using [DLCs][topic dlc] in an [offchain contract][10101 blog2]
+  that can also be used to send, receive, and forward LN payments. The DLCs rely
+  on oracles that use [adaptor signatures][topic adaptor signatures] for price
+  [attestation][10101 blog1].
+
+- **LDK Node announced:**
+  The LDK team [announced][ldk blog] LDK Node [v0.1.0][LDK Node v0.1.0]. LDK Node is a
+  Lightning node Rust library that uses the LDK and BDK libraries to enable developers
+  to quickly setup a self-custodial Lightning node while still providing a high degree of
+  customization for different use cases.
+
+- **Payjoin SDK announced:**
+  [Payjoin Dev Kit (PDK)][PDK github] was [announced][PDK blog] as a Rust
+  library that implements [BIP78][] for use in wallets and services that wish to
+  integrate [payjoin][topic payjoin] functionality.
+
+- **Validating Lightning Signer (VLS) beta announced:**
+  VLS allows the separation of a Lightning node from the keys that control its
+  funds. A Lightning node running with VLS will route signing requests to a
+  remote signing device instead of local keys. The [beta release][VLS gitlab]
+  supports CLN and LDK, layer-1 and layer-2 validation rules, backup/recovery
+  capabilities, and provides a reference implementation. The [blog
+  post][VLS blog] announcement also calls for testing, feature requests, and feedback from the community.
+
+- **BitGo adds MuSig2 support:**
+  BitGo [announced][bitgo blog] support for [BIP327][] ([MuSig2][topic musig])
+  and noted the reduced fees and additional privacy compared to their other
+  supported address types.
+
+- **Peach adds RBF support:**
+  The [Peach Bitcoin][peach website] mobile application for peer-to-peer
+  exchange [announced][peach tweet] support for [Replace-By-Fee (RBF)][topic rbf] fee bumping.
+
+- **Phoenix wallet adds splicing support:**
+  ACINQ [announced][acinq blog] beta testing for the next version of their
+  Phoenix mobile Lightning wallet. The wallet supports a single dynamic channel
+  that is rebalanced using [splicing][topic splicing] and
+  a mechanism similar to the [swap-in-potentiam][news233 sip] technique (see
+  [Podcast #259][pod259 phoenix]).
+
+- **Mining Development Kit call for feedback:**
+  The team working on the Mining Development Kit (MDK) has [posted an update][MDK blog] on their
+  progress to develop hardware, software, and firmware for Bitcoin mining systems. The post
+  calls for feedback from the community about use cases, scope, and approach.
+
+- **Binance adds Lightning support:**
+  Binance [announced][binance blog] support for sending (withdrawals) and
+  receiving (deposits) using the Lightning Network.
+
+- **Nunchuk adds CPFP support:**
+  Nunchuk [announced][nunchuk blog] support for [Child-Pays-For-Parent
+  (CPFP)][topic cpfp] fee bumping for both senders and receivers of a transaction.
