> Claude Code v2.0.53, released 25 Nov 2025 (2025-11-25). 3 entries read out of the shipped bundle. Unofficial, and not affiliated with Anthropic.

Web version: https://changelogs.core-directive.com/v/2.0.53

This is a maintenance release with internal code improvements. The primary user-facing change is improved handling of OAuth token expiration when fetching API usage data, which prevents unnecessary errors during token refresh periods.

## Changes

### OAuth Token Expiration Handling for Usage Data

**What:** The API usage data fetcher now checks if the OAuth token is expiring before making API calls, gracefully falling back to cached data instead of throwing errors.

**Details:**

- Previously, the usage data fetch (`VPA()` at line 471623) would attempt API calls even with expiring tokens, potentially causing "Failed to load usage data" errors
- Now checks if token expires within 5 minutes and returns `null` immediately if so
- Falls back to cached usage data rather than displaying errors during token refresh windows
- **Evidence**: `VPA()` at line 471623-471636 in v2.0.53, new check using `W6()` (OAuth token getter at line 163812) and `Ym()` (expiration checker at line 67497)

**User impact:** Fewer transient error messages when viewing API usage near token expiration times.

### Import Statement Reorganization

The codebase underwent significant refactoring of import statements, moving from default imports to named imports for better tree-shaking and code organization. This affects ~16 import statements but has no user-facing impact.

Examples of changes:

- `import from "stream"` → `import { PassThrough } from "stream"` (line 514212)
- `import from "crypto"` → `import { createHash, randomBytes } from "crypto"` (line 323718)
- `import from "node:fs"` → `import { readFileSync, existsSync, mkdirSync, readdirSync } from "node:fs"` (line 232383)

### Variable Renaming

817 internal variable and function names were renamed as part of minification/obfuscation changes. No functional impact.
