Can't import stringutils on Ballerina

I'm trying the basics with the following code:

import ballerina/io;
import ballerina/stringutils;
 
public function main() {
    string str1 = "Comparing String";
    string str2 = "cOmpaRinG sTrinG";
    io:print("String '" + str1 + "' and '" + str2 + "' are");
    if (stringutils:equalsIgnoreCase(str1, str2)) {
        io:println(" equal");
    } else {
        io:println(" not equal");
    }
}

But I get an error:

caio@german_shepherd test % bal run ./string.bal
Compiling source
    string.bal
ERROR [string.bal:(2:1,2:30)] cannot resolve module 'ballerina/stringutils'
ERROR [string.bal:(8:9,8:49)] undefined function 'equalsIgnoreCase'
ERROR [string.bal:(8:9,8:49)] undefined module 'stringutils'
error: compilation contains errors
caio@german_shepherd test % bal -v
Ballerina Swan Lake Beta 2
Language specification 2021R1
Update Tool 1.3.5
caio@german_shepherd test % sudo bal dist use slbeta2
Password:
'slbeta2' is the current active distribution version

I see the same error while editing the code on VSC. What is missing?

ballerina/stringutils module is removed with Swan Lake Beta 1 release. The "regex" related APIs were moved to ballerina/regex [1] module and rest of the APIs are available at langlib string library [2].

Therefore we need to update your code sample as follows:

import ballerina/io;
 
public function main() {
    string str1 = "Comparing String";
    string str2 = "cOmpaRinG sTrinG";
    io:print("String '" + str1 + "' and '" + str2 + "' are");
    if ('string:equalsIgnoreCaseAscii(str1, str2)) {
        io:println(" equal");
    } else {
        io:println(" not equal");
    }
}
