Core: Stream attribute in both HttpRequest and HttpResponse to allow handling streaming objects and to get closer to
httpx interfaces.
Core/Http: Stream attribute in both HttpRequest and HttpResponse to allow handling streaming objects and to get
closer to httpx interfaces.
Core/Services: Services definitions are now using a declarative configuration format, that can be loaded by
applications. A sphinx extension was added to automatically document service definitions from applications.
Notifications: Implements a simple way to send notifications to a slack or a google chat webhook to catch errors.
Proxy: Added support for multiple remote urls for a given endpoint.
Proxy: Added support for default/fallback pools in remote configuration for resilience.
Proxy: Added a simple but functional circuit breaker implementation.
Proxy: Add probe implementation in background.
Proxy: Add liveness configuration support to proxy (in both remote endpoints and remote) to be able to select a
liveness check algorithm. For now, supported algorithms are "ignore" (do nothing), "naive" (old behaviour with simple
thresholds), "leaky" for a leaking bucket, and "inherit" (use parent algorithm). The default is "inherit", and if all
settings in config chain are set to "inherit", the top-level default is "naive".
Frontend: Generate typescript types from models, using the intermediary json schema generation provided by pydantic.
Storage: Added a new db:merge command to generate merge revisions from alembic.

Config: the settings are now implemented using pydantic, with more strictness so that settings only contains settings
and state-related things are moved to wrappers. The new harp.config.Configurable base class is now used for all
settings classes, and a new harp.config.Stateful allows to define settings wrappers for stateful objects.
Config: Redis configuration is now separated from blob storage, as it may be used by much more than just blobs.
Core: EVENT_CONTROLLER_VIEW event has been renamed to EVENT_CORE_VIEW for consistency with other event names.
Core/Http: Removed WrappedHttpRequest, inner HttpRequests can now be accessed directly.
Core/Http: HttpRequest can now be instanciated without an explicit implementation. If no implementation is provided,
then the kwargs data is passed to a stub implementation, allowing a simpler way to create requests (in tests, for
example).
DX: adds a harp examples list command to list available examples
DX/Helm: adds the ability to override environment in helm chart's values

Storage: added missing index on messages.transaction_id to speed up dashboard search queries.

Config: old settings classes have been removed (Definition, DisableableBaseSettings, DisabledSettings, Lazy, Settings)
along with related helper (settings_dataclass).
