# Release Notes for Cyphernetes v0.15.0
This one took a bit longer than our usual release cycle but packs a real punch!

This release includes the biggest refactoring of the codebase to date.
For starters, the heart of Cyphernetes has been fully rewritten from scratch. This release does away with the goyacc dependency as the parser has been reimplemented as a recursive descent function, while the lexer has been rewritten to be more straightforward and maintainable.

This change will allow the parser to deliver better, contextual messages on parsing errors - as well as serving for a better platform for future development of the language.
Next, the single parser Cyphernetes package has been broken down into 3 packages:

core: This is the package that provides the Parse method - It contains the language parser, relationship engine and other parts that together provide that Cyphernetes magic
provider: This is an interface that allows the core package to interface with a data backend - contains functions for doing CRUD operations as well as resolving resource kind names and other schema related functionality
apiserver: A default provider implementation - this is the original K8s go-client used by Cyphernetes up until now.

This change allows for easier integration of the Cyphernetes language into other Go projects and opens up the possibility of including Cyphernetes in products that use other backends that reflect the contents of etcd (e.g. Postgres, Elasticsearch…) for looking up resources.

For the first time, we publish an Integration guide in our docs.
Besides these two major changes, the refactoring job includes many bug fixes, performance improvements and enhancements to usability.
More than anything, we received a lot of user feedback over the past couple of months! Thank you! This helped us address several important issues and come up with feature ideas.


Features

Full rewrite of the core Cyphernetes package
- Support for dry-run mode
Shiny progress bars when initializing resource specs
Add version command
New —format flag for YAML output support in query/shell commands

Improvements


Blazing fast cluster spec initialization
Support fully qualified kinds (e.g. deployments.apps)
Warn on kind ambiguity, present list of available fully-qualified names
Allow access to non-namespaces resources (nodes, namespaces…) without explicitly setting “all-namespaces”
More relationships now discovered automatically

Bug Fixes

Namespace hardcoded to default on web caused missing results when namespace was defined in local Kubernetes context
Ambiguous	resource kinds of different groups crashed the program
- —namespace was ignored by Cyphernetes shell - now takes precedence
