npm module grpc is deprecated as of April 2021.
The recommended replacement is @grpc/grpc-js.
The replacement is compatible with the use cases presented in JS examples and so switching examples to it requires only changes to the list of npm modules to install and the imports.

Improve 'ErrReservedValueInvalidated' error string to explain that the
error is triggered by a transaction that would deplete funds reserved for
potential future anchor channel closings (via CPFP)
Add hint that further details can be found in the debug log
Update strings in 'lntest/itest/log_error_whitelist.txt' correspondingly
Since we don't really do anything with the errors we check in the itest
error whitelist but get a lot of failed Travis runs because of it, we
disable the check for the moment.
To avoid a naming conflict with etcd, we rename our very generic
rpc.proto to lightning.proto to match the service name that's declared
within. This will break many external tutorials and possibly also our
API docs but the change needs to be done eventually.
This removes a warning in the documentation saying that pruned nodes are
not supported. This is no longer the case as [pruning is supported since
0.13](https://github.com/lightningnetwork/lnd/pull/5154). So instead it
now says pruning is supported and notes the version and implications of
pruning.
This changes file reation mode on admin macaroon from 0600 to 0640. The
reason is to make permission management easier.
Closes#4385
**Is this safe?**
Yes, it is. Assuming a reasonably secure Linux system, it will have a
separate group for each user. E.g. a new user `lnd` gets assigned group
`lnd` which nothing else belongs to. A system that does not do this is
inherently broken already.
Since there is no other user in the group, no other user can read admin
macaroon unless the administrator explicitly allowed it. Thus there's no
harm allowing group read.
