Netdata v1.45.1 is a patch release to address issues discovered since v1.45.0.

This patch release provides the following bug fixes and updates:

• Ensured proper handling of default values for data collection jobs submitted via dynamic configuration. (#17255, @ilyam8)
• Optimized go.d.plugin service discovery by filtering out irrelevant docker-proxy listeners. (#17254, @ilyam8)
• Improved go.d.plugin's ability to find applications, including those using IPv6, and identify Apache processes more reliably. (#17252, @ilyam8)
• Improved OpenSSL discovery on macOS for Homebrew builds. (#17250, @Ferroin)
• Obsolete references to saving the internal database using the USR1 signal, reflecting the removal of save/map memory modes. (#17249, @ilyam8)
• Added ZSTD compression support for dbengine (disabled by default for now). This improves storage efficiency when available, automatically falling back to uncompressed pages for compatibility. (#17244, @ktsaou)
• Fixed a bug that caused metric reference count errors during release. (#17239, @ktsaou)
• Code cleanup. (#17237, @ktsaou)
• Enabled Gorilla compression by default for dbengine, reducing memory usage. (#17234, @ktsaou)
• Improved dbengine unit tests for better code coverage and maintainability. (#17232, @ktsaou)
• Fixed a database engine cache bug that could cause queries to stop prematurely under pressure. (#17231, @ktsaou)
• Implemented caching optimization to reduce the number of cache flushes following journal file v2 creation. (#17220, @stelfrag)
• Reduced clutter in MySQL/MariaDB query logs by disabling session query logging for the go.d/mysql collector. (#17219, @ilyam8)
• Improved go.d.plugin to correctly identify MariaDB databases. (#17218, @ilyam8)
• Enhanced macOS build stability by using native libraries and optimizing checks for dependencies. (#17216, @Ferroin)
• Suppressed unnecessary compiler warnings about redefined macros, improving build cleanliness and compatibility with stricter build flags. (#17209, @Ferroin)
