Remix Release v1.4.0
The Big News
Osaka Upgrade in Remix VM
New Toaster Position
Easier Verification with Etherscan
Improved Autocomplete for TS/JS
Remix VM Default EVM Version Is Now Osaka
The latest EVM upgrade occurred last week bringing in the Osaka. We’ve updated Remix to default to this latest version. The EVM version is selected in the Solidity Compiler in the Advanced Configurations section.
If you are feeling old fashioned, you can select a previous version.
Toasters Now Appear in the Upper Right
Toasters are single notifications that usually come up from the bottom of the screen - like a piece of toast. Notifications tend to come on the upper right of the screen and can be stacked up. We are changing our Toaster notifications to become Notifications.
The new Toaster…I mean Notification, does not stay onscreen for long and its color does not stand out from the rest of the screen - which won’t be a problem for those possessing sensitive peripheral vision. For the rest of us, help will come in the next release.
Easier Verification with Etherscan
In the last release, we added the option to Deploy & Verify in the Deploy & Run Transactions plugin. To Verify on Etherscan, you had to add your Etherscan API key in the Connected Services section of the Settings panel. In this release, you can still add your Etherscan API key there, but you can also add it to the Settings tab of the Contract Verification plugin.
Improved Autocompletion for TS/JS Files
We’ve added a dynamic type acquisition system to significantly improve autocompletion in TypeScript and JavaScript files.
Previously, the editor relied on static, bundled type definitions (web-types.ts), which could contain outdated information. Now, when a user imports an NPM package like:
import { createPublicClient } from ‘viem’
Remix automatically fetches the corresponding type definitions and their dependencies from the jsdelivr CDN. These types are then injected into the editor, which will deliver better autocompletion for a wider range of libraries.
