Also have any records been changed?
New SQ1 World Record (not sure when it was/how long ago it was)
Bell V2M is good and most say better than the V1 with it's new magnet adjustment features.
MGC Repulsion 3x3, a new 3x3 with repelling magnets at 45 degrees.
GAN have a series called Monster Go which is their training puzzles.
Also welcome back.
Other updates:
GAN have made a pyraminx and an upcoming skewb, as well as their 2020 flagship the 11M Pro which is very good.
MoYu made a WRM megaminx a while back with ridges (which defeats the purpose of WR)
They have also released some cool non wca puzzles, a WRM 2020 and RS3M 2020 which has been the best selling puzzle of 2020. They have also made a 4x4 and 2x2 to go with the RS 2020 line.
Qiyi have made a Shadow V2M 6x6, along with updating their "Qi" budget series from a while back. They also made an XMAN 2x2 with adjustable magnets releasing in a week or 2.
YuXin have worked on their Huanglong line making a flat 13x13, the biggest one without pillowing.
YJ are working on their MGc line as well as releasing a mini series known as the Zhilong series consisting of 3x3 to 5x5.
