Update bundled openssl gem to 3.3.0 due to support FIPS

With an old gem, it caused an exception after FIPS enabled in OpenSSL. We have updated the bundled openssl gem to 3.3.0 to solve the issue.

Fix memory leaks when exception was raised frequently with fluent-plugin-elasticsearch

There were memory leaks under conditions where exceptions frequently occurred during communication between Elasticsearch and fluent-plugin-elasticsearch. The issue was fixed in fluent-plugin-elasticsearch v5.4.4 and bundled into fluent-package v5.0.7.

About next LTS schedule

We plan to ship the next LTS version of fluent-package v5.0.8 on September, 2025. The content of updates are still in T.B.D.

End of support for td-agent v4, let's migrate to fluent-package

As it was already announced Drop schedule announcement about EOL of Treasure Agent (td-agent) 4, td-agent v4 reached EOL in Dec, 2023.

After reached EOL, td-agent v4.5.3 on Windows was released because there was a crash bug during startup on Windows. It was backported fix from fluent-package v5 as it is critical in some case. Even though this was a exceptional maintenance release, but there is no change to the fact that we already stopped maintaining td-agent v4.

We strongly recommend migrating from td-agent v4 to fluent-package v5 (LTS). See Upgrade to fluent-package v5
