openstack/storlets — Week of 2026-09-12

Java runtime refresh. The largest change swaps out json-simple for gson in the Java-side storlet handling (1004666), and Java dependencies were bumped alongside a small refactor of the string:string hash parsing. Together these move the JVM half of storlets onto a more actively maintained JSON library and newer library baselines.

DevStack and tooling. The DevStack plugin trimmed its user-option surface and dropped a set of shell scripts in favour of direct Python module executions, shedding roughly 30 lines from the install path. A stale workaround for an old install_docker script was removed, and tox lost a redundant passenv entry. Several unused variables were also cleaned out of the tree.

Release plumbing. The 18.0.0 release note landed, and .gitreview plus TOX_CONSTRAINTS_FILE were updated for the new stable/2026.2 branch.
