DFX

• feat: add option to specify initial cycles for newly created canisters (#1433)

Added option to dfx canister create and dfx deploy commands: --with-cycles <with-cycles>.
This allows the user to specify the initial cycle balance of a canister created by their wallet.
This option is a no-op for the Sodium network.

dfx canister create --with-cycles 8000000000 some_canister
dfx deploy --with-cycles 8000000000

Help string:

Specifies the initial cycle balance to deposit into the newly
created canister. The specified amount needs to take the
canister create fee into account. This amount is deducted
from the wallet's cycle balance

dfx toolchain default latest
dfx toolchain list
dfx toolchain uninstall latest

Release: 0.6.21

0.6.20

Highlights of what's new in 0.6.20

The0.6.20 release primarily both user-facing and internal enhancements, including fixes and updates to {proglang}, the {proglang} base library, and Candid.

The most significant new features and fixes include the following updates:

• A new notification message that the DFINITY Canister SDK sends anonymous usage data to DFINITY Stiftung by
  default has been added to dfx commands. The notification message is only displayed once, the first time you run any dfx subcommand.
  For example, the first time you run dfx new to create a new project, the notification is displayed before any other project creation messages.

  The purpose of this notification is to inform you that dfx is configured to collect anonymous information about dfx command activity and errors. Collecting anonymous data is enabled by default in an effort to improve the developer experience based on usage patterns and behavior.

  If you want to prevent the collection of data about dfx usage, you can explicitly opt-out by setting the following environment
  variable:

  DFX_TELEMETRY_DISABLED=1
  

  To find out more about the data collected and what your consent means, see the DFINITY Canister SDK Terms and Conditions.

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

  Previously, the --network option required you to specify a network name that matched a network aliases configured in the project's dfx.json file.

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.

0.6.18

Highlights of what’s new in 0.6.18

The 0.6.18 release primarily includes user-visible new features, internal enhancements, and fixes and updates to the version of Motoko and, the Motoko base library that are supported, and Candid.

The most significant new features and fixes include the following updates:

• A fix to dfx upgrade that prevents a main thread panic when Option::unwrap() is called on a None value.

• A fix to the name of the language service command to restore its compatibility with IDEs.

Motoko

• New syntax for option types: Option blocks do ? <block> and option checks <exp> !.

  Inside an option block, an option check validates that its operand expression is not null. If it is, the entire option block is aborted and evaluates to null. This simplifies consecutive null handling by avoiding verbose switch expressions.

  For example, the expression do? { f(x!, y!) + z!.a } evaluates to null if either x, y, or z is null; otherwise, it takes the options' contents and ultimately returns ?r, where r is the result of the addition.

  The argument to a do or do ? expression must be a block { ... }, never a simple expression.
