2.1.1 (November 11, 2022)

• Fix create resource concurrently with Stat call race

2.1.0 (October 28, 2022)

• Concurrency control is now implemented with a semaphore. This simplifies some internal logic, resolves a few error conditions (including a deadlock), and improves performance. (Jan Dubsky)
• Go 1.19 is now required for the improved atomic support.

2.0.1 (October 28, 2022)

• Fix race condition when Close is called concurrently with multiple constructors

2.0.0 (September 17, 2022)

• Use generics instead of interface{} (Столяров Владимир Алексеевич)
• Add Reset
• Do not cancel resource construction when Acquire is canceled
• NewPool takes Config

1.3.0 (August 27, 2022)

• Acquire creates resources in background to allow creation to continue after Acquire is canceled (James Hartig)

1.2.1 (December 2, 2021)

• TryAcquire now does not block when background constructing resource

1.2.0 (November 20, 2021)

• Add TryAcquire (A. Jensen)
• Fix: remove memory leak / unintentionally pinned memory when shrinking slices (Alexander Staubo)
• Fix: Do not leave pool locked after panic from nil context

1.1.4 (September 11, 2021)

• Fix: Deadlock in CreateResource if pool was closed during resource acquisition (Dmitriy Matrenichev)

1.1.3 (December 3, 2020)

• Fix: Failed resource creation could cause concurrent Acquire to hang. (Evgeny Vanslov)

1.1.2 (September 26, 2020)

• Fix: Resource.Destroy no longer removes itself from the pool before its destructor has completed.
• Fix: Prevent crash when pool is closed while resource is being created.

1.1.1 (April 2, 2020)

• Pool.Close can be safely called multiple times
• AcquireAllIDle immediately returns nil if pool is closed
• CreateResource checks if pool is closed before taking any action
• Fix potential race condition when CreateResource and Close are called concurrently. CreateResource now checks if pool is closed before adding newly created resource to pool.

1.1.0 (February 5, 2020)

• Use runtime.nanotime for faster tracking of acquire time and last usage time.
• Track resource idle time to enable client health check logic. (Patrick Ellul)
• Add CreateResource to construct a new resource without acquiring it. (Patrick Ellul)
• Fix deadlock race when acquire is cancelled. (Michael Tharp)
