v3.3.11

New Features

• Revert test_nb to sync API using execnb 0.3.2 CaptureShell loop thread, add cell_timeout option and leaked-task warning (#1632)
• Include asyncio task await chains in nbdev-test SIGINT stack dump, so hangs suspended in coroutines show where they are stuck (#1631)
• Show which notebook each worker was running on ctrl-c during nbdev_test, replacing faulthandler with a custom SIGINT handler (#1630)
