This upgrade of io.micrometer:micrometer-core from version 1.1.5 to 1.16.3 introduces several significant changes and deprecations that require developer attention.

Key Breaking Changes:

• API Renaming (v1.10): The io.micrometer.common.Tags and io.micrometer.common.Tag classes have been renamed to io.micrometer.common.KeyValues and io.micrometer.common.KeyValue respectively. This will require updating imports and class references in your code.
• JDK HttpClient Instrumentation (v1.13): The JDK HttpClient instrumentation has been moved from micrometer-core to a new micrometer-java11 module. If you are using this instrumentation, you will need to add a new dependency and update your import paths. The classes in micrometer-core were deprecated and scheduled for removal in version 1.15.0.
• Prometheus Registry Changes (v1.13 & v1.16): The micrometer-registry-prometheus module was upgraded to use the Prometheus Java client 1.x, which resulted in breaking changes. The base package was changed from io.micrometer.prometheus to io.micrometer.prometheusmetrics. Additionally, in version 1.16, the sanitization of the colon character (:) in meter and tag names was changed; it is no longer replaced by an underscore (_).
• Removed Annotations: Deprecated io.micrometer.core.lang annotations have been removed.

Recommendation:
Developers should carefully review their use of Micrometer APIs, especially concerning Tags, KeyValues, and any direct interactions with the Prometheus registry or JDK HttpClient instrumentation. Code modifications will be necessary to adapt to these changes. It is recommended to consult the official migration guides for detailed instructions.
