# Release Notes
## Routing
* The default CLTV delta delay [has been increased from 40 blocks to 80
blocks](https://github.com/lightningnetwork/lnd/pull/7609).
## Wallet
- The logging around transaction broadcast failures [has been improved by always
logging the causing error and the raw transaction as
hex](https://github.com/lightningnetwork/lnd/pull/7513).
## `lncli`
* The `lncli wallet psbt fund` command now allows users to specify the
[`--min_confs` flag](https://github.com/lightningnetwork/lnd/pull/7510).
* [Add time_lock_delta overflow check for UpdateChannelPolicy](https://github.com/lightningnetwork/lnd/pull/7350)
that ensure `time_lock_delta` is greater or equal than `0` and less or equal than `65535`
* [Added ability to backup, verify and
restore single channels](https://github.com/lightningnetwork/lnd/pull/7437)
to and from a file on disk.
* [Add a `fundmax` flag to `openchannel` to allow for the allocation of all
funds in a wallet](https://github.com/lightningnetwork/lnd/pull/6903) towards
a new channel opening.
## Watchtowers
* [Fix Address iterator
panic](https://github.com/lightningnetwork/lnd/pull/7556)
* [Allow caller to filter sessions at the time of reading them from
disk](https://github.com/lightningnetwork/lnd/pull/7059)
* [Clean up sessions once all channels for which they have updates for are
closed. Also start sending the `DeleteSession` message to the
tower.](https://github.com/lightningnetwork/lnd/pull/7069)
* [Don't load exhausted sessions when not
needed](https://github.com/lightningnetwork/lnd/pull/7405). Also add a new
`exclude_exhausted_sessions` boolean flag to the relevant lncli wtclient
commands.
* [Recover from StateUpdateCodeClientBehind
error](https://github.com/lightningnetwork/lnd/pull/7541) after data loss.
## Build
* [ldflags were being incorrectly passed](
https://github.com/lightningnetwork/lnd/pull/7359)
## Misc
* [Return `FEE_INSUFFICIENT` before checking balance for incoming low-fee
HTLCs.](https://github.com/lightningnetwork/lnd/pull/7490).
* Optimize script allocation size in order to save
[memory](https://github.com/lightningnetwork/lnd/pull/7464).
* When resolving outgoing HTLCs onchain, the HTLC timeout resolver will now
[monitor mempool](https://github.com/lightningnetwork/lnd/pull/7564) for
faster preimage extraction.
## Spec
* [Add test vectors for
option_zero_fee_htlc_tx](https://github.com/lightningnetwork/lnd/pull/7439)
## RPC
* A [debug log](https://github.com/lightningnetwork/lnd/pull/7514) has been
added to `lnrpc` so the node operator can know whether a certain request has
happened or not.
* [Add peer_scid_alias to the response of
`listchannels`](https://github.com/lightningnetwork/lnd/pull/7366)
* Message `funding_locked` [has been
renamed](https://github.com/lightningnetwork/lnd/pull/7517) to
`channel_ready` internally to match the specs update. This should not change
anything for the users since the message type(36) stays unchanged, except in
the logging all the appearance of `funding_locked` replated expression is
replaced with `channel_ready`.
## Bug Fixes
* [Fix a bug where lnd crashes when psbt data is not fully
available](https://github.com/lightningnetwork/lnd/pull/7529).
* [Put back P2TR as default change type
in batch_open_channel](https://github.com/lightningnetwork/lnd/pull/7603).
* [Fix log output](https://github.com/lightningnetwork/lnd/pull/7604).
* [Channels opened with custom fee policies are now able to forward payments
correctly without needing to restart
first](https://github.com/lightningnetwork/lnd/pull/7597).
* [Fix a bug](https://github.com/lightningnetwork/lnd/pull/7613) where the
funding manager would error out if no persisted initial forwarding policy is
found for a channel.
* The internal rebroacaster [will no longer continue to rebroadcast stale
sweeper transactions (have a conflict mined or in the
mempool)](https://github.com/lightningnetwork/lnd/pull/7599).
