The NHL and NHL general managers discussed a very important change.
"One of the agenda items for the GMs meeting is the timing of game-day practices. It should be moved up by 30 minutes, so 10:00 for the home team and 11:00 for the visiting team. The change will need to be approved this week." - Renaud Lavoie
It may seem trivial, but it's a good change to the players' routine. These athletes have very strict routines, and they follow them to the minute.
It's also a good change for players who like to arrive earlier and get on the ice before practices. In short, it will certainly have an impact.
There are also other topics that have been addressed, as mentioned by the Habsolutely Fan site.
"To crack down on blindside hits to prevent injuries.
To impose a penalty on players who sit on the boards for long seconds waiting for a line change, to avoid potential injuries to a player or a linesman skating backward near the bench.
Possibility of sending the same player multiple times in shootouts.
