Claude Code Changelog

[!NOTE] This archive takes some time and money (server, tokens) to run.

I’d appreciate any support – a free follow on X or chipping in a few bucks.

Unofficial, community-maintained tracking of Claude Code prompt and feature-flag evolution across releases.

What's Tracked

cc-prompt.md – legacy compatibility file per tag
cc-flags.md – legacy compatibility file per tag
system-prompts/*.md – extracted prompt artifacts grouped by category (see indeces)
meta/flags.md, meta/metadata.md, meta/cli-surface.md, meta/prompt-stats.md – derived metadata
annotated tags (vX.Y.Z) and GitHub releases for historical navigation

How to Read This Repository

Pick two tags and open compare view:
- https://github.com/marckrenn/claude-code-changelog/compare/v2.1.44...v2.1.45#files_bucket
Use system-prompts/ for per-file prompt artifacts.
Use meta/ for structured summaries and aggregate metrics.
Use Init / Last edit columns as lifecycle hints for each prompt artifact.
For deep full-history research, point a coding agent at this repo directly. GitHub Copilot on github.com is currently limited for broad historical search/analysis.

Data Quality & Interpretation Notes

Token totals and per-file counts are estimates.
Tokenization can vary by model/tokenizer/runtime; small differences are expected.
Aggregate totals are useful directional signals.
Estimated LOC is derived from a prettified bundle line count and is only an approximation.
Prompt files can contain near-duplicates or intentionally duplicated variants.
File names can change across versions (renames/splits/merges), even when content lineage continues.
A single conceptual prompt can appear under multiple files in some releases.
Compare statistical deltas with raw diffs before drawing strong conclusions.
