Oracle Application Express 4.2.1 is now released and available for download. If you wish to download the full release of Oracle Application Express 4.2.1, you can get it from the Downloads page on OTN. If you have Application Express 4.2 already installed, then you need to download the APEX 4.2.1 patch set from My Oracle Support. Look up patch number 14732511.
As is stated in the patch set note that accompanies the Oracle Application Express 4.2.1 patch set:
- If you have Oracle Application Express release 4.2 installed, download the Oracle Application Express 4.2.1 patch set from My Oracle Support and apply it. Remember - patch number 14732511.
- If you have Oracle Application Express release 4.1.1 or earlier installed (including Oracle HTML DB release 1.5), download and install the entire Oracle Application Express 4.2.1 release from the Oracle Technology Network (OTN).
- If you do not have Oracle Application Express installed, download and install the entire Oracle Application Express 4.2.1 release from the Oracle Technology Network (OTN).
As usual, there are a large number of issues corrected in the Application Express 4.2.1 patch set. You can see the full list in the patch set note.
P.S. Don't be alarmed when the patch set note refers to file p14732511_421_GENERIC.zip and the file you actually download from My Oracle Support is p14732511_420_Generic.zip. These are the same file and this version number will be corrected over the weekend.
