+The PBXT/PrimeBase engine is unsupported upstream in MySQL & MariaDB for some |
| 36 |
+time now [1]. It is no longer built in the upstream MariaDB 5.5 binaries[2][3] |
| 37 |
+and if it is enabled in a source build, it fails many tests [4]. |
| 38 |
+ |
| 39 |
+In light of this, the MySQL team has decided to mask it in |
| 40 |
+profiles/base/package.use.mask for all relevant packages. |

+All users who have data stored in PBXT-backed tables MUST convert the tables |
| 49 |
+to another format BEFORE upgrading to MySQL/MariaDB 5.5, as the tables will |
| 50 |
+become inaccessible otherwise. |
| 51 |
+ |
| 52 |
+We will continue to allow it to be built in the 5.0/5.1 series, to make the |
| 53 |
+above data migration easy, but we strongly encourage all users to move their |
| 54 |
+data out of the PBXT engine. |
| 55 |
+ |
| 56 |
+If you need to check for PBXT tables easily, look in your MySQL/MariaDB |
| 57 |
+datadir for any files with a .xt extension. |
