Just a heads up, you linked to the Erlang 25.1 README instead of 26.1.

Great job to everyone involved with this release!

Speaking of releases,

% sudo apt update
…
Err:18 http://binaries.erlang-solutions.com/debian jammy Release
404 Not Found [IP: 13.33.21.93 80]
…
E: The repository ‘http://binaries.erlang-solutions.com/debian jammy Release’ does not have a Release file.

What do I do about this, especially to get an updated Erlang?

IIRC erlang-solutions stopped providing packages a while back (in Feb I think)

Using the RabbitMQ PPA for Erlang is an option if you just want pre-compiled debs vs building your own release with kerl/asdf

There’s been some work over there to support jammy, see https://github.com/esl/packages/issues/15 for the latest. I just use asdf these days.

What is the correct way of reusing ports with gen_udp in OTP26.1?

Previosly, we did gen_udp:open(Por, [{inet_backend, socket}, {reuseaddr, true}]) and I see reuseport was added in [erts, kernel] reuseaddr/reuseport/exclusiveaddruse support/fixes by rickard-green · Pull Request #6522 · erlang/otp · GitHub but I don’t get it to work:

1> gen_udp:open(88888, [{inet_backend, socket}, {reuseaddr, true}, {reuseport, true}]).
{ok,{'$inet',gen_udp_socket,
             {<0.92.0>,
              {'$socket',#Ref<0.1985961887.3750363144.125730>}}}}
2> gen_udp:open(88888, [{inet_backend, socket}, {reuseaddr, true}, {reuseport, true}]).
{error,eaddrinuse}

In OTP26.0.2:

1>  gen_udp:open(88888, [{inet_backend, socket}, {reuseaddr, true}]).
{ok,{'$inet',gen_udp_socket,
             {<0.26238807.0>,
              {'$socket',#Ref<0.3205098475.2836529154.55286>}}}}
2> gen_udp:open(88888, [{inet_backend, socket}, {reuseaddr, true}]).
{ok,{'$inet',gen_udp_socket,
             {<0.26238551.0>,
              {'$socket',#Ref<0.3205098475.2836529154.59029>}}}}
