🔧 Bug Fixes & Patches (2)
- Using `cy.contains()` with a regexp argument is now properly escaped. Fixes #1322.
- Fixed a runaway regexp causing large `.js` files to take dozens of seconds to process. This was a regression caused by `2.0.0` with the new `modifyObstructiveCode` option. We've optimized the regexp and the performance is back to being almost identical to transparently passing responses through. Fixes #1330.
