Walkthrough

This change set spans multiple packages and files to update configuration settings, dependency versions, and schema validation logic across the codebase. It renames ISO-format identifiers to simpler strings, removes the deprecated .and() method in favor of z.intersection(), and adds new functions and types for CIDR validation. Core utilities are refactored to use native methods, and documentation is updated to reflect these API changes and improved bundle metrics.

Changes

File(s)	Change Summary
.npmrc, global rollup.config.js	Commented out prefer-workspace-packages in .npmrc; updated Rollup config to use custom conditions (empty object/customConditions added).
Root & Package package.json files	Updated version numbers (e.g., from 3.24.2 to 4.0.0) and added a new dependency alias "zod3": "npm:zod@^3.24.0" in the treeshake package.
packages/core/src/api.ts, checks.ts, locales, regexes.ts, schemas.ts, to-json-schema.ts, util.ts, zsf.ts	Renamed ISO format strings (e.g. "iso_datetime" → "datetime") and corresponding keys; added new CIDR functions (_cidrv4, _cidrv6) with types; updated regex patterns; removed .and() method.
packages/docs/content/**.mdx	Removed references to the deprecated .and() method; documented new CIDR methods, updated bundle size metrics, and noted additional API changes.
packages/mini/src/iso.ts, schemas.ts	Updated ISO type parameters from specific ISO strings to generic formats; added new CIDR interfaces and helper functions.
packages/treeshake/**	Refactored validation framework in out.js (added new classes/functions, removed old config functions); updated treeshake Rollup config; added new boolean demo files.
packages/zod/src/errors.ts, schemas.ts, tests (interface, intersection, json-schema, object, string, template-literal)	Adjusted error inheritance; removed .and() and introduced new CIDR methods; updated tests to use z.intersection() and validate the new generic format strings and CIDR validations.
Miscellaneous (e.g. play.ts, packages/tsc/bench/strongly-connected.ts)	Added a new object schema extension in play.ts; minor formatting adjustments (additional blank lines) in benchmark files.

Poem

I'm a rabbit, hopping through lines of code,
New CIDR checks and cleaner formats now bestowed.
ISO strings shed their old "iso_" skin,
And intersections form where once .and() had been.
With every commit, my ears perk in delight,
Coding in wonder from morning 'til night! 🐰

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
