# Changes in 0.3.4:
* Remove needless heapless dependency left over from earlier iterations of the crate.
* Update README.
# Changes in 0.3.3:
* Add builder to Error: `with_title`
# Changes in 0.3.2:
* Add new constructors to Error:
`unauthorized`, `forbidden`
# Changes in 0.3.1
* Add new constructors to Error:
`not_acceptable`, `unsupported-content_format`, `from_unionerror`
* Fix insufficiently versioned dependency to coap-numbers
# Changes in 0.3.0
*This is a breaking change relative to alpha.1*
* OptionsExt:
Use return-position-impl-trait-in-trait, removing the `nontrivial_option_processing` feature.
This makes the return types unnamable until type-alias-impl-trait is stabilized.
* Moved the almost all of the crate that imlements coap-message into the new coap-message-implementations crate.
* Moved in types and traits of coap-handler-implementations
- the `Error` type, incompatibly replacing InternalServerError.
An `.internal_server_error()` constructor is added to make up for it.
- all option iteration related triaits and types: `OptionsExt`, `TryFromOption` and all block types
# Changes in 0.3.0-alpha.1
* Switched to coap-message 0.3.0-alpha.1 and its fallible writing;
this adds the WriteError type that expresses the cause.
* Introduced InternalServerError
* Intorduced a `reset()` method on the writable message as a stopgap measure
until rewindable message traits are available.
