Bitcoin developers and engineers are continually making improvements to solve critical issues such as scalability and transaction costs. As a result of that, innovations such as SegWit, Lightning Network, and Atomic Multi-Path Payments over Lightning are already in place.
However, even these have to go through multiple iterations to keep up with the everchanging world of crypto. Basically, C-lightning is one of the implementations of Lightning Network.
We're happy to announce the #clightning v0.7.2 "Nakamoto's Pre-approval by US Congress" has just been released!
This release includes dynamic plugin management, support for the upcoming signet, and many many performance improvements and minor fixes.

This implementation has been in production use on the Bitcoin mainnet since early 2018, with the launch of the Blockstream Store. c-lightning only works on Linux and Mac OS, and requires a locally running bitcoin that is fully caught up with the network you're testing on.
According to the tweet, the updated version of c-lightning supports dynamic plugin management as well as “the upcoming signet.” This version is “Nakamoto’s Pre-approval by US Congress,” and is available via GitHub.
Just a month back. Blockstream announced the v0.7.1 release of C-lightning. That version was one of the several technological improvements intended to make Bitcoin lightning network transactions cheaper, faster, and safer.
Their new code release provides an interface that makes it easier for developers to build their own features into the c-lightning code, supporting plugins written in C, Go, and Python. This could be a whole range of things, like monitoring tools or extra channel features. This customizability is one-way-lightning is different than other lightning network implementations, like LND and Eclair.
