What happened

Elastic published multiple blog posts including release announcements for Elastic Stack 8.19.15 and 9.3.4 (30 Apr 2026). Both releases are recommended upgrades and address a regression where APM’s HTTP/2 connections could fail with strict clients due to framing errors. No security vulnerabilities or CVE identifiers are disclosed in these notices. The feed also contains numerous non-security product, partnership, and thought-leadership posts (observability, AI/LLM, cloud features, serverless, and GovCloud/FedRAMP topics).
