Changed

• [breaking] Python lib signatures have changed (Miniconf.create(), discover())
• Python lib discovery timeout has been optimized to work well for both slow
  connections (high RTT) and fast ones
• [breaking] The MQTT client does not own the miniconf settings struct anymore.
• [breaking] handled_update() has been removed from the MQTT client in favor of validator/getter/setter callbacks.
• [breaking] The MQTT client has been split into its own miniconf_mqtt crate.
• [breaking] The attribute syntax has changed from #[tree(depth(1))] to #[tree(depth=1)].
• [breaking] The default depth is 0, also in the case where a #[tree()] without depth has been specified.
• [breaking] The traverse_by_key callback also receives the number of indices at the given level.
• The trait methods are now generic over Keys and not over Iterator<Item: Key>.
  A blanket implementation has been provided.
• JsonCoreSlash::{set,get}_json_by_indices() removed in favor of {get,set}_json_by_key().
• [breaking] Error::PostDeserialization renamed to Error::Finalization.
• [breaking] json-core removed from default features.
• [breaking] Bumped MSRV to 1.70.0

Full Changelog: v0.9.0...v0.10.0

Full Changelog: v0.10.0...miniconf-v0.10.1

Changed

• The Miniconf trait has been split into TreeKey for the keys/path/indices and traversal,
  the TreeSerialize for serialization, and TreeDeserialize for deserialization.
  The derive macros have been split accordingly. A shorthand #[derive(Tree)] macro has been
  added to derive all three traits. The struct field attribute controlling
  recursion depth has been renamed to #[tree(depth(Y))].
• [mqtt] The List command of the MqttClient now has a maximum correlation data length of 32 bytes
• [mqtt] The MqttClient API has changed to support new Minimq versions
• [mqtt] The Get command now only generates a single message in response to the provided
  ResponseTopic instead of a response type (with success) and a message on the original topic.
• [mqtt] Handler function singatures now require Display instead of AsRef<str> types

Added

• Deserializing with borrowed data is now supported.
• [derive] Added #[tree(skip)] macro attribute to allow skipping entries.

Added

• Traversal by names or indices has been added through Miniconf::traverse_by_key().
• The Miniconf derive macro supports (unnamed) tuple structs.

Removed

• [breaking] The Array and Option newtypes have been removed. Instead in structs
  the desired Miniconf<N> recursion depth for a field is indicated by an attribute
  #[miniconf(defer(N))] where N is a usize literal. The depth is communicated
  via the trait. For [T;N] and Option the depth up to 8 has been implemented.
  For structs it is arbitrary.

Changed

• [breaking] The Miniconf trait is now generic over the Deserializer/Serializer. It
  doesn't enforce serde-json-core or u8 buffers or / as the path hierarchy
  separator anymore.
• [breaking] Miniconf::iter_paths() takes the path hierarchy separator and passes
  it on to Miniconf::path() and Metadata::separator().
• [breaking] The Miniconf trait has been stripped of the provided functions that depended
  on the serde-backend and path hierarchy separator. Those have been
  moved into the JsonCoreSlash trait that has been implemented for all Miniconf
  to provide the previously existing functionality.
• [breaking] set() and get() have been renamed to set_json() and get_json()
  respectively to avoid overlap.
• [breaking] Paths now start with the path separator (unless they are empty).
  This affects the Miniconf derive macro and the Miniconf implementation pairs
  for Option/Array.
  Downstram crates should ensure non-empty paths start with the separator and
  expect next_path paths to start with the separator or be empty.
• The main serialization/deserialization methods are now Miniconf::{set,get}_by_key()
  They are generic over the key iterator Iterator<Item: miniconf::Key>.
• The only required change for most direct downstream users the Miniconf trait
  to adapt to the above is to make sure the JsonCoreSlash trait is in scope
  (use miniconf::JsonCoreSlash) and to rename {set,get}() -> {set,get}_json().
  The MqttClient has seen no externally visible changes.
• [breaking] iter_paths() and iter_paths_unchecked() now don't need the state
  size anymore as it's computed exactly at compile time.
• [breaking] iter_paths/PathIter is now generic over the type
  to write the path into. Downstream crates should replace iter_paths::<L, TS>() with
  e.g. iter_paths::<heapless::String<TS>>().
• [breaking] Re-exports of heapless and serde-json-core have been removed as they
  are not needed to work with the public API and would be a semver hazard.
• [breaking] Metadata is now computed by default without taking into account
  path separators. These can be included using Metadata::separator().
