# Changes in plop 0.6.0-dev

## Features

- Scale -- split up in frontend, storage and signing nodes. A frontend
  and a storage node use a shared file system for peristent storage of
  log entries, duplicate detection and mapping from merkle tree leaf
  hash to entry (see doc/db.md).
- Message validation -- intercommunication is done over HTTPS with
  message signatures. A URL-based authorization scheme is read from
  node config.
- Docker images -- docker description files for generating docker
  images and hints for deployment.

# Changes in plop 0.1.1 - 2014-09-20

plop version 0.1.1 removes the depency on maps and fixes several major
bugs.

## Bugfixes

- Add a field in the database with the Merkle Tree Leaf hash, for
  get-proof-by-hash (closes CATLFISH-3).
- Do hash the full MerkleTreeLeaf. This bug made the tree head to
  sometimes change after a crash. Found by Tom Fitzhenry.
- Handle unknown hashes in inclusion().
- Make ht:print_tree() print something more useful.
- Add a field in the database with extra-data, for catlfish this holds
  x509 cert chains without the leaf cert.

## Features

- get-entry-and-proof implemented.
