 # Changelog
 
+## 0.4.31
+
+* `Versions`:
+    * `Kotlin`: `1.4.31` -> `1.4.32`
+* `Pagination`:
+    * New extensions `PaginationResult.changeResultsUnchecked` and `PaginationResult.changeResults` for mapping results
+    with the same parameters, but different data
+    * Extension `PaginationResult.thisPageIfNotEmpty` now is typed and will return `PaginationResult?` with the same
+    generic type as income `PaginationResult`
+    * New extension `PaginationResult.currentPageIfNotEmpty` - shortcut for `PaginationResult.thisPageIfNotEmpty`

-# MicroUtils
+# MicroUtils
+
+This is a library with collection of tools for working in Kotlin environment. First of all, this library collection is oriented to use next technologies:
+
+* [`Kotlin Coroutines`](https://github.com/Kotlin/kotlinx.coroutines)
+* [`Kotlin Serialization`](https://github.com/Kotlin/kotlinx.serialization)
+* [`Kotlin Exposed`](https://github.com/JetBrains/Exposed)
+* [`Ktor`](https://ktor.io)
+
+<details>
+  <summary> <b>Android environment</b> </summary>
+
+You always can look at the <a href="https://github.com/InsanusMokrassar/MicroUtils/blob/master/gradle.properties#L24-L34">properties file</a> to get information about current project dependencies, compile and build tools for `Android` target.
+
+</details>
+
+## Projects
+
+* `common` contains common tools for platform which usually are absent out-of-the-box when you starting project
+* `selector` contains tools to use `Selector` interface with things like `RecyclerView` in android or other selection needs
+* `coroutines` is a module for `Kotlin Coroutines` with different things like subscribing on flows (`onEach` + `launchIn` shortcut :) )
+* `ktor` is a set of modules for `client`s and `server`s
+* `mime_types` is NOT lightweight set of `MimeType`s with a lot of different objected and serializable (with `Kotlin Serialization`) mime types
+* `pagination` is a complex of modules (explanation in [Complex modules structure](#complex-modules-structure) section) for lightweight pagination
+* `serialization` is a collection of projects with serializers for `kotlinx.serialization`
+* `repos` is a complex of modules (explanation in [Complex modules structure](#complex-modules-structure) section) for `KeyValue`/`OneToMany`/`CRUD` repos created to be able to exclude some heavy dependencies when you need some simple and lightweight typical repositories
+
+## Complex modules structure
+
+Most of complex modules are built with next hierarchy:
+
+* `common` submodule for `API` things which are common for all platforms
+* `exposed` submodule contains realizations for exposed tables
+* `ktor` submodule is usually unavailable directly, because it contains its own submodules for clients and servers
+    * `common` part contains routes which are common for clients and servers
+    * `client` submodule contains clients which are usually using `UnifiedRequester` to make requests using routes from `ktor/common` module and some internal logic of requests
+    * `server` submodule (in most cases `JVM`-only) contains some extensions for `Route` instances which usually will give opportunity to proxy internet requests from `ktor/client` realization to some proxy object
