v0.5.1

Patch — Restore Certificate.ts as self-contained module, fix docgen compatibility.

• Removed convenience re-exports from Time.ts
• Updated stale @example import paths for flat module structure

v0.5.0

Minor — Flatten module structure to eliminate webpack casing conflicts.

This release changes how modules are organized internally. The public API is preserved, but import paths changed.

Breaking changes:

• Concept-folder subpath imports like @evolution-sdk/evolution/address are removed
• Use the root barrel (import { Address } from "@evolution-sdk/evolution") or wildcard (import * as Address from "@evolution-sdk/evolution/Address")
• MessageSigning renamed to COSE in the root barrel export
• ./plutus, ./cose, and ./blueprint available as subpath imports
• Blueprint barrel uses export * as instead of export *

Migration — step by step:

1. Update subpath imports (most common change):

// Before (v0.4.x) — lowercase folder subpath
import { Address } from "@evolution-sdk/evolution/address"
import { Assets } from "@evolution-sdk/evolution/assets"

// After (v0.5.0) — root barrel or PascalCase wildcard
import { Address, Assets } from "@evolution-sdk/evolution"
// or
import * as Address from "@evolution-sdk/evolution/Address"

2. Rename MessageSigning → COSE:

// Before
import { MessageSigning } from "@evolution-sdk/evolution"

// After
import { COSE } from "@evolution-sdk/evolution"

3. Update Blueprint imports:

// Before — direct exports
import { codegen } from "@evolution-sdk/evolution/blueprint"

// After — namespaced exports
import { Blueprint } from "@evolution-sdk/evolution"
Blueprint.codegen.generateTypeScript(...)

4. Domain subpaths still work (unchanged):

// These still work in v0.5.0
import { Address } from "@evolution-sdk/evolution/plutus"
import { COSESign1 } from "@evolution-sdk/evolution/cose"
import { Codegen } from "@evolution-sdk/evolution/blueprint"

v0.4.0

Minor — Reorganize flat module structure into semantic concept folders.

• Moved ~130 flat root-level files into 24 concept folders following Effect v4 conventions
• Merged datum/ into data/
• Extracted certificate/ from governance/
• Moved byte primitives to bytes/, numeric types to numeric/
• Moved CBOR and Codec to encoding/
• Deleted dead code: Combinator.ts, FormatError.ts, NativeScriptsOLD.ts, Function.ts
• Conway-era certificate encoding fix: tag 258 for nonempty ordered sets

All public API exports preserved via barrel files and package.json exports map.
