# Changelog ## 0.6.1 (10.3.2017) **[compare](https://github.com/reagent-project/reagent/compare/v0.6.0...v0.6.1)** - Fix :ref on inputs ([#259](https://github.com/reagent-project/reagent/issues/259)) - React updated to 15.4.0 ([#275](https://github.com/reagent-project/reagent/issues/275), [#276](https://github.com/reagent-project/reagent/issues/276)) - **BREAKING:** `reagent.core` no longer provides `render-to-string` or `render-to-static-markup` functions - `reagent.dom.server` includes the same functions - This is due to change in React packaging, including React-dom-server would increase the file size considerably, so now it is only included when `reagent.dom.server` is used ## 0.6.0 - React updated to 15.2.1 - Fix input on-change events in IE11 ## 0.6.0-rc - React updated to 15.1.0 - Symbols and keywords are now allowed in Hiccup content. They are converted using `name`. - Any object hat satisfies IPrintWithWriter is also allowed, and is converted using `pr-str`. - Bug fixes, improved error handling/reporting, and lots of testing. ## 0.6.0-alpha ### Breaking changes - Reagent now depends on `cljsjs/react-dom` and `cljsjs/react-dom-server`, rather than on `cljsjs/react` directly. - Reactions are now asynchronous, just like Reagent components. `flush` forces outstanding reactions to run. - Reactions now only trigger updates of dependent components if their value change, as reported by `=` (previously, `identical?` was used). - The macros `.'` and `.!` in `reagent.interop` have been renamed to `$` and `$!` respectively. ### News - React updated to 0.14.3 - Added `reagent.dom` and `reagent.dom.server` namespaces, corresponding to new React packages. - `create-class` now returns a normal React class, that can be used directly from javascript. - Add `track`: turns a function call into a reactive value. - Add `track!`: eager version of `track`. - Add `dispose!`: stop the derefable returned by `track!` from updating. - Add `with-let` macro: simpler handling of lifecycle in components and reactions. - Add `rswap!`: works like `swap!`, except that recursive calls are allowed, and they always return nil. - `cursor` now shares state between all instances corresponding to a given set of parameters. - `next-tick` now evokes its argument function at a clearly defined time (immediately before rendering, which is in turn triggered using requestAnimationFrame). - `after-update` is a new function, similar to `next-tick`, except that the function is evoked immediately after rendering. - Support `[:> nativeComp {:foo "bar"}]` - Reagent now falls back to using `require` if global `React` is undefined, to simplify use with e.g webpack and node.js. ## 0.5.1 - React updated to 0.13.3 - Deprecate calling the result of `create-class` as a function (i.e always use hiccup forms to call Reagent components). - Hiccup syntax has been extended to allow nested elements to be defined using '>' as part of the keyword name. - Add `force-update` for completeness. - Try harder to maintain cursor position in inputs. - Simplify examples, taking advantage of new figwheel. - Better warnings and error messages. ## 0.5.0 - React updated to 0.12.2 - Reagent no longer bundles React. Instead it uses cljsjs/react as a dependency. This means that you should no longer specify React in `:preamble` in your project.clj. - ClojureScript 0.0-2816 or later is required. - `adapt-react-class` makes it easier to use "native" React components with Reagent. - `reactify-component` makes it easier to use Reagent components in JSX. - `cursor` is re-written, to be more efficient and flexible. - `render` now forces a deep update of all components, to make it more convenient to use with e.g. figwheel. - Renamed `as-component` to `as-element`, to match React's new terminology better (old name still works, though, for backward compatiblity). - Stop wrapping native components. This reduces the number of components created a lot, and can speed up some things substantially (especially render-to-string, that is not bound by browser performance). This is made possible by a new way of keeping track of which order to re-render dirty components. - Added `create-element` to make it easier to embed native React components in Reagent ones. - Arguments to components are now compared using simple `=`, instead of the old, rather complicated heuristics. **NOTE**: This means all arguments to a component function must be comparable with `=` (which means that they cannot be for example infinite `seq`s). - Reagent now creates all React components using `React.createElement` (required for React 0.12). - `render-component` is now render, and `render-component-to-string` is `render-to-string`, in order to match React 0.12 (but the old names still work). - Add `render-to-static-markup`. This works exactly like `render-to-string`, except that it doesn't produce `data-react-id` etc. - `create-class` now takes a Reagent-style render function (i.e with the same arguments you pass to the component), called `:reagent-render`. ## 0.4.3 - React updated to 0.11.2 - Add reagent.core/cursor - Add javascript interop macros .' and .! - Add force-update-all to make LightTable integration easier - Some performance optimizations ## 0.4.2 - Allow multi-methods as component functions. - Tweak performance by avoiding `clojure.core/memoize`. - Bugfix: Allow on-change handler on controlled inputs to keep value unchanged. ## 0.4.1 - Made Reagent compatible with ClojureScript 0.0-2173. `reagent.core/atom` now implements the necessary IAtom, ISwap and IReset protocols. Reagent should still be compatible with older ClojureScript versions, but you will get a lot of compilation warnings. ## 0.4.0 - Breaking change: Component functions can get arbitrary arguments, and not just vectors and maps. This is a breaking change, but behaviour is unchanged if you pass a map as the first argument (as in all the examples in the old documentation). - React updated to 0.9.0. - You can now use any object that satisfies `ifn?` as a component function, and not just plain functions. That includes functions defined with deftype, defrecord, etc, as well as collections like maps. - `reagent.core/set-state` and `reagent.core/replace-state` are now implemented using a `reagent.core/atom`, and are consequently async. - Keys associated with items in a seq (e.g ”dynamic children” in React parlance) can now be specified with meta-data, as well as with a `:key` item in the first parameter as before. In other words, these two forms are now equivalent: `^{:key foo} [:li bar]` and `[:li {:key foo} bar]`. - Performance has been improved. For example, there is now practically no overhead for tracking derefs in components that don’t use atoms. Allocations and memory use have also been reduced. - Intro and examples have been tweaked a little to take advantage of the new calling conventions. ## 0.3.0 - Changes in application state are now rendered asynchronously, using requestAnimationFrame. - Reagent now does proper batching of updates corresponding to changed atoms, i.e parents are rendered before children, and children are only re-rendered once. - Add `reagent.core/flush` to render changes immediately. - Bugfix: Allow dynamic id with hiccup-style class names. ## 0.2.1 - Bugfix: allow data-* and aria-* attributes to be passed through unchanged. ## 0.2.0 - Rename Cloact to Reagent, due to popular disgust with the old name...
