# lodash-es breaking changes

Every breaking API change we have recorded in lodash-es on npm: 3 breaking changes in 1 version. Below are its newest version, removals and renames first, each with its source.

Newest change March 31, 2026

## 4.18.0

3 breaking changes, first published March 31, 2026.

- **Behavior changed** `_.omit`  

Paths using constructor or prototype as non-terminal keys are now refused. Calls that used to delete a built-in prototype property now return false and leave the target unchanged, so code relying on that deletion must change. [github.com](https://github.com/lodash/lodash/releases/tag/4.18.0)
- **Behavior changed** `_.template`  

Keys in the imports option containing forbidden identifier characters now throw an error instead of being accepted. Code that passes such keys must rename them. [github.com](https://github.com/lodash/lodash/releases/tag/4.18.0)
- **Behavior changed** `_.unset`  

Paths using constructor or prototype as non-terminal keys are now refused. Calls that used to delete a built-in prototype property now return false and leave the target unchanged, so code relying on that deletion must change. [github.com](https://github.com/lodash/lodash/releases/tag/4.18.0)

## Check your code

These are the changes. To see which of them reach your code, [scan a public repository](https://since.dev/scan.md), or have your coding agent call `check_code` with your manifest or lockfile over [MCP](https://since.dev/docs.md#mcp). [The API](https://since.dev/docs.md#api) reads every change in every version, not only the newest. On Team and up, a fix pull request opens for the changes that reach a connected repository. Nothing merges or deploys.

## Put your code on continuous management.

Scan a public repository now, or give your agent one line.

### See how out of date your code is.

[Scan a repository](https://since.dev/scan.md). Any public GitHub repository. No sign-in.

### Tell your agent what changed since it was trained.

`claude mcp add --transport http since https://api.since.dev/mcp`
