2.8

Migrates 2.x branch to AndroidX.

2.0.0

• New architecture distances Picasso further from the main thread using a dedicated dispatcher
  thread to manage requests.
• Request merging. Two requests on the same key will be combined and the result will be delivered
  to both at the same time.
• fetch() requests are now properly wired up to be used as "warm up the cache" type of requests
  without a target.
• fit() will now automatically wait for the view to be measured before executing the request.
• shutdown() API added. Clears the memory cache and stops all threads. Submitting new requests
  will cause a crash after shutdown() has been called.
• Batch completed requests to the main thread to reduce main thread re-layout/draw calls.
• Variable thread count depending on network connectivity. The faster the network the more threads
  and vice versa.
• Ability to specify a callback with ImageView requests.
• Picasso will now decode the bounds of the target bitmap over the network. This helps avoid
  decoding 2000x2000 images meant for 100x100 views.
• Support loading asset URIs in the form file:///android_asset/....
• BETA: Ability to rewrite requests on the fly. This is useful if you want to add custom logic for
  wiring up requests differently.

1.1.1

• Fix: Ensure old requests for targets are cancelled when using a null image.

1.1.0

• load method can now take a Uri.
• Support loading contact photos given a contact Uri.
• Add centerInside() image transformation.
• Fix: Prevent network stream decodes from blocking each other.

1.0.2

• Auto-scale disk cache based on file system size.
• placeholder now accepts null for clearing an existing image when used in an adapter and
  without an explicit placeholder image.
• New global failure listener for reporting load errors to a remote analytics or crash service.
• Fix: Ensure disk cache folder is created before initialization.
• Fix: Only use the built-in disk cache on API 14+ (but you're all using [OkHttp][1] anyways,
  right?).

1.0.1

• Fix: Properly set priority for download threads.
• Fix: Ensure stats thread is always initialized.

1.0.0

Initial release.
