# Revision history for reflex-dom-core
## Unreleased
## 0.5.2
* Update to use new dependent-sum/map packages and drop dependency on `*Tag` classes (e.g., `ShowTag`).
* Update version bounds of base, containers, and stm
* Update to use the newly split `these`/`semialign` packages. To use the pre-split `these` package, set the `split-these` flag to false.
* Reintroduce "data-ssr": elements without this attribute are skipped during
hydration.
* Fix an issue in the hydration tests that prevented the test from finding the chromium executable
* Relax constraints on `dyn` and `widgetHold` to match the ones in `networkView` and `networkHold` respectively
* Fix prerender for RequesterT so that it doesn't accidentally discard a request that is made at the same moment as getPostBuild's Event fires
## 0.5.1
* Added support for marking elements with a "data-skip-hydration" attribute, which will cause hydration to ignore and skip over them.
* Removed "data-ssr" attributes from statically rendered output.
## 0.5
* Add HydrationDomBuilderT to support hydration of statically rendered DOM nodes. See the note at the top of Reflex.Dom.Builder.Immediate.
* As a result of the hydration changes, the Prerender class has changed, the type of `prerender` has changed and it is now a class method.
* Add the Reflex.Dom.Xhr.FormData module to make posting formdata over xhr more convenient.
