## 0.5.8 (2024-11-08)

### Chore

 - <csr-id-d5677604e93c07a5392f4229af94a0b736eca382/> update pinned rust version, clippy lints, remove some dead code

### New Features

 - <csr-id-f7e740fb2ba36d0fcf3fd196d60333552911e3a4/> generalized hash trie indexes for relational tuples
   Generalized Hash Tries are part of the SIGMOD '23 FreeJoin
   [paper](https://dl.acm.org/doi/abs/10.1145/3589295) by
   Wang/Willsey/Suciu. They provide a compressed ("factorized")
   representation of relations. By operating in the factorized domain, join
   algorithms can defer cross-products and achieve asymptotically optimal
   performance.

   `zombie_processes` still on current nightly (`clippy 0.1.84 (4392847410

## 0.5.6 (2024-07-23)

<csr-id-3098f77fd99882aae23c4b31017aa4b761306197/>

### Chore

 - <csr-id-3098f77fd99882aae23c4b31017aa4b761306197/> update pinned rust version to 2024-06-17

### New Features

 - <csr-id-b3d01c20cae2335a3da2c02343debe677f17786b/> add `#[derive(Lattice)]` derive macros, fix #1247
   This adds derive macros to allow user-created macros. Each field must be
   a lattice.
   
   Example usage:
   ```rust
   struct MyLattice<KeySet, Epoch>
   where
   KeySet: Collection,
   Epoch: Ord,
   {
   keys: SetUnion<KeySet>,
   epoch: Max<Epoch>,
   }
   ```
   
   Uses `#[derive(Lattice)]` for the `lattices` library `Pair` lattice.
   Also contains some cleanup in the `lattices` crate.

### Bug Fixes

 - <csr-id-9c834406efcc3839a2a0d48b514146d06bb6e35d/> change fuzz test bounds to require `PartialEq` instead of `Eq`, fix #1302
 - <csr-id-1ad690b993f38ac6a03667fdce56e6603076b1d2/> Make inner for `WithTop` & `WithBot` private
   `Option<T>` is not a lattice, so it is unsafe to expose as public.
   
   I also updated documentation to lead with intention before
   implementation (minor cleanup).
