changed behaviour in I2C LCD

Question

I reinstalled a previously working sketch to my UNO and now the behaviour of the lcd has changed.

Previously this example worked perfectly:

#include <Wire.h> 
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27,16,2);  // set the LCD address to 0x27 for a 16 chars and 2 line display

void setup()
{
  lcd.init();                      // initialize the lcd 

  // Print a message to the LCD.
  lcd.backlight();
  lcd.print("Hello, world!");
}

void loop()
{
}

Now it only displays the very first character 'H'

This version does work though:

#include <Wire.h> 
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27,16,2);  // set the LCD address to 0x27 for a 16 chars and 2 line display

void setup()
{
  lcd.init();                      // initialize the lcd 

  // Print a message to the LCD.
  lcd.backlight();
  lcd.print("H");
  lcd.print("e");
  lcd.print("l");
  lcd.print("l");
  lcd.print("o");
  lcd.print(" ");
  lcd.print("W");
  lcd.print("o");
  lcd.print("r");
  lcd.print("l");
  lcd.print("d");  
}

void loop()
{
}

Can anyone shed me any light what is the reason of this change in behaviour and how to solve it?

There seems to be an incompatibility between recent versions of the IDE and the library I was using.

Installing the latest version of the library from GitHub and replacing the lcd.init() command with lcd.begin() in my sketches solved the problem.
