Note: This change log is incomplete. I started it quite late, as interest in the libraries started to warrant better documentation of any changes made.
Although the libraries in this repo are designed to work together, they are also designed to work separately. Hence, the change logs for each library are managed separately. Here are the different libraries and changes:
Lib-React (libreact) - The Reactor library.
Lib-Sock (libsock) - The socket helper library (development incomplete).
Lib-Async (libasync) - The thread pool and tasking library.
Lib-Server (lib-server) - The server writing library.
MiniCrypt (mini-crypt) - Common simple crypto library (development incomplete).
HTTP Protocol (http) - including HttpRequest, HttpResponse etc'.
Websocket extension (mini-crypt) - Websocket Protocol for the basic HTTP implementation provided.
Changes I plan to make in future versions:
I plan to change the pool (request pool, packet pool, etc') implementations for the different libraries, so as to minimize any possible memory fragmentation that occur when malloc and free are used.
Once I‘m done, I’ll deprecate the objpool library.
Review code for use of Atomic types when Mutex use is avoidable (especially libsock, lib-server and libasync).
Remove / fix server task container pooling (FDTask and GroupTask pools).
I attempt to follow semantic versioning, except that the libraries are still under development, so version numbers get updated only when a significant change occurs.
Libraries with versions less then 0.1.0 have missing features (i.e. libsock is missing the connect implementation and mini-crypt is missing almost everything except what little published functions it offers).
Minor bug fixes, implementation optimizations and short git push corrections (I pushed bad code and fixed it in the same day or two) might not prompt a change in version numbers (not even the really minor ones).
Significant issue fixes cause the tiny version to bump.
API breaking changes always cause version bumps (could be a tiny version bump for tiny API changes).
... In other words, since these libraries are still being developed, test before adopting any updates.
Baseline (changes not logged before this point in time).
The use of sock_free_packet is now required for any unused Packet object pointers checked out using sock_checkout_packet.
This requirement allows the pool management to minimize memory fragmentation for long running processes.
libsock memory requirements are now higher, as the user land buffer's Packet memory pool is pre-allocated to minimize memory fragmentation.
Corrected documentation mistakes, such as the one stating that the sock_send_packet function will not handle the Packet object's memory on error (it does handle the memory, always).

There was a chance that the on_data callback might return after the connection was disconnected and a new connection was established for the same fd. This could have caused the busy flag to be cleared even if the new connection was actually busy. This potential issue had been fixed by checking the connection against the UUID counter before clearing the busy flag.
reminder: The Server.rw_hooks feature is deprecated. Use libsock's TLC (Transport Layer Callbacks) features instead.
