v1.1.0

Added

• FilteredList<T>: incremental dispatch of source Add/Remove (single and batch), Replace and Move (single) — no full rebuild on every event for the common cases. Reset and batch Replace/Move still fall back to a full Update().
• ObservableList<T>.RemoveRange(int startIndex, int count) and the protected OnRemovedRange(in IReadOnlyList<T>) hook. ObservableListSync<TFrom, TTo> forwards source batch removes through it.
• Batch propagation in ObservableDictionarySync<TKey, TFrom, TTo> and ObservableHashSetSync<TFrom, TTo> for Add / Remove (and Replace on Dictionary) — previously threw NotImplementedException.
• CollectionChangedEvent<T>: re-entrancy-safe via copy-on-write of the subscriber list during Invoke; a lazy HashSet<Handler> tracks unsubscribes during the invoke chain for O(1) skip of removed handlers.
• Performance benchmark scaffold under Tests/Runtime/Observable/Performance/, gated by the ASPID_COLLECTIONS_PERFORMANCE_TESTING define.
• Aspid script icon at Editor/Resources/Icons/aspid_icon_medium_green_1022x1011.png; runtime and test .cs.meta files point to it so scripts surface the project icon in the Unity Project view.
• Samples~/ directory with five importable samples (package.json samples manifest): basic change-notification dispatch, model→view sync via CreateSync, chained FilteredList for search+category, ObservableDictionary as a keyed table, and SplitByEvents as an analytics tap. Each sample ships its own Aspid.Collections.Samples.* asmdef.
• package.json metadata: unityRelease field, a com.unity.test-framework@1.6.0 dependency, and author.url / changelogUrl / documentationUrl / licensesUrl entries.

Changed

• BREAKING — package renamed from com.aspid.collections to tech.aspid.collections. Consumers must update the identifier in their project's Packages/manifest.json (and any scoped-registry / Git-URL references) when upgrading from 1.0.x.
• Tests reorganized under Tests/Runtime/Observable/ to match Unity's standard runtime/editor split. The test assembly is renamed from Aspid.Collections.Observable.Tests to Aspid.Collections.Tests (now with an empty rootNamespace), and the Editor-only includePlatforms constraint is dropped from both the test and performance asmdefs so suites compile and run on player platforms too.
• BREAKING — ASPID_COLLECTIONS_PERFORMANCE_TESTING removed from the performance asmdef's defineConstraints. Without com.unity.test-framework.performance installed the perf asmdef now fails to compile instead of being silently excluded; the define is still auto-set via versionDefines when the package is present.
• ObservableQueueSync / ObservableStackSync / ObservableDictionarySync: unsupported actions now throw NotSupportedException with a descriptive message instead of NotImplementedException.
• Release workflow excludes CLAUDE.md / CLAUDE.md.meta from the published UPM tree (alongside .github).

Fixed

• ObservableStackSync.OnPoppedRange and ObservableQueueSync.OnDequeuedRange overrides recursed into themselves via C# overload resolution, causing StackOverflowException on Dispose and any batch dequeue/pop.
• ObservableDictionarySync.OnReplaced passed newItem.Value to OnRemoved, disposing/notifying the freshly inserted value instead of the discarded one.
• FilteredList.ApplyMoveSingle did not re-seat the moved entry when a Comparer was set; for comparer-equal items the source-index tie-break could drift from a fresh Update() rebuild.
• ObservableHashSetSync.AddOne ignored the Add return value, silently corrupting _sync on a non-injective converter — now throws InvalidOperationException. RemoveOne uses TryGetValue instead of the indexer to avoid KeyNotFoundException inside the source's Invoke.
• ObservableList<T>.RemoveRange validates both startIndex < 0 and count < 0 → ArgumentOutOfRangeException before taking the lock (previously OverflowException from new T[-1] for count, and IndexOutOfRangeException from the per-item read for startIndex).
• FilteredList 3-arg constructor: source subscription now happens after _filter / _comparer are set, closing a subscribe-before-init window.

v1.0.2

Added

• Release workflow that publishes a UPM branch and per-version upm/* tags.

Changed

• README: replaced the Installation section with a UPM-only Integration section.
• Refreshed .meta files.
