+# 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.
+
+## 2024-05-29 to 2024-04-18 - 6.0.15
+Minor updates were made to documentation and descriptions.
+

 ## Usage
 
-Use TypeScript for best in class instellisense.
+`@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.
 
-```javascript
+### AsyncExecutionStack
-// import any tool that you need from lik
+
-import { Stringmap, Objectmap, Observablemap } from 'lik';
+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
 ```
 
-### class Stringmap
+### BackpressuredArray
 
-Stringmap allows you to keep track of strings. It allows you to register triggers for certain events
+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.
-like when a certain string is removed or added to the map
 
-### class Objectmap
+```typescript
+import { BackpressuredArray } from '@push.rocks/lik';
 
-Sometimes you need to keep track of objects, but implementing logic for removing, finding or updating is tedious.
+const buffer = new BackpressuredArray<string>(16); // high water mark of 16
-Objectmap takes care of keeping track of objects for you.
 
-## Contribution
+// Producer: push items, returns false when full
+const hasSpace = buffer.push('item1');
+if (!hasSpace) {
+  await buffer.waitForSpace(); // wait until consumer frees space
+}
 
-We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
+// Consumer: shift items out
+await buffer.waitForItems(); // wait until items are available
+const item = buffer.shift();
 
-For further information read the linked docs at the top of this readme.
+// Check state
+buffer.checkSpaceAvailable(); // true if below high water mark
+buffer.checkHasItems();       // true if items exist
+```

+### FastMap
-| By using this npm module you agree to our [privacy policy](https://lossless.gmbH/privacy)
 
-[![repo-footer](https://lossless.gitlab.io/publicrelations/repofooter.svg)](https://maintainedby.lossless.com)
+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);
+```
