### 2026-08-28: RNS 1.5.1
This release focuses on dataplane control, memory bounding and transport throughput, with adaptive ingress and egress control for interfaces, a new (and very efficient) zero-copy coalescing transmit buffer, an optimized HDLC deframer, and a range of other improvements to the inbound packet processing paths. It also introduces support for live profiling, and various new diagnostics output in `rnstatus`, along with a number of bug fixes and general improvements.
**Changes**
- Added adaptive dataplane egress control
- Added adaptive dataplane ingress control
- Added zero-copy coalescing transmit buffers to interfaces using the `BackboneInterface` backend
- Added early protocol violation checks for invalid frames
- Added transport implementation name and version to discovery information requirements
- Added full live profiling to the built-in `Profiler` primitive, by **K8**
- Added the `@RNS.Profiler.profile` decorator, by **K8**
- Added support for indefinitely running, reentrant profilers with bounded capture, by **K8**
- Added live profiling results output to `rnstatus`, by **K8**
- Added PPS statistics to `rnstatus`
- Added interface MTU display to `rnstatus`
- Added interface TX drop statistics to `rnstatus`
- Added interface TX buffer size output to `rnstatus`
- Added throughput benchmarker to the test suite
- Added support for natively compiled module builds, and the ability to load compiled modules when available
- Added module compilation status reporting from in-wheel build information
- Added parity tests for HDLC, IFAC and HKDF against the legacy implementations
- Added shared medium hints to interfaces
- Improved memory and CPU consumption under high traffic loads
- Improved traffic class handling
- Optimized HKDF to ~5.7x performance, if this worries you, **good**; then see the full parity and standard vector test suite and read the code
- Optimized inbound and outbound IFAC handling to ~90x performance on large frames
- Optimized inbound packet processing by reducing lock acquisitions and path table contention
- Optimized lookups for pending and active links using hash maps for lookup operations
- Optimized announce validation by caching signature validation results, significantly lowering announce storm CPU load
- Optimized the HDLC deframer
- Reduced redundant packet hashing in inbound processing
- Tuned default inbound queue lengths and announce queuing
- Tuned automatic interface MTU configuration
- Fixed `Resource` transfers failing when initialized from stream-based data sources that fell outside `MAX_EFFICIENT_SIZE`
- Fixed an invalid prefix stripping bug in the `rngit` page server (`.something` files not viewable)
- Fixed RSSI/SNR reporting regression
- Fixed keepalive handling on non-epoll backends
- Fixed a bug in `rngit` page navigation content initialization order
- Fixed the `rngit` page node not being able to serve in-tree downloads for large files
- Fixed `rnstatus` blocked IP listing including IPs that were actually not yet blocked
- Fixed `rnstatus` traffic totals counting the local shared instance inter-app transit in totals
- Fixed various minor bugs in `rnsh`, `rnir`, identity handling
- Fixed a latent bug in the AES module, where an exception would not resolve it's exception description correctly, and instead raise another exception.
- Removed dead Python 2 code from `umsgpack`
**Verified Retrieval**
You can retrieve and verify this release over Reticulum using the built-in `rngit release` utility. To retrieve only the installation `.whl` package, and the release manifest for future updates, you can use:
```sh
rngit release rns://7649a50d84610232d1416b41d2896aff/reticulum/reticulum fetch "latest:rns-*.whl" --signer bc7291552be7a58f361522990465165c
```
To download all artifacts, including the documentation and source archive, you can use the following command:
```sh
rngit release rns://7649a50d84610232d1416b41d2896aff/reticulum/reticulum fetch latest:all --signer bc7291552be7a58f361522990465165c
```
**Release Signatures**
Release artifacts include a signed `rsm` release manifest and `rsg` signature files that can be validated against the RNS release signing identity `<bc7291552be7a58f361522990465165c>` using `rngit` or `rnid`. To perform an offline verification of all release artifacts using a manifest:
```sh
rngit release rns_*.rsm verify --signer bc7291552be7a58f361522990465165c
```
To verify release artifacts using individual `rsg` files, while also verifying the manifest itself, download the `rsm` and `rsg` signatures, make sure they are in the same folder as the release artifact, and run `rnid` signature verification with the release identity as the required signer:
```sh
rnid -i bc7291552be7a58f361522990465165c -V rns_*.rsm *.rsg
```
The `rnid` utility will then verify the signatures, and display whether they are valid. If the signature cannot be verified, the release has been tampered with and should be discarded.
