Tokio's stall-detection feature was breaking on RHEL/CentOS 8 and Debian 10. Fixed. Java SDK's Foundry client just stopped duplicating path segments.

Tokio shipped a portability fix [1] swapping `libc::gettid()` for raw `syscall(SYS_gettid)` to drop the hard glibc 2.30 dependency that was killing binaries on older enterprises (RHEL 8, Debian 10). The syscall path works on every Linux kernel since 2.4.11 with zero glibc version tax, matching what nix and rustix do internally. On the Java SDK front, the Foundry client was inserting duplicate `/anthropic` path segments when baseUrl already carried the suffix, breaking cross-SDK parity [5]. Fixed. The same SDK also shipped three build infrastructure wins: Gradle 9 migration with Kotlin 2.0 metadata [7], cold compile times cut from 84s to 62s via proper JIT tuning [6], and build-cache portability for JavaExec tasks [8]. Knowledge-work-plugins tightened credential-review scope [2] to catch exfiltration paths in dotdirs and non-loaded plugin surfaces, while Claude Code pushed 2.1.181 with `/config` runtime syntax, Apple Events sandboxing, and Bun 1.4 [3]. Code-modernization plugin now orchestrates agents via Claude's Workflow tool instead of prose fan-out, hardening every subagent against prompt injection from analyzed codebases [4].
