+ Security bulletin
+
+
+ The release note below contain a CVE for NervesHub. So you don't miss it:
+
+
+
+ Recommend reading the release notes as it should not have any effect on most on-prem installs. But the update has a lot going for it regardless.
+
+
+ NervesConf EU wants you
+
+
+ If you have things of at least mild interest to share,
+
+ submit to the CFT
+
+ . People always underestimate how interesting their work is. We know there are a lot of you out there using Nerves that we've never talked to. We hope you come join us at NervesConf EU and Goatmire Elixir.
+
+
+ We are also looking for workshops as part of the CFT. You can look at some of the
+
+ currently available workshops
+
+ to get an idea of what that entails.
+
+
+ And for our US folks. To my knowledge there won't be a NervesConf US this year. So this is the only NervesConf you should expect. The Gig City Elixir organizers have told me they won't be running it this year and the people organizing NervesConf US have moved on to other things. I'd be interested in helping make it happen, another year, under better circumstances. Reach out if that's something you'd like to enable.

+
+ Nerves Workshop in Malaga
+
+
+ We like to connect with the community leading up to the major conferences. So we teamed up with the EEF to do an Elixir Unconference and a Nerves Workshop/Hack session in Malaga.
+
+
+ Please
+
+ read more and sign up
+
+ if you'll be there.
+
+
+ Website updates!
+
+
+ I was doing some cleanup on the website and realized it had some very outdated ideas of what videos and
+articles are available.
+
+
+ The
+
+ video archive
+
+ is now reasonably filled out. The
+
+ articles section
+
+ now has more fun stuff in it. There used to be 2 articles. And
+
+ the Newsletter archive
+
+ should now be indexed better by Google et.al. Hope that's helpful to you all.
+
+
+ For videos and articles, please send PRs if you are missing cool stuff in there.

+ Nerves Meetup EU
+
+
+ Paulo Valente, main maintainer of Nx and general numeric mastermind is bringing us a presentation on his embedded-friendly Nx backend based on the Eigen C++ library and more.
+
+
+ I've had the pleasure of running it on a client device as part of experimentation with acceleration. It ain't slow :)
+
+
+ There will also be social time with breakout rooms and the Meetup is turning into one of my favorite things of the month. A quick shot of community and people always share cool things.

+ nerves, v1.13.2
+
+
+
+ This release starts a process of modernizing the Nerves tooling. Most updates are behind the scenes so the plan is to roll them out incrementally to minimize the changes per release. This release focused on internal updates to HTTP request handling.
+
+
+ -
+ Changes
+
+ -
+ Turn off artifact download progress for non-interactive terminals
+
+ -
+ Show the .local hostname
+with nerves.discover rather than just the hostname. This makes it better for copy/paste use.
+
+ -
+ Download artifacts to disk rather than buffering entire contents before writing. This helps memory usage especially for large artifacts.

+
+ -
+ Update Nerves systems to 2.0.1 versions. See Nerves systems for details, but the main update is that the demo now uses the Raspberry Pi tryboot feature so that early boot issues (like Linux kernel and Erlang boot script crashes) revert to previous good firmware rather than
+cycling.

+
+
+
+
+ nerves_bootstrap, v1.15.1
+
+
+
+ This release doesn’t change any functionality. It contains internal changes to break a cyclic dependency
+with the :nerves package and help the maintainers.
+
+
+ This continues the prep work for bigger future Nerves tooling updates.
+
+
+ -
+ Changes
+
+ -
+ Check for Nerves Bootstrap updates first (once a day) to avoid running the check after loadpaths removed bootstrap from code paths. This fixes a potential update failure.
+
+ -
+ Move private bootstrap API to the NervesBootstrap package. The one call that’s used by older versions of Nerves is still available, but maintained
+separately. I.e., nothing should break.
+
+ -
+ Added many unit and integration tests
+
+
+
+
+
+
+ whenwhere, v0.3.0
+
+
+
+ This release adds a Cloudflare Workers implementation. It works almost identically with the main exception being that the TCP port number of the request isn’t returned in the address field.
+
+
+ -
+ Changes
+
+ -
+ Clarified nonce field max length to be 31 characters rather than 32 since that’s what’s deployed
+
+ -
+ Added REUSE compliance
+
+
+
+
+
+
+ This release comes with the discovery of CVE-2026-28806 (
+
+ read advisory
+
+ ). During routine development we noticed lacking authorization checks for device bulk actions. Investigating it we found that it did allow a user to take actions on devices outside of their organization by manipulating the client-side of the application. As part of this we also discovered an API endpoint that exposed an equivalent privilege escalation and ability to escape the scope.
+
+
+ If you run NervesHub for only your organization this issue may not affect you at all or would likely have low impact. It is privilege escalation and a tenancy violation. This is significantly more important to a multi-organization system such as NervesCloud. You should still update immediately since this may give unintended access to people in your organization.
+
+
+ The bulk action issue goes back to 2021 and is present in NervesHub 1.x as far back as bulk actions have existed. The API issue is more recent during a rework of the API endpoints. Details are in the CVE references.
+
+
+ Of course this has made us look very carefully at the structure of authorization and access in NervesHub. What we found was a lack of structure which increases the risk of
+introducing issues like this. In preparation for the CVE fixes we introduced a scoping mechanism to have a consistent way of passing around authorization scopes. This makes it more obvious when authorization is being checked and reduces the risk of introducing new issues. We have branches and PRs in the wings for enforcing authorization checks in LiveViews and API endpoints. Those should land shortly as well.
+
+
+ We take security very seriously. Finding a serious problem is never fun. Not finding it is significantly worse. This was discovered by us, fixed by us and released by us. We are thankful to the Erlang Ecosystem Foundation’s CNA for their great help in the CVE process. If you discover flaws in your Elixir project we highly encourage you to learn the correct process and the EEF CNA will help you through it.

+
+ AtomVM release.
+
+
+ I usually edit massive changelogs but AtomVM doesn't release very often so let's enjoy it :)
+
+
+
+ bb_servo_robotis, v0.2.2

+
+
+
+ bb_servo_feetech, v0.2.2
+
+
+
+
+
+
+
+ AtomVM, v0.7.0-alpha.0
+
+
+
+
+ This is an alpha release
+
+ , the first pre-release on the road to v0.7.0. It represents over two year of development and introduces several groundbreaking features. While we have taken care to test thoroughly, APIs may still evolve before the stable release. If you need maximum stability for production deployments, we recommend staying on
+
+ v0.6.x
+
+ . That said, we encourage you to try v0.7.0-alpha.0 and
+
+ report any issues
+
+ you encounter, your feedback is invaluable in shaping the stable release.
+
+
+
+ OTP-28 and OTP-29 are now supported.
+
+ This is a major improvement over v0.6.6 which did not include OTP-28 support. On macOS,
+
+ Homebrew
+
+ and
+
+ MacPorts
+
+ default to OTP-28 or later, so this
+release works out of the box with default system installations. You can use
+
+ asdf
+
+ or
+
+ mise
+
+ to manage multiple Erlang/OTP versions if needed.
+
+
+ Please read
+
+ the getting started guide
+
+ for flashing instructions.
+
+
+ Highlights
+
+
+ Distributed Erlang
+
+
+ AtomVM now supports the Erlang distribution protocol, allowing AtomVM nodes running on microcontrollers to connect to standard BEAM nodes or other AtomVM instances via message passing. This release includes:
+
+
+ -
+ A pure Erlang erl_epmd client implementation
+
+ -
+ Support for external pids, ports, and refs in external terms
+
+ -
+ Remote shell support (with the
+necessary io and io_lib functions)
+
+ -
+ Cookie-based authentication
+
+ -
+ The distribution protocol supports alternative transport carriers beyond TCP/IP, opening up communication paths specific to embedded systems
+
+
+
+ This enables powerful use cases: debugging an MCU directly from a standard OTP shell, coordinating multiple microcontrollers via message passing, and building mixed clusters of BEAM and AtomVM nodes. TLS distribution is not yet available.
+
+
+ JIT Compilation and Multiple Execution Modes
+
+
+ AtomVM now supports four execution strategies:
+
+
+ -
+
+ Emulated
+
+ - interprets BEAM bytecode (default, small and portable)
+
+ -
+
+ JIT
+
+ - runtime compilation to native code
+
+ -
+
+ Native (AoT)
+
+ - pre-compiled native code deployment
+
+ -
+
+ Hybrid
+
+ - native code with bytecode fallback for unsupported opcodes
+
+
+
+ The JIT compiler is itself written in Erlang. Supported JIT architectures include RISC-V32, ARM v6-M (Cortex-M0+), x86_64, and aarch64.
+
+
+ Big Integer Support
+
+
+ AtomVM now supports integers up to 256-bit (sign + 256-bit magnitude). All arithmetic operations (+, -, *, div, rem, abs, etc.) and all bitwise operations (band, bor, bxor, bnot, bsl, bsr) work with big integers. Serialization via binary_to_term/1 and term_to_binary/1,2 is also supported.
+
+
+ Cryptographic Operations
+
+
+ A comprehensive crypto module has been added:
+
+
+ -
+ Key generation and exchange (crypto:generate_key/2, crypto:compute_key/4)
+
+ -
+ Digital signatures
+(crypto:sign/4, crypto:verify/5)
+
+ -
+ Streaming hashes and MACs (crypto:hash_init/update/final, crypto:mac_init/update/final)
+
+ -
+ AEAD encryption (crypto:crypto_one_time_aead)
+
+ -
+ PBKDF2 key derivation (crypto:pbkdf2_hmac/5)
+
+ -
+ Ed25519 support via optional libsodium integration (AVM_USE_LIBSODIUM=ON)
+
+
+
+ ETS
+
+
+ A limited but functional implementation of the OTP ets interface is now available, including support for set, bag, and duplicate_bag table types with operations such
+as insert, lookup, delete, member, update_counter, update_element, and more.
+
+
+ Expanded Hardware Support
+
+
+ -
+
+ ESP32C5 and ESP32C61
+
+ : initial support for these new Espressif chips
+
+ -
+
+ ESP32P4 WiFi
+
+ : WiFi connectivity via esp-wifi-external (requires ESP-IDF v5.4+)
+
+ -
+
+ 10 new STM32 families
+
+ : enabled by switching to the official ST HAL/LL SDK
+
+ -
+
+ ESP-IDF v5.5
+
+ : release images are now built with ESP-IDF v5.5
+
+
+
+ Elixir Improvements
+
+
+ -
+ Native GenServer and Supervisor support
+
+ -
+ Added Function.ex and Protocol.ex for improved Elixir 1.18 support
+
+ -
+ Process.link/1 and Process.unlink/1
+
+ -
+ Base64 encode/decode functions in the Base module
+
+ -
+ ESP32 builds can now enable Elixir support with a simple cmake flag: -DATOMVM_ELIXIR_SUPPORT=on
+
+
+
+ WebAssembly
+
+
+ AtomVM’s Emscripten/WASM port continues to improve. Pre-built binaries are available for both Node.js and browser environments. This release powers projects like Popcorn, which runs Elixir directly in the browser, including the Elixir Language Tour.
+
+
+ POSIX File and Directory Operations
+
+
+ New POSIX functions for file I/O (seek, pread, pwrite, fsync, ftruncate, rename, stat, fstat) and directory operations (mkdir, rmdir) are now available on supported platforms.
+
+
+ Upgrade Notes
+
+
+ If upgrading from v0.6.x,
+please review the
+
+ UPDATING.md
+
+ file. Key changes:
+
+
+ -
+
+ Entry point change
+
+ : init:boot/1 is now used as the entry point if it exists. It automatically starts the kernel application and calls start/0 from the identified startup module. Users who were manually starting the kernel application (typically for distribution) must stop doing so. Starting net_kernel is still required.
+
+ -
+
+ Ports replace pids for native processes
+
+ : Port
+drivers should now return ports instead of pids. Socket matching code may need to change from is_pid/1 to is_port/1.
+
+ -
+
+ bsl overflow checking
+
+ : Bitshift left now checks for overflows. Mask values before shifting: e.g. (Value band 0xF) bsl 252.
+
+ -
+
+ binary_to_integer/list_to_integer
+
+ : No longer raise overflow: they raise badarg when the result exceeds 256 bits.
+
+ -
+
+ ESP32 Elixir builds
+
+ : Can now be configured with idf.py -DATOMVM_ELIXIR_SUPPORT=on set-target ${CHIP} instead of copying partition files.
+
+ -
+
+ C API
+
+ : The externalterm module
+has been renamed to external_term with a completely new API.
+
+ -
+
+ Removed
+
+ : The deprecated network_fsm module has been removed.
+
+
+
+ Pre-built Binaries
+
