There is no transient lifetime, and the README never said what to do instead. The new section, in the Scopes part, says it: a value made fresh on every use is a function, registered like any service under a named function type; the container builds the factory once and never sees what it makes, so the products are the caller's to release or the factory's to pool; and a value that needs a lifecycle of its own is Scoped, resolved from a child scope per unit of work and stopped with it. One line each on samber/do's untracked ProvideTransient and on fx, which has no transient and uses the same function. examples/factory/main.go is the embedded program, run in CI beside the other short examples.

#### Factoriesto the Scopes part, between "Request scopes" and "Groups":ExplainandWirehave a name to show.*sql.Connis, or the factory's to pool.Scoped(), resolved from a child scope per unit of work and stopped with it.ProvideTransientinstances are not tracked either (checked in v2.1.0's source:shutdownandhealthcheckare no-ops), and on fx, which has no transient and uses the same function.examples/factory/main.gois the embedded program, 41 lines, shown open with its output. It is added to the CI list of short examples that are run as well as compiled.Docs only: no CHANGELOG entry. embedmd is in sync, the examples module vets and tests, gofmt is clean.
