1374 * Version 4.10 - New to 1.9.16p2, lost in space 1.9.16p3 to 1.9.16p9
1375 * - Reappeared in 1.9.16p11 with fixed smbd services
1376 * Version 4.20 - To indicate that nmbd and browsing now works better
1377 * Version 4.50 - Set at release of samba-2.2.0 by JHT
1379 * Note: In the presence of NT4.X do not set above 4.9
1380 * Setting this above 4.9 can have undesired side-effects.
1381 * This may change again in Samba-3.0 after further testing. JHT
