Dev Kernels 0.2.0: Major Enhancement on Execution Logic and Bug Fixes

[allen-li1231]

Added

• Notebook cells now can run in parallel, and user can toggle run mode, either in parallel or sequential, in settings.
• Previously local notebook changes were periodically updated to server, but not vice versa. Now notebook can be updated to its server version whenever it is opened or corresponding window is activated.

Fixed

• Missing proxy credential protocol setting
• Bug that causes code interrupt to fail the extension.
• Bug that causes extension to fail when interrupting note.
• Bug that causes tracking on cell execution to be falsely ended when paragraph run status is pending.
• Bug that causes error output when execution an empty cell

Changed

• Remove logic of locking zpln files, as it causes misunderstanding and potentially causes problem when multiple notebooks are opened
