+
+Hello developers, and welcome to this week's developer weekly update! This week, there is a pre-release of Motoko `v0.14.0`, a new beta release of `dfx`, and new proposals for SNS updates. Let's get started!
+
+## Motoko v0.14.0
+
+A new Motoko version has been pre-released and is available for testing on the [Motoko playground](https://play.motoko.org/)!
+
+This new version includes:
+
+- Add `.values()` as an alias to `.vals()` for arrays and Blobs.
+- Support explicit, safe migration of persistent data allowing arbitrary transformations on a selected subset of stable variables.
+- Additional static checks warn against possible data loss.
+
+[View the forum post](https://forum.dfinity.org/t/pre-release-moc-0-14-0-available-in-playground/40857) and [full release notes](https://github.com/dfinity/motoko/releases) for more details.
+
+## dfx v0.25.0-beta.1
+
+A new release of `dfx` is ready for beta testing! This release is jam-packed with new features and bug fixes. A small sample of new features includes:
+
+- Streamlined output for asset synchronization.
+- `dfx info pocketic-config-port`.
+- Streamlined output for `dfx new`.
+- Impersonating sender of requests to a local PocketIC instance.
+- `dfx canister [create|update-settings] --wasm-memory-threshold`.
+- `dfx start --pocketic` supports `--force` and shared networks.
+- Error when using insecure identity on the mainnet.
+
+Some of the bug fixes include:
+
+- `dfx canister install` and `dfx deploy with --no-asset-upgrade` no longer hang indefinitely when Wasm is not up to date.
+- Correctly detects hyphenated Rust bin crates.
+- `dfx` downloads `.did` files for remote canisters.
+- Template frontends now have unsupported browser warnings, specifically for default security headers that cause Safari to break when viewing local canisters.
+- `dfx deploy --by-proposal` no longer sends chunk data in `ProposeCommitBatch`.
+- All commands with `--all` parameter skip remote canisters.
+
+[Read the full release notes](https://github.com/dfinity/sdk/releases/tag/0.25.0-beta.1).
+
+## Proposals for SNS changes
+
+Two new proposals have been submitted for SNS updates. These proposals are [135067](https://dashboard.internetcomputer.org/proposal/135067) and [135066](https://dashboard.internetcomputer.org/proposal/135066). These proposals include:
+
+- Enable SNSes to opt in for [automatically advancing its target version](https://forum.dfinity.org/t/proposal-opt-in-mechanism-for-automatic-sns-target-version-advancement/39874)
+to the newest version blessed by the NNS.
+
+- Do not redact chunked Wasm data in `ProposalInfo`.
+
+- The `LogVisibility` returned from `canister_status` has one more variant `allowed_viewers`, consistent with the corresponding management canister API.
+
