Will there be any other components with a 4.5 release, or just the
httpclient?  I'm specifically interested in httpcore and httpmime.

Thanks,

These are obviously the wrong release notes. There right ones are here:

About HttpComponents HttpClient

The Hyper-Text Transfer Protocol (HTTP) is perhaps the most significant
protocol used on the Internet today. Web services, network-enabled
appliances and the growth of network computing continue to expand the
role of the HTTP protocol beyond user-driven web browsers, while
increasing the number of applications that require HTTP support.

Although the java.net package provides basic functionality for accessing
resources via HTTP, it doesn't provide the full flexibility or
functionality needed by many applications. HttpClient seeks to fill this
void by providing an efficient, up-to-date, and feature-rich package
implementing the client side of the most recent HTTP standards and
recommendations.

Designed for extension while providing robust support for the base HTTP
protocol, HttpClient may be of interest to anyone building HTTP-aware
client applications such as web browsers, web service clients, or
systems that leverage or extend the HTTP protocol for distributed
communication.

Connections in TIME_WAIT are perfectly normal depending on your OS
systems and do not represent an issue with HttpClient resource
management.
