Why has the phonetic symbol been changed?

For the transcription of the vowel /u/ as in "thank YOU", a change has been made in the latest International Phonetic Symbol. The symbol for /u/, familiar to me for long, has been transcripted as ʊ (Sorry, the screen won't display the symbol) . I was wondering why is this change. What is the cause for this?

Nope, no change has been made.

<<The symbol for /u/, familiar to me for long, has been transcripted as ʊ (Sorry, the screen won't display the symbol).>>

[u] and [ʊ] are both well-established IPA symbols, and they refer to different vowels. If you saw somebody transcribe "thank you" with [ʊ], then either they were transcribing an old-fashioned RP pronunciation, or they just didn't know how to transcribe things correctly.

Sometimes the computer makes the second symbol when it can't make the first symbol.
