What is the difference between processing L2A vs L2Ap?

<PROCESSING_LEVEL>Level-2Ap</PROCESSING_LEVEL>
<PRODUCT_TYPE>S2MSI2Ap</PRODUCT_TYPE>

<PROCESSING_LEVEL>Level-2A</PROCESSING_LEVEL>
<PRODUCT_TYPE>S2MSI2A</PRODUCT_TYPE>

Thanks

L2Ap are the pilot products generated by ESA until March 2018, after March, they are operational products (L2A). Please see:

OK, fine. But how do I determine processing level using Sen2Cor 2.5.5 ?
Somewhere in the GIPP file? Where?
Expecting level 2A but get level 2Ap.
From the output:
<GIPP_FILENAME type=“GIP_Level-2Ap” version=“2.5.5”>S2A_USER_MSI_L2A_TL_SGS__20151204T174534_A002350_T33VXC_N02.00</
