0.0.4

• parcel validate CONTRACT: checks a contract compiles. No data needed.
• parcel lint CONTRACT: validates, then reports admit-reads-only-ctx,
  unsatisfiable-callers, constant-rule, duplicate-condition, unused-extension, and
  notes. --deny-warnings exits 1 on warnings.
• --schema is optional for validate, lint and compile. Column types come from the
  binding's local Parquet data, else expose. Without data, a rule reading a column not in
  expose is refused.
• parcel check reports one section per caller: exposed columns, rows received, each policy
  (decide, admit, transform, shape) and each quality rule over the caller's rows, with
  pass rates and the commonest failing values. A refused caller shows the rule, its condition
  and the caller's value. All counts run concurrently, each with a progress bar on a terminal.
• version is a semantic version: 1.0.0, 2.1.0-beta.1. A whole number N reads as N.0.0;
  a decimal such as 1.10 is refused with the fix (1.10.0). parcel_core::Version replaces
  u32 on documents and compiled contracts, and serialises as a string, so contract hashes
  change. ODCS import keeps the full version.
• Rules take an optional message, shown in check output and kept in the compiled report
  (ReportEntry::message). Contracts without it hash as before.
• Every structural problem in a document is reported at once, with its line and a fix.
  ContractDoc::parse_all returns them all.
• Diagnostic has help and line. Messages suggest close names for columns, ctx fields,
  functions and types (integer → int64), name the operation that fits a namespace, and
  catch and, = and is null.
• A whole-number literal beside a double is a double (row.cost > 0); beside an unsigned
  column, unsigned. Only exact literals are converted.
• Output: error[Code] with the source line and help:, aligned columns, colour on
  terminals only (none when piped or with NO_COLOR). parcel with no command prints help.
• compile prints each rule's op and tier; reasons are in --json. An admit that reads
  only ctx is reported as plan time.
• A compiled contract round-trips through bytes: Compilation::to_bytes and
  Compilation::from_bytes (parcel_runtime::compiled). Loading never compiles.
• The parcel-bundle/1 bundle and Bundle::verify, which recompiled it, are removed.
  parcel compile -o writes the compiled bytes. BundledFunction, ColumnDef and the schema
  helpers move to parcel_runtime::compiled.

0.0.3

• Embedding columns: a contract can expose fixed_size_list<float32, N> with a positive
  dimension N. The checker refuses other element types, a zero or negative dimension, and a
  column whose dimension differs from the data's or from the function that produces it.
• CEL and DataFusion both evaluate rules over embeddings and agree, null rows included,
  keeping float32 and the dimension; size works on an embedding.
• A bundle keeps an embedding schema through serialisation and verification, and fails
  verification if the declared dimension is changed.
• WebAssembly functions take and return embeddings: in Rust, parcel_udf::export! accepts
  [f32; N], and function signatures may name fixed_size_list<float32, N>. The host refuses
  output of the wrong dimension or length.
• The residency check and the embedding decoder now pass clippy on Rust 1.98, with no change
  in behaviour.
• 0.0.2 was not published on its own; its changes ship in this release.

0.0.1

• The contract language: seven operations (decide, expose, admit, assert, transform,
  guarantee, shape) over three namespaces (ctx, dataset, row), checked against the
  data's Arrow schema.
• The compiler: CompiledContract, ValidationPlan and WritePlan sharing one hash, and the
  parcel-bundle/1 artifact an engine verifies by recompiling.
• Shapes: small-cell suppression, sampling, and Laplace noise at the row or the aggregate.
• Exports: SQL for seven dialects, Substrait, and ODCS v3 import.
• Tenant functions as WebAssembly modules, pinned by hash.
• The parcel command: check, compile, schema, import odcs, function verify.
• Binaries for Linux, macOS and Windows, with install.sh and install.ps1 installers.
