From ae59a5e88aab27276945dc9a1b07c13adeba3983 Mon Sep 17 00:00:00 2001 From: Lukasz Raczylo Date: Thu, 16 Oct 2025 10:56:28 +0100 Subject: [PATCH] 0.7.10 (#80) * Add ability to disable replay protection. - This is useful for runs with multiple traefik replicas to avoid false positives and tokens re-creation. * Enhance the CI/CD pipelines * Increase test coverage. * Update vendored dependencies. * Update behaviour on forceHTTPS as per issue #82 --- .github/CODEOWNERS | 38 + .github/PULL_REQUEST_TEMPLATE.md | 123 +++ .github/dependabot.yml | 52 ++ .github/workflows/.gitattributes
