 # 0.3.0 
+- SSL support via OpenSSL
+- Added "Thread Manager" class to allow for multiple (or custom) threading models (process per thread, event loop)
+- Default (and only included) threading model is now event loop
 - Rewrote request parser for readability and speed
+- Rewrote socket system for readability and speed
 - Added improved logging with different log levels
 - Separated anthracite into libanthracite and anthracite-bin to allow for other projects to implement anthracite (example in ./src/api_main.cpp)
 - Cleaned up code and seperated most code into headers & source
 - Revamped build system to use CMake properly
 - Moved CI/CD over to Forgejo
+- Added simple config file system (will be completely replaced by v1.0)
 - General system stability improvements were made to enhance the user's experience
 
-
 ## HTTP Request Parser Rewrite
 
 The following benchmark (source in ./tests/speed_tests.cpp) shows the speed

 # Anthracite
-A simple web server written in C++. Supports HTTP 1.0 & 1.1.
+
+Anthracite is an extensible, low-dependency, fast web server.
 
 ## Developing
 
-To build/develop Anthracite, you must have C++23, CMake, Make, and Python3 installed.
+To build/develop Anthracite, you must have C++20, OpenSSL, CMake, Make, and Python3 installed.
 
 Create a `build/` directory, run `cmake ..`, and then `make` to build.
 
-## Todo
-- [x] HTTP/1.0
-- [x] Serve HTML Pages
-- [x] Properly parse HTTP requests 
-- [x] Add module-based backend system for handling requests
-- [x] Multithreading 
-- [x] HTTP/1.1
-- [x] Enhance logging
-- [x] Create library that can be used to implement custom backends (i.e. webapi, fileserver, etc) 
-- [ ] Faster parsing 
-- [ ] HTTP/2 
-- [ ] Improve benchmarking infrastructure
-- [ ] Fix glaring security issues 
-- [ ] Proper error handling
-- [ ] User configuration
-- [ ] Cleanup (this one will never truly be done) 
+## Features 
+
+- HTTP/1.0 & HTTP/1.1 Support
+- SSL via OpenSSL
+- Event loop thread management
+- libanthracite library for reating custom webservers 
+- Configuration through configuration file
+- Minimal dependencies (only OpenSSL & stantart library so far)
+
+## Roadmap
+- HTTP/2
+- HTTP/3
+- More threading modes
+- Proxy backend
+- Security/Error handling audit
 
 ## Screenshots
