-## [0.1.0] MVP 1 - 2025-06-23
-The first version with some kind of functionality
+## [MVP v1] - 2025-06-22
 
 ### Added
-- Idea of replacable database engines as architectural basis
-- Interface `SQLEngine`, depicting main functionality, like:
-    - Getting list of existing Databases
-    - Creating Databases
-    - Dropping Databases
-    - Getting snapshot of Databases (by getting their dump)
-    - Executing SQL queries
-- Support for `PostgreSQL` in Playground via `PostgresEngine` (implements `SQLEngine`)
-- Database **Templates System** for saving the state of databases  
-    The idea is that *Template is a snapshot* of database.  
-    Basically it's an object that contains information required to recreate the existing database from a blank one.
-- Basic structure of an API on `Django` and `DjangoREST`
-- Basic frontend on `React`
-- Basic **CI/CD** and `Docker` to deploy easily
-- Some testing of `PostgresEngine` done using `pytest`
