Skript 2.8.0-pre1

Skript 2.8.0 Pre-Release 1 is here for everyone to begin previewing! This release contains all major features for Skript 2.8.0. As a pre-release, be warned that there may be bugs! We do not recommend running this version on your production servers. We will release additional pre-releases as necessary. Per our new release model, we plan to release Skript 2.8.0 on January 15th.

Below, you can familiarize yourself with the changes. As always, report any issues to our issues page! We will be working over the next two weeks to address any issues that are found.

Happy New Year and Happy Skripting!

⚠ Breaking Changes

Using players in variable names will soon change from defaulting to names to defaulting to UUIDs. Warnings have been added to help smooth out this transition. See #6270 for more information.
Removed Projectile Bounce State condition and expression. These haven't done anything for years.
The target entity of player expression has been improved and now uses raytracing to find the player's target. This should cut down on false positives significantly, but the change in behavior may cause issues for some users who relied on its quirks.
Parsing players from player names is now a bit more intuitive. Previously, parsing "xyz" as a player would return the first online player to contain "xyz" somewhere in their name. Now, it only returns players that start with "xyz". See #5875 for more.
Major changes have been made to the on grow event. The grow event now has many more options to specify how you want it to listen. These changes mean that code that uses on grow of x may fire twice as often as expected.

# x -> something
on grow[th] from X

# something -> x
on grow[th] into X

# X -> Y
on grow[th] from X [in]to Y

# x is involved in some way
on grow[th] of X

The expression durability of %item% now actually returns the durability (a pick with durability 103/160, for example, returns 103) instead of the prior behavior, where it would act like damage of %item% (returning 57 for 103/160).
When there are multiple valid event-values for a default expression, Skript will now error and ask you to state which one you want instead of silently picking one. See the following example:

on right click on entity:
    send "test" 
    # This will now error, because Skript doesn't know whether to 
    # send it to the clicked entity or the player doing the clicking.

Arithmetic evaluation will now return <none> for a whole chain if one of the operations is illegal. Previously, adding 1 + "hello" would treat "hello" as 0 and just return 1. This now returns <none>. However, the behavior of adding things to unset values hasn't changed. 1 + {_none} still returns 1.
