-FIXME:Gustavojfe
+- [Bitcoin Core #33908][] adds `btck_check_block_context_free` to the
+  `libbitcoinkernel` C API (see [Newsletter #380][news380 kernel]) for
+  validating candidate blocks with context-free checks: block size/weight
+  limits, coinbase rules, and per-transaction checks that do not depend on
+  chainstate, the block index, or the UTXO set. Callers can optionally enable
+  proof-of-work verification and merkle-root verification in this endpoint.
+
+- [Eclair #3283][] adds a `fee` field (in msats) to the full-format responses
+  of the `findroute`, `findroutetonode`, and `findroutebetweennodes` endpoints
+  used for pathfinding. This field provides the route's total
+  [forwarding fee][topic inbound forwarding fees], eliminating the need for
+  callers to compute it manually.
+
+- [LDK #4529][] enables operators to set different limits for announced and
+  [unannounced channels][topic unannounced channels] when configuring the total
+  value of inbound [HTLCs][topic htlc] in flight, as a percentage of channel
+  capacity. The defaults are now 25% for announced channels and 100% for
+  unannounced channels.
+
+- [LDK #4494][] updates its internal [RBF][topic rbf] logic to ensure compliance
+  with [BIP125][]'s replacement rules at low feerates. Instead of only applying
+  the 25/24 feerate multiplier specified in [BOLT2][], LDK now uses whichever is
+  larger: that multiplier or an additional 25 sat/kwu. A related specification
+  clarification is being discussed in [BOLTs #1327][].
+
+- [LND #10666][] adds a `DeleteForwardingHistory` RPC and an `lncli
+  deletefwdhistory` command, enabling operators to selectively delete forwarding
+  events older than a chosen cutoff timestamp. A minimum age guard of one hour
+  prevents the accidental removal of recent data. This feature enables routing
+  nodes to delete historical forwarding records without resetting the database
+  or taking the node offline.
+
+- [BIPs #2099][] publishes [BIP393][], which specifies an optional annotation
+  syntax for output script [descriptors][topic descriptors], enabling wallets to
+  store recovery hints, such as a birthday height to speed up wallet scanning
+  (including for [silent payment][topic silent payments] scanning). See [Newsletter
+  #394][news394 bip393] for initial coverage of this BIP with additional
+  details.
+
+- [BIPs #2118][] publishes [BIP440][] and [BIP441][] as Draft BIPs in the Great
+  Script Restoration (or Grand Script Renaissance) series (see [Newsletter #399][news399 bips]).
+  [BIP440][] proposes the Varops Budget for Script Runtime Constraint (see
+  [Newsletter #374][news374 varops]); [BIP441][] describes a new
+  [tapscript][topic tapscript] version that restores opcodes disabled in 2010
+  such as [OP_CAT][topic op_cat] (see [Newsletter #374][news374 tapscript]) and
+  limits script evaluation costs per the varops budget introduced in BIP440.
+
+- [BIPs #2134][] updates [BIP352][] ([silent payments][topic silent payments]) to
+  warn wallet developers not to let policy filtering, such as for
+  [dust][topic uneconomical outputs], affect whether scanning continues after a
+  match is found. Treating a filtered-out output as if there were no match can
+  cause the wallet to prematurely stop scanning and miss later outputs from the
+  same sender.
