+# Developer weekly update May 8, 2024

+
+Hello developers, and welcome to this week's developer weekly update! In this week's update, we have a new release of `dfx`, a new release of PocketIC, and a call for feedback from the development team behind Azle. Let's get started!
+
+## `dfx v0.20.0` has been released!
+
+This week, a new version of `dfx`, v`0.20.0` has been released! You can download and install this latest version with the commands:
+
+```
+dfxvm install 0.20.0
+dfxvm default 0.20.0
+```
+
+This release comes with several new features and bug fixes, including:
+
+- A fix for `CANISTER_CANDID_PATH_<canister name>` to be set properly for remote canister declarations.
+
+- A new way to display the JSON schema for `dfx` metadata through the command `dfx schema --for dfx-metadata`.
+
+- `dfx` metadata has been extended with the object `tech_stack`.
+
+- The `dfx completion` command has been added, which generates shell completion scripts for bash, elvish, fish, zsh, or PowerShell.
+
+- `dfx` will no longer create a `.dfx` directory if `dfx.json` is present.
+
+You can read the full [release notes](https://github.com/dfinity/sdk/releases/tag/0.20.0).
+
+Run into a bug? Let us know on the [developer forum](https://forum.dfinity.org/t/dfx-0-20-0-is-promoted/30471).
+
+## PocketIC version 4 has been released!
+
+PocketIC v4 has been release, introducing new capability with agent-based tools through HTTP compatibility. This release also enables you to browse frontend canisters while they are running on PocketIC and make concurrent update calls!
+
+To use the HTTP compatibility, you need to explicitly make an instance live by calling `make_live(...)` on it which does the following:
+
+- Launches a thread that calls `tick()` and `advance_time(...)` on the instance several times per second.
+
+- Creates a gateway similar to icx-proxy which points to the live instance.
+
+- Returns a gateway URL which can then be passed to tools using HTTP, such as agents.
+
+To use concurrent update calls, an `update_call` can be expressed with a new method such as:
+
+```
+let message_id = pic.submit_call(..., payload)?;
+pic.await_call(message_id)
+```
+
+You can read the full details of the release on [the developer forum](https://forum.dfinity.org/t/pocketic-version-4-0-0-ic-http-interface-compatibility/30281).
+
+
