new 7d58968236ea Removal of camel-headersmap
7d58968236ea is described below
commit 7d58968236ea4a39dd6ebc7ced638ba45ed5ab31
Author: Aurélien Pupier <[email protected]>
AuthorDate: Wed Aug 26 14:22:35 2026 +0200
Removal of camel-headersmap
The component camel-headersmap was deprecated in 4.21. The default
`CaseInsensitiveMap` in camel-core
uses a custom O(1) hash table with zero-allocation lookups and header
key deduplication, making the external
cedarsoftware `java-util` dependency unnecessary. Simply remove the
`camel-headersmap` dependency from your
project — the core implementation now provides equivalent or better
performance.

=== Components removal
+==== camel-headersmap
+
+The component camel-headersmap was deprecated in 4.21. The default
`CaseInsensitiveMap` in camel-core
+uses a custom O(1) hash table with zero-allocation lookups and header key
deduplication, making the external
+cedarsoftware `java-util` dependency unnecessary. Simply remove the
`camel-headersmap` dependency from your
+project — the core implementation now provides equivalent or better
performance.
+
==== camel-iec60870
`camel-iec60870` was deprecated in 4.21. The library used to implement it
NeoScada is no more maintained since
