**Latest Release**
[https://github.com/UTXOnly/nost-py/tree/v0.6](https://github.com/UTXOnly/nost-py/tree/v0.6)

**Enhancements**
* Obfuscate `client_ip` tag by using a hashed value for their ip address
  * Rate limiter is triggered off the hashed value, no `client ip` in any application logs
* Added docstrings for classes in `websocket_handler.py`
* Remove event verification from `handle_new_event` method (unnecessary as it is done by clients)
* Removed `SQLalchemy` in favor of async `psycopg3`
    * Faster
    * Smaller memory footprint
    * More control over dynamically constructed queries
* Slight redesign of database schema to store `tags `in `JSONB` format
  * Easier to query individual tags
  * Improved query performance from executing `tag` search as a function scan
  * Remove high cardinality `indexes` , leaving indexes only on `pubkey` and `kind`
* `event-handler` service broken up into smaller `async` functions , with better error handling and more specific error messages
* Updated [Database Monitoring setup script](https://github.com/DataDog/Miscellany/tree/master/dbm_setup)

**Bug Fixes**
* Tags not being added to query filter, [Issue #28](https://github.com/UTXOnly/nost-py/issues/28)
  * Tags are now stored in `JSONB` format and use valid and dynamically constructed queries
