  "textContent": "cel 0.6.0 has been released.\n\ncel is a pure Ruby implementation of Google Common Expression Language,\nGitHub - google/cel-spec: Common Expression Language -- specification and binary representation.\n\nThe Common Expression Language (CEL) implements common semantics for\nexpression evaluation, enabling different applications to more easily\ninteroperate.\n\n\n    require \"cel\"\n\n    # set the environment\n    env = Cel::Environment.new(name: :string, group: :string)\n\n    # parse\n    ast = env.compile('name.startsWith(\"/groups/\" + group)')\n    # check\n    prg = env.program(ast)\n    # evaluate\n    prg.evaluate(name: Cel::String.new(\"/groups/acme.co/documents/secret-stuff\n    \"),\n        group: Cel::String.new(\"acme.co\")) #=> true\n\n    # or do it all in one go\n    env.evaluate('name.startsWith(\"/groups/\" + group)',\n      name: Cel::String.new(\"/groups/acme.co/documents/secret-stuff\"),\n      group: Cel::String.new(\"acme.co\")\n    )\n\n\nHere are the updates since the last release:\n\n## [0.6.0] - 2026-02-28\n\n### Features\n\n#### Network Extension\n\nSupport the network extension, as defined [here](\nlibrary package - k8s.io/apiserver/pkg/cel/library - Go Packages).\n\n### Improvements\n\n#### support top-level lookup (ex: '.y')\n\nalso, make sure than, on lookup, keys under the passed container take\npriority, except in the case where the lookup is top-level\n(i.e. '.y').\n\nat the same time, #merge is refactored in order to:\n\n* normalize nested bindings into aggregated keys ({a:{b:1}} => {:\"a.b\"=> 1}\n* override container-prefixed variables with the local binding\n* deal with conflicts by moving them to top level.",
