-## Usage
-
-Use TypeScript for best in class instellisense.
-
-```javascript
-// import any tool that you need from lik
-import { Stringmap, Objectmap, Observablemap } from 'lik';
-```
-
-### class Stringmap
-
-Stringmap allows you to keep track of strings. It allows you to register triggers for certain events
-like when a certain string is removed or added to the map
-
-### class Objectmap
-
-Sometimes you need to keep track of objects, but implementing logic for removing, finding or updating is tedious.
-Objectmap takes care of keeping track of objects for you.

+# Changelog
+
+## 2026-03-01 - 6.3.1 - fix(classes)
+cleanup resources, add cancellable timeouts, and fix bugs in several core utility classes
+
+- Replace one-shot delayFor usage with plugins.smartdelay.Timeout in AsyncExecutionStack so timeouts are cancellable and properly cleaned up on success or error
+- Add destroy() to BackpressuredArray to complete subjects and unblock waiters; waitForSpace/waitForItems now respect destruction to avoid hangs
+- Make Interest instances cancel mark-lost timers and guard against double-destroy; destruction now clears fulfillment store and resolves default fulfillment without mutual recursion
+- Add InterestMap.destroy() to clean up all interests and complete observable
+- ObjectMap: removeMappedUnique now returns removed object and emits a remove event; wipe now emits remove events for cleared entries and destroy() completes eventSubject
+- StringMap.destroy() clears stored strings and pending triggers
+- TimedAggregtor: add stop(flushRemaining) and isStopped guards to stop timer chain and optionally flush remaining items
+- LoopTracker: add reset() and destroy() helpers to clear and destroy internal maps
+- Fix compareTreePosition to call symbolTree.compareTreePosition instead of recursively calling itself
+
+## 2026-03-01 - 6.3.0 - feat(tooling)
+update build tooling, developer dependencies, npmextra configuration, and expand README documentation
+
+- Bump devDependencies for @git.zone toolchain and related packages (@git.zone/tsbuild, tsbundle, tsrun, tstest, @push.rocks/tapbundle, @types/node)
+- Bump runtime deps: @push.rocks/smartrx and @push.rocks/smarttime
+- Adjust npm build script: remove trailing 'npm' argument from tsbundle invocation
+- Rework npmextra.json: rename/unify keys to @git.zone/* scoped entries, add release registries and accessLevel, add tsbundle bundle configuration, and reorganize CI/tool settings
+- Significant README rewrite: expanded descriptions, clearer usage examples and API snippets, formatting and example updates
+
+## 2026-03-01 - 6.2.3 - fix(interestmap)
+remove interest from InterestMap immediately after fulfillment
+
+- Call destroy() in fullfillInterest to remove the interest entry from the InterestMap right after resolving interestDeferred.
+- Prevents stale entries and ensures immediate cleanup of fulfilled interests
+
+## 2025-04-25 - 6.2.2 - fix(docs)
+Update @push.rocks/tapbundle dependency and refine AsyncExecutionStack documentation examples
+
+- Bump @push.rocks/tapbundle from ^5.0.8 to ^5.5.6 in package.json
+- Improve README documentation for AsyncExecutionStack with clearer examples for exclusive and non-exclusive task execution
+- Demonstrate usage of concurrency controls in AsyncExecutionStack
+
+## 2025-04-25 - 6.2.1 - fix(AsyncExecutionStack tests)
+Refactor AsyncExecutionStack tests: update non-exclusive concurrency assertions and clean up test logic
+
+- Replace 'toBe' with 'toEqual' for active and pending counts to ensure consistency
+- Simplify default non-exclusive concurrency test by asserting Infinity is non-finite using toBeFalse
+- Adjust test comments and scheduling for clarity in concurrency behavior
+
+## 2025-04-25 - 6.2.0 - feat(AsyncExecutionStack)
+Improve non-exclusive task management with concurrency limit controls and enhanced monitoring in AsyncExecutionStack.
+
+- Added methods to set and get non-exclusive concurrency limits and statistics (setNonExclusiveMaxConcurrency, getActiveNonExclusiveCount, getPendingNonExclusiveCount, and getNonExclusiveMaxConcurrency).
+- Integrated proper waiting and release mechanisms for non-exclusive slots.
+- Extended test coverage to validate concurrency limits and ensure correct behavior.
+
+## 2024-10-13 - 6.1.0 - feat(BackpressuredArray)
+Add method to check if items are present in BackpressuredArray
+
+- Implemented a new method `checkHasItems` in the BackpressuredArray class to determine if the array contains any items.

+# @push.rocks/lik
+
+A collection of lightweight utility classes for TypeScript/Node.js projects, providing efficient data structures and async helpers.
+
+## Install
+
+```bash
+npm install @push.rocks/lik
+```
+
+## Usage
+
+`@push.rocks/lik` provides a set of focused helper classes for common programming tasks: managing collections, controlling async execution, tracking interests, and more. All classes are fully typed and work in both Node.js and browser environments.
+
+### AsyncExecutionStack
+
+Controls execution of asynchronous tasks in two modes:
+
+- **Exclusive**: tasks run one at a time, blocking all others until complete.
+- **Non-exclusive**: tasks run in parallel with optional concurrency limits.
+
+```typescript
+import { AsyncExecutionStack } from '@push.rocks/lik';
+
+const stack = new AsyncExecutionStack();
+
+// Exclusive execution (sequential, blocks other tasks)
+await stack.getExclusiveExecutionSlot(async () => {
+  // critical section work
+}, 5000); // optional timeout in ms
+
+// Non-exclusive execution (parallel)
+const p1 = stack.getNonExclusiveExecutionSlot(async () => {
+  // concurrent work 1
+});
+const p2 = stack.getNonExclusiveExecutionSlot(async () => {
+  // concurrent work 2
+});
+await Promise.all([p1, p2]);
+
+// Control concurrency
+stack.setNonExclusiveMaxConcurrency(3);
+console.log(stack.getNonExclusiveMaxConcurrency()); // 3
+console.log(stack.getActiveNonExclusiveCount());    // currently running
+console.log(stack.getPendingNonExclusiveCount());   // waiting for slots
+```
+
+### BackpressuredArray
+
+An array with backpressure support using RxJS subjects. Useful for producer/consumer patterns where you need to throttle the producer when the consumer can't keep up.
+
+```typescript
+import { BackpressuredArray } from '@push.rocks/lik';
+
+const buffer = new BackpressuredArray<string>(16); // high water mark of 16
+
+// Producer: push items, returns false when full
+const hasSpace = buffer.push('item1');
+if (!hasSpace) {
+  await buffer.waitForSpace(); // wait until consumer frees space
+}
+
+// Consumer: shift items out
+await buffer.waitForItems(); // wait until items are available
+const item = buffer.shift();
+
+// Check state
+buffer.checkSpaceAvailable(); // true if below high water mark
+buffer.checkHasItems();       // true if items exist
+```
+
+### FastMap
+
+A high-performance key-value map optimized for rapid lookups and modifications.
+
+```typescript
+import { FastMap } from '@push.rocks/lik';
+
+const map = new FastMap<string>();
+
+map.addToMap('key1', 'value1');
+map.addToMap('key2', 'value2');
+
+const value = map.getByKey('key1'); // 'value1'
+map.isUniqueKey('key1');            // false (already exists)
+map.removeFromMap('key1');
+
+// Merge maps
+const otherMap = new FastMap<string>();
+otherMap.addToMap('key3', 'value3');
+const merged = map.concat(otherMap);
+
+// Or merge in place
+map.addAllFromOther(otherMap);
+
+// Async find
+const found = await map.find(async (item) => item === 'value2');
+```
+
+### InterestMap
+
+Manages subscriptions/interests in events or entities. Multiple parties can express interest in the same thing; the interest is deduplicated and fulfilled once.
+
+```typescript
+import { InterestMap } from '@push.rocks/lik';
+
+const interestMap = new InterestMap<string, number>(
+  (str) => str, // comparison function to deduplicate interests
+  { markLostAfterDefault: 30000 } // optional: auto-mark lost after 30s
+);
+
+// Express interest
+const interest = await interestMap.addInterest('event1');
+
+// Wait for fulfillment
+interest.interestFullfilled.then((result) => {
+  console.log('Got result:', result);
+});
+
+// Fulfill from elsewhere
+const found = interestMap.findInterest('event1');
+found.fullfillInterest(42);
+
+// Check and manage interests
+interestMap.checkInterest('event1'); // true/false
+interestMap.informLostInterest('event1'); // starts destruction timer
+
+// Observable stream of new interests
+interestMap.interestObservable; // ObservableIntake<Interest>
+```
+
+### LimitedArray
+
+An array that automatically enforces a maximum size, discarding oldest items when the limit is exceeded.
+
+```typescript
+import { LimitedArray } from '@push.rocks/lik';
+
+const arr = new LimitedArray<number>(5);
+
+arr.addMany([1, 2, 3, 4, 5, 6]);
+console.log(arr.array.length); // 5 (oldest items dropped)
+
+arr.addOne(7);
+arr.setLimit(3); // dynamically adjust limit
+
+// Compute average (for numeric arrays)
+const numArr = new LimitedArray<number>(10);
+numArr.addMany([10, 20, 30]);
+console.log(numArr.getAverage()); // 20
+```
+
+### LoopTracker
+
+Detects and prevents infinite loops by tracking object references during iterations.
+
+```typescript
+import { LoopTracker } from '@push.rocks/lik';
+
+const tracker = new LoopTracker<object>();
+const obj1 = {};
+
+tracker.checkAndTrack(obj1); // true (first time, tracked)
+tracker.checkAndTrack(obj1); // false (already seen - loop detected!)
+```
+
+### ObjectMap
+
+A managed collection of objects with add/remove/find operations and event notifications via RxJS.
+
+```typescript
+import { ObjectMap } from '@push.rocks/lik';
+
+interface IUser {
+  id: number;
+  name: string;
+}
+
+const users = new ObjectMap<IUser>();
+
+// Add objects
+const key = users.add({ id: 1, name: 'Alice' });
+users.addArray([{ id: 2, name: 'Bob' }, { id: 3, name: 'Carol' }]);
+
+// Find objects
+const alice = users.findSync((u) => u.id === 1);
+const bob = await users.find(async (u) => u.id === 2);
+
+// Find and remove in one step
+const removed = await users.findOneAndRemove(async (u) => u.id === 3);
+const removedSync = users.findOneAndRemoveSync((u) => u.id === 2);
+
+// Direct add/get by unique key
+users.addMappedUnique('admin', { id: 99, name: 'Admin' });
+const admin = users.getMappedUnique('admin');
+
+// Get one and remove (FIFO-style)
+const first = users.getOneAndRemove();
+
+// Iterate, check, and manage
+await users.forEach((u) => console.log(u.name));
+users.checkForObject(alice);  // true/false
+users.isEmpty();               // true/false
+users.getArray();              // cloned array of all objects
+users.wipe();                  // remove all
+
+// Listen for changes
+users.eventSubject.subscribe((event) => {
+  console.log(event.operation, event.payload); // 'add' | 'remove'
+});
+
+// Merge object maps
+const merged = users.concat(otherObjectMap);
+users.addAllFromOther(otherObjectMap);
+```
+
+### Stringmap
+
+Manages a collection of strings with add/remove/query operations and minimatch pattern matching.
+
+```typescript
+import { Stringmap } from '@push.rocks/lik';
+
+const strings = new Stringmap();
+
+strings.addString('hello');
+strings.addStringArray(['world', 'example']);
+
+strings.checkString('hello');       // true
+strings.checkMinimatch('hel*');     // true (glob matching)
+strings.checkIsEmpty();             // false
+
+strings.removeString('hello');
+strings.getStringArray();           // ['world', 'example']
+
+// Register trigger that fires when condition is met
+await strings.registerUntilTrue((arr) => arr.length === 0);
+strings.wipe(); // triggers the above
+```
+
+### TimedAggregator
+
+Batches items over a time interval, then processes them in bulk. Useful for aggregating logs, metrics, or events.
+
+```typescript
+import { TimedAggregtor } from '@push.rocks/lik';
+
+const aggregator = new TimedAggregtor<string>({
+  aggregationIntervalInMillis: 5000,
+  functionForAggregation: (items) => {
+    console.log('Batch:', items);
+  },
+});
+
+aggregator.add('event1');
+aggregator.add('event2');
+// After 5 seconds: Batch: ['event1', 'event2']
+```
+
+### Tree
+
+A typed wrapper around `symbol-tree` for managing hierarchical data structures with parent/child/sibling relationships.
+
+```typescript
+import { Tree } from '@push.rocks/lik';
+
+class TreeNode {
+  constructor(public value: string) {}
+}
+
+const tree = new Tree<TreeNode>();
+const root = new TreeNode('root');
+tree.initialize(root);
+
+const child1 = new TreeNode('child1');
+const child2 = new TreeNode('child2');
+tree.appendChild(root, child1);
+tree.appendChild(root, child2);
+
+// Navigate
+tree.hasChildren(root);        // true
+tree.firstChild(root);         // child1
+tree.lastChild(root);          // child2
+tree.nextSibling(child1);     // child2
+tree.parent(child1);           // root
+
+// Query
+tree.childrenCount(root);     // 2
+tree.index(child2);           // 1
+tree.childrenToArray(root, {}); // [child1, child2]
+tree.treeToArray(root, {});     // full tree as array
+
+// Mutate
+tree.insertBefore(child2, new TreeNode('between'));
+tree.remove(child2);
+```
