The law suit is apparently dropped, but both sides still appear to be casting what transpired differently.

From The Hill:

The Sanders team said the investigation vindicated them and showed no evidence that they improperly accessed information belonging to Hillary Clinton's campaign.

"An independent investigation of the firewall failures in the DNC’s shared voter file database has definitively confirmed that the original claims by the DNC and the Clinton campaign were wholly inaccurate," the campaign said in a statement.

"The Sanders campaign never 'stole' any voter file data; the Sanders campaign never 'exported' any unauthorized voter file data; and the Sanders campaign certainly never had access to the Clinton campaign’s 'strategic road map.'

But then it says the Hillary people say they were correct all along, too, and it (nearly) ends with this:

Both sides acknowledge that one summary sheet with data related to New Hampshire appeared to have been saved off-site, but the Sanders campaign argued that the file did not exist on their computers and was never seen by any Sanders staffer.

Hmmm - I'm not sure I know anything more than I did before I read that.

The Wall Street Journal appears to have fewer column inches on the story and only this bit of information beyond what was told by The Hill:

In a statement released Friday, the Sanders campaign accused both the DNC and the Clinton campaign of making “wholly inaccurate” statements in December about the breach based on the results of the independent investigation. The campaign said it never had access to proprietary data on voters that the Clinton campaign was targeting, only some “scores” showing the likelihood that a voter would support the Clinton campaign.

When in doubt, go to the source:
PRESS RELEASE
Independent Investigation Confirms Sanders Campaign Told the Truth

APRIL 29, 2016

BURLINGTON, Vt. – Four months ago, in an impulsive overreaction and at a critical point in the campaign just weeks before the closest Iowa caucus results in history, the DNC shut down the Sanders campaign’s access to its own voter file data, only restoring access after the campaign filed a lawsuit in Federal court.

Now, four months later, an independent investigation of the firewall failures in the DNC’s shared voter file database has definitively confirmed that the original claims by the DNC and the Clinton campaign were wholly inaccurate – the Sanders campaign never “stole” any voter file data; the Sanders campaign never “exported” any unauthorized voter file data; and the Sanders campaign certainly never had access to the Clinton campaign’s “strategic road map.”

In fact, the independent investigation has confirmed what the Sanders campaign said from the start:

The DNC’s security failures allowed four Sanders campaign staffers – three junior-level staffers led by a manager who had been hired at the recommendation of the DNC and who was immediately terminated after the incident – to have extremely short-lived access for one hour to Hillary for America’s scoring models, but not to any of Hillary for America’s proprietary voter data.

No one else in the Sanders campaign, outside these four staffers, accessed the Hillary for America’s scoring models or had knowledge that the activity was taking place until well after the incident was over.

With one exception, all unauthorized access took place within the DNC’s own system. While there is evidence that the terminated staffer may have exported a summary data table, the independent investigation of Sanders campaign computers could not locate that file and no one in the Sanders campaign has ever seen that file.

With the investigation behind us, the campaign has withdrawn its lawsuit against the DNC today but continues to implore the DNC to address the systemic instability that remains in its voter file system. It is imperative that the DNC make it a top priority to prevent future data security failures in the voter file system, failures that only serve as unnecessary distractions to the democratic process.

Bernie Sanders Campaign Manager Jeff Weaver said “We are gratified by the results of this independent investigation.”

So, no reporting has any comment on whether the DNC has, in fact, been able to beef up security in the VAN system.

There's a Wreck List piece at TOP with a lot of hot air about the significance of all this -I'm not finding much, however. YMMV.
