Developer weekly update August 7, 2024

Hello developers, and welcome to this week's developer weekly update! This week, there is an exciting new beta release of dfx, a reminder about the upcoming online ICP DevConf event, info about the Bitcoin Olympics, and new docs on asset security. Let's get started!

dfx v0.23.0 beta release

dfx v0.23.0 has been released for beta testing! This release includes several new features, including:

• dfx can now be used to generate .env files for Motoko canisters.

• security_policy and disable_security_policy_warning are now supported in the .ic-assets.json5 file. This configuration has three options: "hardened," "standard," or "disabled." Learn more about each setting in the release notes.

• The command dfx info security-policy returns the headers that get applied to assets as configured in the new security_policy setting.

• dfx extension can now install extensions from external locations, such as URLs or a .JSON file, rather than just through the extension's name.

• The replica port is now displayed in the output of dfx start.

• The flag --wallet now accepts an identity name.

• For Rust canisters, crates can be specified in the dfx.json file and used for a canister module.

This release also includes bug fixes such as:

• dfx extension install does not return an error if the extension is already installed.

• dfx ledger create-canister now sets the correct controller principal.

• Error codes are now displayed for some http-related-errors.

You can read the full release notes and install the beta with the command dfxvm install 0.23.0-beta.3.

Asset security documentation

New documentation has been published that details Content Security Policies (CSPs) for asset canisters, security recommendations, and details about changes to the asset canister's default CSP in dfx versions newer than v0.21.0. You can learn more on the developer docs.

That'll wrap up this week. Tune back in next week for more developer updates!
