The run could freeze after alt-tabbing out and back - the board stopped responding while the menu, surrender and restart still worked. This is the soft-lock some of you hit more than once. Note the new behaviour: alt-tab no longer pauses the game at all - press ESC first if you want it paused, like most games.
Genie Lamp picked up in the last seconds before an extraction checkpoint lost its whole arrival cinematic. It now waits behind the checkpoint and plays in full when you keep going.
Burst and Moon bubbles drew a faint square around themselves while splitting.
The trophy statue on the shelf was tracking the wrong achievement - it now tracks "Who's the Boss Now?".

The red-skull wipe could crash the run on a Spine board.
The aim line read as if it was skewering the DNA core.
The Attack Damage card showed the wrong number at very high values.
Enemy damage now shows a number, and the Energy card no longer claims a bonus it was not giving.
Mine alarms stacked into a wall of noise - a mine's alarm now stops the moment that mine does.

The results screen played a victory cheer even when you had just died. That is for new records only now.
Changes
Main game
Easy is more beatable. The Eye, and every location from The Chronos onward, now ask 20% less XP at every gate on Easy. The Drone and The Camera are unchanged, and Hard and Insane are untouched everywhere.
The power bar stretches after the 20th power-up. Past that point the gap between power-ups grows by an increasing amount each time, so a deep run stops handing out power-ups by the hundred. The first 20 are exactly as they were. This also applies to BUBBLEATHON, which shares the same bar.
Mad Ducky's BATH TIME intro is polished
HELIX DISCOVERY (arcade)
Runs can be lost, and therefore finished. Boss health and your damage no longer climb as one number, so a fight can actually end.
Mines you shoot down drop black marbles.
Filling the power bar while every power is already charged now pays out bonus globes.
Your DNA core wears its health in its centre, in the core's own colours, and reacts as it crosses 75%, 50%, 25% and 5%.
The Helix TV boss now picks a bubble every 5 seconds instead of every 10.
The Helix Blade spins the way it does in the main game, and knocking it off course takes real commitment.
