The main change in this version is the removal of the connectiuon retry support. There are 2 main reasons this support has been removed -
- It provided little benefit over the added connection logic complexity. In 90% of cases, a connection which fails on the first attempt fails all subsequent retries. Very rarely does a connection which fails on the first attempt succeed with one of the retry attempts. This approach did have some benefit in the past when networks were slower and often more congested, but advances in technology, network speeds and infrastructure quality mean the sorts of problems we use to encounter and less prevelent.
- The inclusion of retry support significantly complicates the event handling logic and creates some rare, but not unknown, corner cases where events don't get correctly handled and can result in the connection promise handing indefinitely, being neither resolved or rejected. The retry support also had a performance hit which could actually cause connection problems, especially on a slower network using a slower key excahgne or cipher.
The other reason to remove this support is that should someone want to have such support, it can easily be added in their own use case via one of the retry promise packages available and can be tailored to their specific needs. Maintaining a flexible and general implementation which did not have any negative impact is much harder and adds an additional maintenance burdon which is only beneficial for a small number of use cases.
The other change in this version is that we are no longer testing against v18.x of node. Highly recommended that at least version v20.x is used.
