Yes there was....they redid multiple level concourses, the ribbon boards, video boards, scoreboard, etc
That being said.....they are planning upgrades
"To coin a hockey term, expect multi-year changes on the fly at KeyBank Center.
Fans attending Buffalo Sabres games and other arena events are going to see immediate differences this season with upgrades in food and beverage, both in products and point-of-sale technology.
New Buffalo Sabres COO John Roth knows there's lots of work to be done on the franchise's business side
John Roth, the newly hired COO of the Buffalo Sabres and Pegula Sports & Entertainment, spoke to The Buffalo News in an exclusive interview.
But other major items are coming on board starting in 2024, Sabres Chief Operating Officer John Roth revealed in an exclusive conversation with The Buffalo News.
The key takeaways the team is planning to address:
Replacing the arena’s main center-hung scoreboard for the ‘24-’25 season, upgrading a board that dates to 2007 and has fallen far behind its counterparts across the NHL. At 22 feet by 12.6 feet, its video display is one of the five smallest in the league.
Addressing and upgrading the arena’s sound system, studying the acoustics and the work of the lapendary panels that hang from the ceiling.
Replacing the arena’s roof, which is the original version dating to the building’s 1996 opening
In succeeding years, addressing the seating bowl as the team may look to make major revisions to the 27-year-old building with an eye on gathering areas that have become popular in arenas and stadiums across the country."
