The `camel-olingo2` and `camel-olingo4` component are deprecated.
This is due the Apache Olingo project is EOL and has been moved to the attic and is no longer maintained.

=== camel-vertx-websocket

The `vertx-websocket` consumer now applies a `HeaderFilterStrategy` to the WebSocket query and
path parameters before mapping them into the Camel message headers. The new default
`VertxWebsocketHeaderFilterStrategy` filters headers starting with `Camel` / `camel`
(case-insensitive) in both the inbound and outbound directions, aligning the component with the
rest of the Camel component catalog (`camel-coap`, `camel-kafka`, `camel-nats`, ...). A new
`headerFilterStrategy` endpoint option is available; routes that relied on receiving
`Camel`-prefixed header names from WebSocket query or path parameters can supply a custom
`headerFilterStrategy` to restore the previous behaviour.

=== camel-atmosphere-websocket

The `atmosphere-websocket` consumer now applies the endpoint `HeaderFilterStrategy` to the
WebSocket query parameters before mapping them into the Camel message headers. The inherited
default `HttpHeaderFilterStrategy` filters headers starting with `Camel` / `camel`
(case-insensitive). Routes that relied on receiving `Camel`-prefixed header names from WebSocket
query parameters can supply a custom `headerFilterStrategy` to restore the previous behaviour.

=== camel-iggy

The `iggy` consumer now applies a `HeaderFilterStrategy` to the Iggy message user-headers before
mapping them into the Camel message headers. The new default `IggyHeaderFilterStrategy` filters
headers starting with `Camel` / `camel` (case-insensitive) in both the inbound and outbound
directions, aligning the component with the rest of the Camel component catalog. A new
`headerFilterStrategy` endpoint option is available; routes that relied on receiving
`Camel`-prefixed user-header names from Iggy messages can supply a custom `headerFilterStrategy`
to restore the previous behaviour.
