Official project updates
This is a security/bug fix release for v1.22.2.
Fixes
- Emit warnings rather than error out when stripping executables fails on the firmware image packing step. These can happen when using precompiled Rust executables. They still work. The more important architecture checks are not impacted by this change.

System updates
This is a bug fix and Erlang version bump from 25.2 to 25.2.3. It should be a low risk upgrade.
Fixes
- Set Erlang crash dump timer to 5 seconds, so if an Erlang crash dump does happen, it will run for at most 5 seconds. See erlinit.conf.

RustlerPrecompiled and Rust NIF cross-compilation
Frank shared some cool stuff being done with Explorer by the Nx project to make their Rust NIFs work better for embedded use. See post on Mastodon.

Supporting the Nerves project
We want to encourage everyone to contribute in whatever way works for them. Here are some ways we currently recommend:
- Write or port a new hardware library and include it in the Elixir Circuits collection.
- Give money to the project via Open Collective.
- Get in touch about taking over maintenance duties for some libraries, we might be able to provide you hardware.
- Apply for an EEF stipend on something Nerves-related and build it. We can help if you have questions about this.
- Send corrections or improvements for documentation wherever it fails to help you.
- Write about Nerves, give talks about Nerves. Make videos about Nerves. It is all good.
Finally, if you have questions about the newsletter or want to suggest something you can simply respond to this email it will go directly to me, Lars, who edits this thing. Let me know what you think.
