🌲 #newfeature
Big news for coders interested in producing better script visuals! We can now generate colors on the fly, and use "series color" in more functions:

🌲 #newfeature
You can now initialize arrays with a list of values using the new array.from():

//@version=4
study("")
int[] v = array.from(1, 2, 12)
plot(array.avg(v))

🌲 #newfeature
When updating a published script, you can now choose to keep your previously published chart as is, only updating the script’s code.

🌲 #newfeature
color.new() now accepts arguments of "series" form for its color and transp parameters:

🌲 #newfeature
Script authors can now filter their user profile's SCRIPTS page on the access type of their scripts.

🌲 #newfeature
The "Publish Script" window was redesigned to make our options clearer.

🌲 #newfeature
tostring() now accepts three new formatting arguments:
format.mintick to format to tick precision.
format.volume to abbreviate large values.
format.percent to format percentages.

🌲 #newfeature
The new round_to_mintick() function makes it possible to round numeric values to tick precision.

🌲 #newfeature
Script authors can now filter their user profile's SCRIPTS page on private/public publications.

🌲 #newfeature
You can now use nz() to protect against division by zero. This will return zero when close == open: nz(1 / (close - open))

🌲 #newfeature
A new barstate.islastconfirmedhistory built-in allows you to detect the last bar in history. This can be useful to restrict calculations to the point just before the script begins execution on an open market.

🌲 #newfeature
When drawing lines, labels or boxes and using xloc.bar_index to position them, you can now use offsets of up to 500 bars into the future, e.g.: label.new(bar_index + 10, high, "Text")

🌲 #newfeature
Values changed in the "Settings/Inputs" and "Settings/Properties" tabs are now preserved as you save new versions of a script already loaded on a chart.

🌲 #newfeature
You can now use explicit_plot_zorder = true with study()/strategy() so that the order of plot, fills and hlines in your code determines their z-order, i.e., which ones appear on top of others. Other drawings are not affected.

🌲 #newfeature
Horizontal lines and boxes starting on early bars in history are now displayed on the chart, even if their starting point is not visible on the chart's bars:

//@version=4
study("", "", true)
var firstBarTime = time
if barstate.islastconfirmedhistory
    line.new(firstBarTime, close, time, close, xloc=xloc.bar_time)

🌲 #newfeature
Strategy results now show the Sortino ratio.
