The function is already provided in
contrib/pyln-testing/pyln/testing/utils.py (which is also
imported in this module), so there is no need to define it
a second time.
The variable `block` (instace of `struct block`) is
allocated on the stack without being initialized, i.e. its
member `prev` points to nowhere. This causes a segmentation
fault on my machine on the binding of "prev_hash" on running
`wallet_block_add`, as the following core-dump analysis
shows:
$ egdb ./wallet/test/run-wallet ./run-wallet.core
[...]
Core was generated by `run-wallet'.

This renames all occurences of use_proxy_always to always_use_proxy
to keep it inline with config values. This was a bit confusing.
Only significant change is that the payload in the plugins init
requests also contained the old name. No plugin currently seems to make
use of this variable yet. The old name 'use_proxy_always' is added when
deprecated APIs is enabled.
Changelog-Deprecated: Plugins: Renames plugin init 'use_proxy_always' to 'always_use_proxy'
This does two things:
- It moves non-tor addresses upfront so it prefers normal connection
which are less laggy and more reliable.
- It prevents connectd from trying the same wire_addr twice when the
addr_hint was given and gossip also added the same address.
Changelog-Changed: connectd: try non-TOR connections first
Changelog-Fixed: connectd: do not try address hint twice
We actually were waiting for l3 to disconnect, not l2.
But in general we should be looking for status rather than grovelling
in the logs where possible, so I changed all those.

We fail waiting for 'Resolved OUR_UNILATERAL/DELAYED_OUTPUT_TO_US by our proposal OUR_DELAYED_RETURN_TO_WALLET'
because we close *two* channels, but only wait for one transaction before mining a block.
This means we might only have one, and we immediately mine the next wait_for_mempool=1,
so the OUR_DELAYED_RETURN_TO_WALLET isn't mined.

If l3 is too slow, it can get channel_announcement after channel
is closed, so it gets upset at the node_announcement which follows:

This actually caused the flake in test_funding_reorg_private, where
l1 and l2 might not mark the original channel disabled. In fact, they
should *remove* it as it gets reorged out.

Return false if the timelock didn't mature yet, not the other way
around.
Also, the check shouldn't be strict: if the CSV is 1 it is valid
at utxo->blockheight + 1.

dualopend doesn't always listen to lightningd messages, so it would

It subsumes `decodepay`, and it's nicer if people can just assume it's
available at all times.

I spent an hour thinking this code had a bug (see test vector fix);
we *do* overallocate the tree, but that's deliberate: we fill with NULLs
and ignore on recursion.
The Merkle recurse comment had an out-by-one, and the NULL-pad
technique used was uncommented.

We were printing out the final merkle root before calculating it,
resulting in the final one being the same as the previous.

The issue is that the new keyword `force_lease_closed` was being set
even if the user didn't specify it, which results in breakage if this
new pyln version talks to older c-lightning nodes that don't have this
keyword yet. By setting the default to `None` it gets filtered out if
the user has not explicitly set it, but still retains the `True` /
`False` values if they did.
Changelog-None Issue is not present in released versions
Pointed out by @fiatjaf, and indeed it happened to me as well; a peer with
a high feerate reconnects and sends a similar (but now ludicrous) feerate,
and we get upset:
```
$ lightning-cli listpeers 039c73f53daad1050a6a72afb5353a2152f3152ee17168cd0ab28c2cb3e0050e36

Then in the logs:
