[dependabot]

Updates the requirements on robotframework-robocop to permit the latest version.

Release notes

Sourced from robotframework-robocop's releases.

v9.0.0

9.0.0 (2026-08-26)

The main focus of the 9.0.0 release is project rules - rules that read the whole project context instead of a single file. We added 12 project rules (argument, import, keyword and variable checks across files) and merged the separate robocop check-project command into the regular robocop check.

Beyond project rules, this is a large release with several other big changes:

• 13 new non-project rules, including a dedicated GROUP syntax category, continue-on-failure tag rules and new spacing/documentation/variable checks.
• Fixes for more than 35 rules, letting Robocop auto-correct many issues and replacing several redundant formatters (leaner formatters focused on alignment and whitespace).
• Plugins - custom rules, formatters, reports and configuration can now be packaged and distributed as plugins.
• Built-in rulesets - reference curated rule sets with extends = ["robocop:minimal"].
• Custom reports - load and enable your own reports just like custom rules and formatters.
• robocop config init - generate a fully documented configuration file.
• Test case [Metadata] support (Robot Framework 7.5) across the linter and the formatter.
• New AlignBDDStatements formatter
• leaner, fixed-width whitespace alignment.
