Amid the intense press coverage of the House memos, very little press coverage can be found about the Senate memo. It was initially released heavily redacted but was returned to the FBI to be made more transparent. Many redactions were removed. The memo is a referral to the FBI/DOJ for criminal investigation of Christopher Steele.
The memo can be found here:
https://www.judiciary.senate.gov/imo/media/doc/2018-02-06%20CEG%20LG%20to%20DOJ%20FBI%20(Unclassified%20Steele%20Referral).pdf
Some highlights: (from the Washington Examiner link below)
-The referral, which was first released in heavily redacted form on Monday, appears to confirm some level of coordination between the extended Clinton circle and the Obama administration in the effort to seek damaging information about then-candidate Trump.
-The unredacted referral does discuss the controversial FISA applications seeking permission to spy on former Trump campaign adviser Carter Page. The House Intel memo stressed that the effort to obtain a warrant to renew the surveillance would not have happened without the Trump dossier, which contained salacious and unverified claims about Trump's ties to Russia, and that DOJ officials knew Steele had an anti-Trump bias but made no mention of that in their effort to renew FISA surveillance on Page.
-the referral said the "application failed to disclose that the identities of Mr. Simpson’s ultimate clients were the Clinton campaign and the DNC.”
-The referral says that though the FBI suspended its relationship with Steele in October 2016 for unauthorized contact with the media, the agency defended his credibility before the Foreign Intelligence Surveillance Court multiple times under the assumption that Steele had told the truth when he said he had not contacted journalists. The Judiciary Committee said that documents and testimony it received showed that Steele provided dossier information to "numerous media organization" before his relationship with the FBI was terminated.

The NYTimes says:
Two leading Senate Republicans released a document late Tuesday that they said bolstered Republican allegations that the Justice Department relied heavily on a politically tainted dossier in seeking permission from a secret federal court to eavesdrop on a former Trump campaign aide.
-
The Senate letter accuses the F.B.I. of relying largely on unverified information produced for the Democratic National Committee and Hillary Clinton’s presidential campaign to convince a federal judge of the need to eavesdrop on Mr. Page as a possible Russian agent.
The letter said the Justice Department’s initial application to the Foreign Intelligence Surveillance Court to spy on Mr. Page, filed in October 2016 after he had left the Trump campaign, “appears to contain no additional information corroborating the dossier allegations” posed by Christopher Steele, a former British intelligence agent who had been working with a research firm paid by the Democrats. That court approved the surveillance for 90 days, and renewed it three times.
