It appears compose will call onRemembered multiple times without an onForgotten call in between. Previously that would cause GlidePainter to launch multiple requests. These requests are deduplicated by Glide, so only one image is loaded. However there's still additional wasted work and churn from tracking the additional request. To avoid launching the duplicate request, we track the current job in onRemembered, then cancel and null it out in onForgotten. If onRemembered is called again and there's an active job, we can just ignore the new call to onRemembered. Fixes bumptech#5032

The two major Compose improvements are adding support for Compose specific transitions (e.g. cross fade) and supporting recomposition based on request state using `GlideSubcomposition`. There's also been a bunch of internal refactoring to move away from Painters to Modifier nodes based on feedback from the Compose team. This is still an alpha release of Compose, but barring unexpectedly negative feedback, the next release should be beta. This should be the last release of Glide that targets Java 7. That probably means our next release will be a major version change. ##### Features - Allow passing an executor into ChromiumRequestSerializer in [https://github.com/bumptech/glide/pull/5077](https://togithub.com/bumptech/glide/pull/5077) - Allow host app to provide a way to clear all resources onStop() by [@​osamaaftab](https://togithub.com/osamaaftab) in [https://github.com/bumptech/glide/pull/5145](https://togithub.com/bumptech/glide/pull/5145) ##### Compose - Add a Transition API and a CrossFade Transition for Compose by [@​sjudd](https://togithub.com/sjudd) in [https://github.com/bumptech/glide/pull/5235](https://togithub.com/bumptech/glide/pull/5235) - Influence layout using intrinsics in GlideNode by [@​sjudd](https://togithub.com/sjudd) in [https://github.com/bumptech/glide/pull/5240](https://togithub.com/bumptech/glide/pull/5240) \* Log instead of throwing parsing manifests to fix compose previews by [@​sjudd](https://togithub.com/sjudd) in [https://github.com/bumptech/glide/pull/5167](https://togithub.com/bumptech/glide/pull/5167) - Launch no more than one request per onRemembered by [@​sjudd](https://togithub.com/sjudd) in [https://github.com/bumptech/glide/pull/5062](https://togithub.com/bumptech/glide/pull/5062) - Remove GlidePainter in favor of Modifier nodes / Flows by [@​sjudd](https://togithub.com/sjudd) in [https://github.com/bumptech/glide/pull/5230](https://togithub.com/bumptech/glide/pull/5230) - Replace flows in GlideSubcomposition with a listener on GlideNode by [@​sjudd](https://togithub.com/sjudd) in [https://github.com/bumptech/glide/pull/5238](https://togithub.com/bumptech/glide/pull/5238) ##### Bugs - Read library glide module names from Java indexes by [@​sjudd](https://togithub.com/sjudd) in [https://github.com/bumptech/glide/pull/5052](https://togithub.com/bumptech/glide/pull/5052) - Fix typo. anay -> any in GlideSymbolProcessor.kt. by [@​trevorhackman](https://togithub.com/trevorhackman) in [https://github.com/bumptech/glide/pull/5029](https://togithub.com/bumptech/glide/pull/5029) - Include URL in error log by [@​paulsowden](https://togithub.com/paulsowden) in [https://github.com/bumptech/glide/pull/5164](https://togithub.com/bumptech/glide/pull/5164) - Add `isInitialized` visible for testing method by [@​paulsowden](https://togithub.com/paulsowden) in [https://github.com/bumptech/glide/pull/5163](https://togithub.com/bumptech/glide/pull/5163) - Use onIdle to avoid a race in FlowTests by [@​sjudd](https://togithub.com/sjudd) in [https://github.com/bumptech/glide/pull/5202](https://togithub.com/bumptech/glide/pull/5202) - Add a isEquivalentTo method to correctly check equality by [@​mori-atsushi](https://togithub.com/mori-atsushi) in [https://github.com/bumptech/glide/pull/5232](https://togithub.com/bumptech/glide/pull/5232) - Add [@​RequiresPermission](https://togithub.com/RequiresPermission) to NotificationTarget by [@​TWiStErRob](https://togithub.com/TWiStErRob) in [https://github.com/bumptech/glide/pull/5220](https://togithub.com/bumptech/glide/pull/5220) ##### Deprecations - `placeholderOf(@​Composable)` in `GlideImage` is deprecated, use `GlideSubcomposition` instead.
