V8 release v6.8

Every six weeks, we create a new branch of V8 as part of our release process. Each version is branched from V8’s Git master immediately before a Chrome Beta milestone. Today we’re pleased to announce our newest branch, V8 version 6.8, which is in beta until its release in coordination with Chrome 68 Stable in several weeks. V8 v6.8 is filled with all sorts of developer-facing goodies. This post provides a preview of some of the highlights in anticipation of the release.
JavaScript functions unnecessarily kept outer functions and their metadata (known as SharedFunctionInfo or SFI) alive. Especially in function-heavy code that relies on short-lived IIFEs, this could lead to spurious memory leaks. Before this change, an active Context (i.e. an on-heap representation of a function activation) kept the SFI alive of the function that created the context:

By letting the Context point to a ScopeInfo object which contains the stripped-down information

States Can Require Internet Tax Collection, Supreme Court Rules

The U.S. Supreme Court freed states and local governments to start collecting billions of dollars in sales taxes from internet retailers that don’t currently charge tax to their customers.Siding with states and traditional retailers on a 5-4 vote, the court overturned a 1992 ruling that had made much of the internet a tax-free zone. That decision had shielded retailers from tax-collection duties if they didn’t have a physical presence in a state.Writing for the court, Justice Anthony Kennedy said the 1992 ruling, which involved catalog sales, was “unsound” and obsolete in the e-commerce era.

Broader taxing power will let state and local governments collect an extra $8 billion to $23 billion a year, according to various estimates. All but five states impose sales taxes.Wayfair Inc. plunged as much as 9.5 percent on the news, and was down 7.5 percent to $107.45 at 10:20 a.m. in New York

WASHINGTON — Internet retailers can be required to collect sales taxes in states where they have no physical presence, the Supreme Court ruled on Thursday.Brick-and-mortar businesses have long complained that they are disadvantaged by having to charge sales taxes while many of their online competitors do not. States have said that they are missing out on tens of billions of dollars in annual revenue under a 1992 Supreme Court ruling that helped spur the rise of internet shopping.On Thursday, the court overruled that ruling, Quill Corporation v. North Dakota, which had said that the Constitution bars states from requiring businesses to collect sales taxes unless they have a substantial connection to the state.The vote was 5 to 4. Justice Anthony M. Kennedy wrote the majority opinion and was joined by Justices Clarence Thomas, Ruth Bader Ginsburg, Samuel A. Alito Jr. and Neil M. Gorsuch.In the years since 1992, three members
