# v0.18.0
## Major Features
## Execution Environments
- [Add the Poseidon merkle tree specification to our merkle tree](https://github.com/anoma/anoma/pull/677)
- [Add binding signature verification in Cairo backend](https://github.com/anoma/anoma/pull/695)
- [Resource logic check in the Cairo backend](https://github.com/anoma/anoma/pull/696)
## CLI Changes
- [When submitting a resource machine transaction, nullifiers and commitments are printed](https://github.com/anoma/anoma/pull/641)
- [Add the ability to check for commitments in the CLi](https://github.com/anoma/anoma/pull/674)
  + Note that one could do this via the RO backend, but that is not ready yet.
- [Add the ability to check for nullifiers in the CLi](https://github.com/anoma/anoma/pull/675)
- [Read Only Cli Command](https://github.com/anoma/anoma/pull/681)
## Documentation
- [Add a glossary index for our codebase](https://github.com/anoma/anoma/pull/659)
## Bug Fixes
- [Fixed a bug where trying to use Juvix transactions would cause nock translation to fail](https://github.com/anoma/anoma/pull/500)
- [Made workers temporary rather than transient](https://github.com/anoma/anoma/pull/640)
  + this keeps the worker from spewing lots of noise on death or
    trying a restart loop.
- [Fixed the encoding of the empty to be 0 in atom transformation](https://github.com/anoma/anoma/pull/656)
  + This causes the failure of jamming transactions typically as [] is
    typically sent via the round-trip and fail.
- [Fix List Nock to Erlang to encode the empty list properly](https://github.com/anoma/anoma/pull/666)
- [Transactions via the CLI are now jammed before being sent over](https://github.com/anoma/anoma/pull/669)
  + This fixes a bug for larger contracts as they would hit the 1 MB
    transaction limit.

- [Add the hash(sha256) of the transparent nullifer to storage](https://github.com/anoma/anoma/pull/668)
- [Store the binary representation of the ID in storage](https://github.com/anoma/anoma/pull/658)
  + This is a nock compatible format, and useful when we completely
    normalize storage
## Debugging/Examples
- [Made Example Storage not cache](https://github.com/anoma/anoma/pull/662)
- [Fix the Dumper Example randomly dying due to trying to dump the wrong node](https://github.com/anoma/anoma/pull/680)

- [better docs path creation](https://github.com/anoma/anoma/pull/693)

# v0.17.0

  + This makes addresses much nicer to work with and allows better
    changes in the future
- [Workers are engines](https://github.com/anoma/anoma/pull/513)

- [Cairo backend](https://github.com/anoma/anoma/pull/496)
  + This is a preview feature, as it does not currently check resource
    logics, however it does include a test showing it works with a compliance circuit
- [Read only backend](https://github.com/anoma/anoma/pull/597)
  + This is a read only backend. This is not enabled via the CLI yet,
    but is fully usable.

## Bug Fixes

### Typing Fixes
- [Fixing the type on getting namespace from storage](https://github.com/anoma/anoma/pull/627)
- [Fix the typing on the identity manager](https://github.com/anoma/anoma/pull/607)
  + They were incorrect and also overly constrained the type
- [We did not cover the full type range of adding namespaces](https://github.com/anoma/anoma/pull/625)

### Minor Bug Fixes
- [Properly update the counter on the dumper](https://github.com/anoma/anoma/pull/626)
- [Fix the Pinger Test Waiting](https://github.com/anoma/anoma/pull/630)

## Internal Changes
- [Pray Macro Improvements](https://github.com/anoma/anoma/pull/601)
- [Add a symbol utility module](https://github.com/anoma/anoma/pull/588)
- [Remove the intent module](https://github.com/anoma/anoma/pull/581)
- [Remove the write at functionality of storage](https://github.com/anoma/anoma/pull/595)

## Debugging/Helpers
- [Add the ability to get storage from `Anoma.Node`](https://github.com/anoma/anoma/pull/603)

# v0.16.0

## Major Features
- [We now have a new `debug` mode that makes tests pry on failure!](https://github.com/anoma/anoma/pull/525)
- [Resources kinds are now computed with the standard nock jam algorithm](https://github.com/anoma/anoma/pull/497)
- [Nullifiers now use a detatched signature](https://github.com/anoma/anoma/pull/503)
  + The format is now  `jam([jammed-nullified-resource detatched-signature])`.
    * I.E. jamming the resource and signing over the
      nullified-resource, and jamming both together
- [submit-rm client command](https://github.com/anoma/anoma/pull/519)
  + This means that RM backend submissions can be submitted via the cli!
- [New rational on testing](https://github.com/anoma/anoma/pull/558)
  + This means we will now focus on providing examples over future
    tests. Later work will come to deprecate the old testing
    documents, and write new ones about examples instead.
    * A big thanks to [JExample](https://scg.unibe.ch/research/jexample) and [Glamorous Toolkit](https://gtoolkit.com/) for inspiration.
- [New Style guide covering what every contirbutor must know if they want their changes accepted!!!](https://github.com/anoma/anoma/pull/575)
- Examples are now in the codebase! [[1](https://github.com/anoma/anoma/pull/560)] [[2](https://github.com/anoma/anoma/pull/561)] [[3](https://github.com/anoma/anoma/pull/564)] [[4](https://github.com/anoma/anoma/pull/565)]
  + Not all tests have been converted but the resource and nock files
    have been with work started on the node as well.

## Documentation
- For the more important documentation changes see the `Major Features` section.
- [Add documentation on some of the configuration logic](https://github.com/anoma/anoma/pull/534)

## Bug Fixes
- [Fixed random test failure](https://github.com/anoma/anoma/pull/570)
  + This was caused by 2 issues.
    1. The file name could contain the `\` character
    2. The code would not properly wait for the socket file to be
       created as it was asynchronous, this was mitigated by making
       sure the transport responds back
- [Fix bug where the configuration type was improperly typed, made more clear by refactoring](https://github.com/anoma/anoma/pull/501)
- [Bignums can now successfully be sent by our serialization](https://github.com/anoma/anoma/pull/552)
- [Fix double insertion for the same nullifier set](https://github.com/anoma/anoma/pull/559)
  + This bug would occur when we don't scry in a resource transaction,
    as the check happens for the nullifier doesn't want to see the
    complete nullifier set.
- [Fix a bug where the atom represnetation would change the specifics of jamming](https://github.com/anoma/anoma/pull/551)
  + This would cause some issues in kind calculation depending on
    where we ran it, [causing interesting errors](https://github.com/anoma/anoma/issues/550).
- [Fix TOC generation](https://github.com/anoma/anoma/pull/556)
  + There were two issues. The first being going up 2 levels caused
    the TOC to be improperly generated. Worse is that spacing was not
    considered for the markdown format when numbering got past 10.
    * [Seems that this even affected livebook itself!](https://github.com/livebook-dev/livebook/issues/2659)

## Internal Changes

- [Freeing up unused code and cleaning out the Node folder](https://github.com/anoma/anoma/pull/516)

- Minor Code Improvements [[1](https://github.com/anoma/anoma/pull/535)] [[2](https://github.com/anoma/anoma/pull/573)] [[3](https://github.com/anoma/anoma/pull/544)] [[4](https://github.com/anoma/anoma/pull/541)]
- Made functions that start the node take options instead of adhoc arguments [[1](https://github.com/anoma/anoma/pull/545)] [[2](https://github.com/anoma/anoma/pull/542)]
- [Made tests respect that they are tests and not overwrite the sockets produced in prod or dev mode](https://github.com/anoma/anoma/pull/536)
