# Claude Code v2.0.25

> Claude Code v2.0.25, released 21 Oct 2025 (2025-10-21). 6 entries read out of the shipped bundle. Unofficial, and not affiliated with Anthropic.

Web version: https://changelogs.core-directive.com/v/2.0.25

Version 2.0.25 introduces session-only plugin loading via `--plugin-dir`, adds session titles to memory templates for better organization, and enhances editor integration with Sublime Text wait flag support.

## Changes

### Session-Only Plugin Loading

**What:** Load plugins from local directories for the current session without permanently installing them **How to use:**

`# Load plugins from one or more directories claude --plugin-dir ./my-plugins --plugin-dir ../shared-plugins # Plugins are active only for this session claude --plugin-dir /path/to/custom/plugins chat` **Details:**

- Plugins loaded with `--plugin-dir` are marked with `@inline` source designation
- Multiple plugin directories can be specified by repeating the flag
- Plugins are loaded after standard installed plugins
- Path validation occurs before loading - non-existent paths are logged and skipped
- Session plugins persist only for the current command execution
- **Evidence**: `Td6()` function at line 264116, `GQA()` at line 3778, `YQA()` at line 3781, CLI option at line 475753 in v2.0.25

### Session Title in Memory Template

**What:** Session memory now includes a dedicated title section for quick identification **How to use:** The session memory agent automatically generates a "Session Title" section when creating or updating session notes:

`# Session Title _A short and distinctive 5-10 word descriptive title for the session. Super info dense, no filler_` **Details:**

- Appears as the first section in session memory notes
- Designed to be information-dense and distinctive
- Makes it easier to identify and navigate between different work sessions
- Complements the existing 7 sections (Task specification, Files and Functions, etc.)
- **Evidence**: Template variable `ng8` at line 467211 in v2.0.25 (vs `dg8` at line 467131 in v2.0.24)

### Environment Variable for Session Memory Model Selection

**What:** Control which AI model handles session memory updates via environment variable **How to use:**

`# Use Haiku for faster, more cost-effective session memory updates export USE_HAIKU_SESSION_MEMORY=1 claude chat # Default behavior (Sonnet) - no environment variable needed claude chat` **Details:**

- Defaults to Sonnet for highest quality session memory extraction
- Set `USE_HAIKU_SESSION_MEMORY=1` to use Haiku for faster, cheaper updates
- Useful for rapid iteration or cost-conscious workflows
- **Evidence**: `Gu8()` function at line 467294 in v2.0.25 uses conditional model selection vs inline object at line 467224 in v2.0.24

### Enhanced Editor Wait Flag Support

**What:** Improved external editor integration now supports Sublime Text with proper blocking behavior **Details:**

- VS Code continues to use `code -w` for blocking behavior
- Sublime Text now properly configured with `subl --wait`
- Refactored from inline conditional to extensible configuration map
- Makes future editor additions straightforward
- **Evidence**: `Fy8` configuration map at line 431215 with usage at line 431189 in v2.0.25 vs inline ternary at line 431126 in v2.0.24

### Debug Log Path Display

**What:** Debug mode now shows the actual log file path instead of the symlink **Details:**

- Previously displayed: `~/.claude/debug/latest` (symlink)
- Now displays: `~/.claude/debug/1234567890.txt` (actual file)
- Makes it clearer which specific file is being written to
- Improves troubleshooting when multiple debug sessions exist
- **Evidence**: `fc()` function at line 3821 used at lines 441483 and 441622 in v2.0.25

## Internal Improvements

- Refactored Node.js module imports for better code organization
- Separated session memory template structure from update instructions
- Streamlined debug logging path resolution logic
