Highlights of what’s new in 0.6.20

The 0.6.20 release has both user-facing and internal enhancements, including fixes and updates to Motoko, the Motoko base library, and Candid.

New features and capabilities

The most significant new features and capabilities include updates in the following functional areas:

• DFX

• Candid

• Motoko

DFX

• The dfx commands that support the --network option have been updated to support URLs when specifying the network value.

Candid

The Candid web interface has been updated to provide easier navigation and a better user experience. The updates to the Candid web interface include the following new features and improvements:

• A new Console drawer provides quick access to method output and a list of all available methods as links for fast navigation.

• Canister methods and their related form elements are more clearly separated and annotated.

• Method output is selectable and easier to toggle between text, UI, and JSON formats.

• The layout is now responsive to provide an optimized display when viewing service using mobile devices or other media.

Motoko

• The Motoko base documentation examples are now executable in the browser.

• The Motoko compiler supports specifying command-line arguments using --args <file> and --args0 <file>.

  The new options enable the compiler to read newline and NUL terminated arguments from a specified file name.
