User:DrakRoar/SSBU patch summary

A quickly navigable compilation of all patch changes found in Ultimate, in the same vein as my Smash 4 compilation. Worth noting is:

• This doesn't include any minor visual changes.
• For moves with changed lag, (*) indicates a frame speed multiplier (FSM) was used, meaning the move as a whole is slowed down or sped up, rather than the active or interruptible frames being directly changed, which often results in other aspects like autocancel windows being indirectly altered.
  • Some moves have their FSM listed as starting from "frame 0". This happens when the FSM is declared in a script before any frame is specified, and causes an odd quirk; if it's lower than 1×, timing-based parameters outside of the script (like intangibility or FAF) start from frame 1 as usual, but parameters inside the script (anything else like hitboxes or charge windows) are treated as starting from "frame 0", effectively delaying them by one frame.
    • For example, if a move hits on frame 11 and has a FAF of 31, a FSM of 0.7× on frames 1-10 reduces it to frame 8 with a FAF of 28, but on frames 0-10 (if it's not specified to start on frame 1), this reduces it to frame 9 with a FAF of 28.
• For moves with changed knockback, (K%) lists their KO percent (taken from the Smash Ultimate KO calculator) on Cloud, from the center of Final Destination (unless otherwise noted), with rage/staleness off, no DI, and multi-hit damage excluded. This is mostly for comparison purposes, not to show the moves' KO potential in realistic scenarios. For convenience, this isn't listed for moves that can't KO below 300%.
• Ledge grab window changes refer to the earliest frame the character can snap to the ledge; the actual window is enabled one frame earlier, but a character's ledge grab boxes need to be in a ledge's range for at least one frame before they can snap to it.
• 1.1.0 was available right upon the game's release as a patch to 1.0.0. To denote this, 1.1.0 changes are marked in grey, since there was no proper metagame development for 1.0.0.

This was creating more downtime than a single perfect shield. Shortened the downtime when performing a perfect shield against projectiles.

Now, you will only dodge after landing if you input the direction after landing.
