Release Notes

A broadcast producer can wait for its readers. A consumer registers at the head, so anything published before it registered is lost to it and nothing reports that: the push succeeds, and a reader that started late looks exactly like one that is slow. WaitForConsumers closes that window and answers how many readers are present when the wait ends, so a shortfall is a number rather than a hang. Lag now answers $null instead of a number when the id names no live consumer, which covers an id past the table and one that has been given back; a script that only ever passes a registered id sees no change. The module also has a documentation surface it did not have: a reference generated from the module's own help covering all 135 cmdlets and 118 classes, a page showing what each value actually looks like when a scenario is run against the built module, and a guide covering installing, choosing a structure, runspaces and lifetimes, bridging two hosts and troubleshooting. Every cmdlet, class, enum and method the module exports is reached by the Pester suite, and a gate suite fails the run when one is not: 181 tests pass in PowerShell 7.6.6 and Windows PowerShell 5.1 on Windows x64, and in PowerShell 7.6.5 on Ubuntu on Linux x64. Both native libraries ship in the one module folder.
