3.4.0 release notes:

Possible compatibility issues

• Components now use microtasks to perform updates asynchronously instead of setTimeout. Since microtasks are run before the browser repaints the page, all loaded components will be initialized and displayed in a single repaint. Although this reduces the overall time needed to display components, it could result in a longer delay before anything is displayed.
• The new, native deferred updates feature has a slightly different API and is implemented differently than the Deferred Updates plugin. Migrating from the plugin will generally require some code changes (full details to come soon).
• ko.observable and ko.computed no longer use a closure when defining their methods, such as dispose and valueHasMutated. These functions expect this to be set correctly and so can't be used directly as a callback. Instead you'll need to use bind, such as obs.dispose.bind(obs).

3.5.0 release notes:

Important: This release includes some minor breaking changes to the foreach binding to improve performance and clarify features. These changes can be turned off using global options.

• When using the as option with the foreach binding, Knockout will set the named value for each item in the array but won't create a child context. In other words, when using as, you will have to use the named value in bindings: text: item.property rather than text: property. This can be controlled by setting ko.options.createChildContextWithAs = true. (See #907)
• To improve performance when array changes are from a known, single operation, such as push, the foreach binding no longer filters out destroyed items by default. To turn this off and filter out destroyed items, you can set includeDestroyed: false in the foreach binding or set ko.options.foreachHidesDestroyed = true to use the previous behavior by default. (See #2324)
