9.0.7

Fixes:

• 76fd915 Fixed that ChangeSet was incorrectly counting item changes, by not including Refresh changes, and added corresponding tests. (reactivemarbles#892) @JakenVeina
• 903afc8 Fixed ambiguous overloads for ObservableCacheEx.ExpireAfter() and ObservableListEx.ExpireAfter(). (reactivemarbles#822) @JakenVeina
• 897beb8 fix polyfills visibility (reactivemarbles#910) @kronic
• 41a608d Fixed premature evaluation of the collection within the Cache TrueFor operators, causing premature and potentially incorrect emissions to occur, when items in the collection publish values immediately upon subscription. (reactivemarbles#923) @JakenVeina
• afbbb47 Fixed a bogus use of the default keyword, within a ternary expression where implicit casting of a generic is in play. The expression compiles differently depending on whether the generic type in question is a value type, versus a reference type, and generates an excpetion in the case of a value type. (reactivemarbles#926) @JakenVeina
• b6e851e Fixed that .Bind() operators for ISortedChangeSet<TObject, TKey> streams were not properly recognizing the ResetOnFirstTimeLoad option. The option was only being used if the initial changeset also exceeded the ResetThreshold setting. (reactivemarbles#935) @JakenVeina
• 2c32489 Fix for GroupOnObservable OnCompleted handling (reactivemarbles#938) @dwcullop
