+## [2.0.0](https://github.com/TrigenSoftware/nano_kit/compare/v1.2.0...v2.0.0) (2026-09-28)
+
+### ⚠ BREAKING CHANGES
+
+* **store,query:** `$getMapKey`, `setMapKey`, `deleteMapKey`, `clearMap`, `subMapEvent`,
+  `fireMapEvent`, `$$insert`, `$$clear`, `$$deleted` and the `SignalsMapEvent` and
+  `SignalsMapEvents` types are removed from `@nano_kit/store`, and `SignalsMap` is a class to
+  create with `new`, not a type over a plain `Map`. The `cache` of a query client context is
+  a `ShardedSignalsMap`: its `has`, `set` and `delete` take a sharded key.
+* **agera,kida:** `effect` no longer defers when created inside a deferred scope body: use
+  `deferEffect` there. `subscribe`, `listen`, `observe` and `subscribeAny` no longer accept the
+  `noDefer` argument.
+* **kida:** `resolved` hands values through verbatim - a falsy source value is data, not a
+  reset to `undefined`: emptiness is expressed by `T` itself (e.g. `T | null`), and the input type
+  drops the falsy arm.
+* **kida,store:** an operator called with static operands returns the value, not an accessor.
+  `concat` is removed, the `f` tag takes its place.
+* the packages require Node.js 24 or newer.
+* **kida,store,query:** the tasks pool is gone — `TasksPool$`, `TasksRunner$`, `tasksRunner`, `addTask`,
+  `waitCurrentTasks` and `taskPromise` are removed, `waitTasks` takes a signal instead of a pool, and
+  the `tasks()` and `ssr()` query settings are removed: `hydratable()` is the whole SSR setting.
+

+* **kida:** add `latest` for the value of the source that changed last ([#231](https://github.com/TrigenSoftware/nano_kit/issues/231)) ([84efaed](https://github.com/TrigenSoftware/nano_kit/commit/84efaed2453ab10542afad83958fdea2f709c899))

+## [2.0.0](https://github.com/TrigenSoftware/nano_kit/compare/v1.2.0...v2.0.0) (2026-09-28)
+
+### ⚠ BREAKING CHANGES
+
+* `effect` no longer defers when created inside a deferred scope body: use
+  `deferEffect` there. `subscribe`, `listen`, `observe` and `subscribeAny` no longer accept the
+  `noDefer` argument.
+* `resolved` hands values through verbatim - a falsy source value is data, not a
+  reset to `undefined`: emptiness is expressed by `T` itself (e.g. `T | null`), and the input type
+  drops the falsy arm.
+* an operator called with static operands returns the value, not an accessor.
+  `concat` is removed, the `f` tag takes its place.
+* the packages require Node.js 24 or newer.
+* the tasks pool is gone — `TasksPool$`, `TasksRunner$`, `tasksRunner`, `addTask`,
+  `waitCurrentTasks` and `taskPromise` are removed, `waitTasks` takes a signal instead of a pool, and
+  the `tasks()` and `ssr()` query settings are removed: `hydratable()` is the whole SSR setting.
+
+### Features
+
+* add `deferEffect` for effects owned by a deferred scope ([#257](https://github.com/TrigenSoftware/nano_kit/issues/257)) ([12cb14b](https://github.com/TrigenSoftware/nano_kit/commit/12cb14b4ca39645dbd2899e8e2b79738d387c854))
+* add `latest` for the value of the source that changed last ([#231](https://github.com/TrigenSoftware/nano_kit/issues/231)) ([84efaed](https://github.com/TrigenSoftware/nano_kit/commit/84efaed2453ab10542afad83958fdea2f709c899))
+* add `uninspected` to keep the nodes of a listener out of `inspect`, and the old value to `UpdateEvent` ([#262](https://github.com/TrigenSoftware/nano_kit/issues/262)) ([83384ce](https://github.com/TrigenSoftware/nano_kit/commit/83384ce8e61f37d27bf8989df91c503f0ec3200e))
+* add development diagnostics with separate development and production builds ([#236](https://github.com/TrigenSoftware/nano_kit/issues/236)) ([39be996](https://github.com/TrigenSoftware/nano_kit/commit/39be99600aa5c5066b8eb5205431740986df3dee))
+* attach tasks to the signals they fill ([#222](https://github.com/TrigenSoftware/nano_kit/issues/222)) ([841acd1](https://github.com/TrigenSoftware/nano_kit/commit/841acd12fcb3c2bd6c494f9ff47dfe998c962457))
+* attach the `resolved` promise as a task and hand values through verbatim ([#223](https://github.com/TrigenSoftware/nano_kit/issues/223)) ([8fabbeb](https://github.com/TrigenSoftware/nano_kit/commit/8fabbeb80f6462ac32c90a8b1ac523c8086971e7))
+* export `child` to build custom child signals ([#250](https://github.com/TrigenSoftware/nano_kit/issues/250)) ([8794697](https://github.com/TrigenSoftware/nano_kit/commit/8794697145e338684cf90e91fc6ceb81eb4e9adb))
+* rename the template tag `f` to `text` ([505d947](https://github.com/TrigenSoftware/nano_kit/commit/505d9479b4d75b4008d11718606392322cec1e89))
+* require Node.js 24 ([#268](https://github.com/TrigenSoftware/nano_kit/issues/268)) ([c6ed062](https://github.com/TrigenSoftware/nano_kit/commit/c6ed0627e0e76785941ede1bb8f280c5d80896a0))
+* return a plain result from the operators when every operand is static ([#260](https://github.com/TrigenSoftware/nano_kit/issues/260)) ([3a8b32f](https://github.com/TrigenSoftware/nano_kit/commit/3a8b32f674e045cc42fd422803983f604b5cb4f9))
+
+### Bug Fixes
+
+* keep `onMount` subscribed when a signal remounts within the unmount delay ([#229](https://github.com/TrigenSoftware/nano_kit/issues/229)) ([b911d4c](https://github.com/TrigenSoftware/nano_kit/commit/b911d4ce7657e67e47427f4863e0ab4b90212949))

+## [2.0.0](https://github.com/TrigenSoftware/nano_kit/compare/v1.2.0...v2.0.0) (2026-09-28)
+
+### ⚠ BREAKING CHANGES
+
+* `$getMapKey`, `setMapKey`, `deleteMapKey`, `clearMap`, `subMapEvent`,
+  `fireMapEvent`, `$$insert`, `$$clear`, `$$deleted` and the `SignalsMapEvent` and
+  `SignalsMapEvents` types are removed from `@nano_kit/store`, and `SignalsMap` is a class to
+  create with `new`, not a type over a plain `Map`. The `cache` of a query client context is
+  a `ShardedSignalsMap`: its `has`, `set` and `delete` take a sharded key.
+* an operator called with static operands returns the value, not an accessor.
+  `concat` is removed, the `f` tag takes its place.
+* the packages require Node.js 24 or newer.
+* the tasks pool is gone — `TasksPool$`, `TasksRunner$`, `tasksRunner`, `addTask`,
+  `waitCurrentTasks` and `taskPromise` are removed, `waitTasks` takes a signal instead of a pool, and
+  the `tasks()` and `ssr()` query settings are removed: `hydratable()` is the whole SSR setting.
+
+### Features
+
+* add `uninspected` to keep the nodes of a listener out of `inspect`, and the old value to `UpdateEvent` ([#262](https://github.com/TrigenSoftware/nano_kit/issues/262)) ([83384ce](https://github.com/TrigenSoftware/nano_kit/commit/83384ce8e61f37d27bf8989df91c503f0ec3200e))
+* add development diagnostics with separate development and production builds ([#236](https://github.com/TrigenSoftware/nano_kit/issues/236)) ([39be996](https://github.com/TrigenSoftware/nano_kit/commit/39be99600aa5c5066b8eb5205431740986df3dee))
+* add the DevTools panel ([#263](https://github.com/TrigenSoftware/nano_kit/issues/263)) ([bc1e51a](https://github.com/TrigenSoftware/nano_kit/commit/bc1e51a9c8e5979aa7813039c4e78bfd052bccc0))
+* attach tasks to the signals they fill ([#222](https://github.com/TrigenSoftware/nano_kit/issues/222)) ([841acd1](https://github.com/TrigenSoftware/nano_kit/commit/841acd12fcb3c2bd6c494f9ff47dfe998c962457))
+* replace the signals map functions with the `SignalsMap` and `IndexedSignalsMap` classes ([#261](https://github.com/TrigenSoftware/nano_kit/issues/261)) ([c062f06](https://github.com/TrigenSoftware/nano_kit/commit/c062f068a65f3869ec907175f0e1cc14e96d54a8))

+* return a plain result from the operators when every operand is static ([#260](https://github.com/TrigenSoftware/nano_kit/issues/260)) ([3a8b32f](https://github.com/TrigenSoftware/nano_kit/commit/3a8b32f674e045cc42fd422803983f604b5cb4f9))
