* rewrote request parser, now more simplified and theoretically faster
* added gtest and an example test to measure parser times

+# 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 
+improvements made between 0.2.0 and 0.3.0, as well as comparison to boost's 
+parsing library. 
+
+It should probably be noted that Boost's parser can do a lot more than mine 
+and is likely slower for good reason. Also, these were single runs but 
+subsequent runs showed similar results.
+
+| Parser Tested      | RPS          |
+|--------------------|--------------|
+| Anthracite 0.2.0   | 688,042      |
+| Anthracite 0.3.0   | 27,027,000   |
+| Boost Beast        | 1,023,230    |
+
+# 0.2.0 Fifth Pre-Release
+- Added true HTTP/1.1 support with persistent connections
+- Added HTTP/1.0 vs HTTP/1.1 test to benchmarking suite
+- Slight improvements to benchmarking
+- Added version number information to binaries at build-time
+- Added error page generation build step
+- GitHub CI pipeline will now tag the version when publishing the container to the registry
+- General system stability improvements were made to enhance the user's experience
+
+## HTTP/1.1 Speed improvements
+The following benchmark shows the speed improvements created by implementing
+persistent connections with HTTP/1.1. This test measures the time it takes to 
+request a 222 byte file 10,000 times by one user 
+
+```
+=====[ Anthracite Benchmarking Tool ]=====
+Requests     : 10000

+
+
+HTTP/1.0 Total Time: 3.1160 seconds
+HTTP/1.1 Total Time: 0.3621 seconds
+```
+
+## Benchmark Results
+Each benchmark makes 1000 requests requesting a 50MB file using 
+100 users to the webserver running in a Docker container.
+
+This is a change from previous benchmarks which used a large html
+file.

 # Anthracite
-A simple web server written in C++
 
-## Module-Based Backends
-Anthracite includes (read: will include) system for allowing different "backend modules" to handle requests.
-This allows for anthracite to be extended for additional use-cases. For example, the following
-backends could be implemented: 
+Anthracite is an extensible, low-dependency, fast web server.
 
-- File: Return files from a directory 
-- Reverse Proxy: Pass the request to another server 
-- Web Framework: Pass the request into an application built on your favorite web framework 
+## Developing
 
-## Building & Debugging
+To build/develop Anthracite, you must have C++20, OpenSSL, CMake, Make, and Python3 installed.
 
-Once you have the repository cloned, you can run the following command to build Anthracite:
+Create a `build/` directory, run `cmake ..`, and then `make` to build.
 
-```shell
-make build
-```
+## Features 
 
-It will create a binary file named `./anthracite`
+- 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)
 
-To save time, you can use the following command to build and run anthracite on port `8080`:
-
-```shell
-make run
-```
-
-To save time again, you can use the following command to build and debug anthracite in gdb:
-
-```shell
-make debug
-```
-
-## Usage
-
-Run the following commands to serve all files located in `./www/`:
-
-```shell
-./anthracite [PORT_NUMBER]
-```
-
-## Todo
-- [x] Serve HTML Pages
-- [x] Properly parse HTTP requests 
-- [x] Add module-based backend system for handling requests
-- [x] Multithreading 
-- [ ] Cleanup (this one will never truly be done) 
-- [ ] Proper error handling
-- [ ] Build out module-based backend system for handling requests
-- [ ] Fix glaring security issues 
-- [ ] Faster parsing 
-- [ ] Speed optimizations such as keeping the most visited html pages in memory 
-- [ ] Cleanup codebase 
-- [ ] Enable cache support 
-- [ ] Support newer HTTP versions 
+## Roadmap
+- HTTP/2
+- HTTP/3
+- More threading modes
+- Proxy backend
+- Security/Error handling audit
