RNS β 0.9.6

This release activates AES-256 as the default encryption mode for all communication. It is the last release that will support the old AES-128 based modes, which will be entirely phased out in the next release.

This release also includes a number of API and resource consumption improvements, and fixes a bug.

**Changes**
- Enabled AES-256 as default encryption mode for all traffic
- Added dynamic link keepalive and timeout calculation
- Added ability to efficiently transfer files as responses in the `Request` API
- Added ability to include metadata on `Resource` transfers
- Added option to specify `Resource` auto-compression limits
- Added option to specify `Request` response auto-compression limits
- Added `Resource` transfer example
- Added allow overwrite option to `rncp`
- Improved hardware MTU auto-configuration
- Improved handling of file transfers using the `Resource` API
- Improved `Resource` transfer memory consumption
- Improved memory consumption of applications connected to a shared instance
- Improved `rncp` memory consumption for large files
- Fixed announce handlers not triggering after shared instance disappearance

RNS β 0.9.5

This release initiates migration of Reticulum from AES-128 to AES-256 as the default link and packet cipher mode. It is a compatibility/migration release, that while supporting AES-256 doesn't use it by default. It will work with both the old AES-128 based modes, and the new AES-256 based modes. There's a very slight penalty in performance to support both the old and new modes at the same time, but only for single packet APIs (not links), and it really shouldn't be noticeable in any everyday use.

In the next release, version `0.9.6`, Reticulum will transition fully to AES-256 and use it by default for all communications. That means that both single packets and links will use AES-256 by default. The old AES-128 link mode may or may not be available for a few releases, but will ultimately be phased out entirely.

The update requires no intervention, configuration changes or anything similar from a users or developers perspective. Everything should simply work. This goes both for the 0.9.5 update, and the next 0.9.6 update that transitions fully to AES-256.

**Changes**
- Added support for AES-256 mode to links and packets
- Added dynamic link mode support
- Added temporary backwards compatibility for AES-128 link and packet modes
- Added `get_mode()` method to link API
- Added tests for all enabled link modes
- Added `instance_name` option and description to default config file
- Improved ratchet persist reliability if Reticulum is force killed while persisting ratchets
- Fixed interface string representation for some interfaces
- Fixed instance name config option being overwritten if option was not last in section
- Fixed unhandled potential exception on fast-flapping `BackboneInterface` connections

RNS β 0.9.0

This release lays the groundwork for future performance and resource utilisation optimisations. Most importantly, this release adds **link MTU autodiscovery**, which allow established links to use much higher MTUs than the base MTU of 500 bytes.

**Please note!** To actually use link MTU discovery, all transport nodes along the path must be upgraded to at least version `0.9.0`. Since this is the first release to add support for this feature, *it is currently **not** activated by default*, and no clients or applications will use it yet. Using link MTU autodiscovery by default will be enabled by default in RNS version `0.9.1`. Please upgrade your nodes!

Additionally, this release adds several new features, performance improvements and bug fixes, as well as support for RNodes running firmware version `1.81`.

**Changes**
- Added MTU autoconfiguration on interfaces that support higher MTUs
- Added link MTU autodiscovery and path clamping
- Added dynamic SDU calculations based on link MTU to `Resource`, `Channel` and `Buffer`
- Added resource EIFR continuity to split resource handling
- Added interference status to `RNodeInterface`
- Fixed a display bug in `rnstatus`
- Added live traffic stats to `rnstatus`
- Added T3S3 support to `rnodeconf`
- Added Heltec T114 support to `rnodeconf`
- Added LilyGO T-Echo support to `rnodeconf`
- Added option to print device configuration to `rnodeconf`
