The sequence was published as rapidly as possible. Rather than wait for the whole thing to be done and publish it in one go it was released in fragments. These were verified as they went and compiled into a draft version. When the majority was completed the missing bits and difficult parts like repeats were completed and eventually a finished sequence released.
Doesn't mean it is the same for everyone but its the best consensus sequence they are able to compile at the moment.

The draft sequence was released when the sequencers had a few repeats of each sequence they thought was in the genome. It had some gaps, some errors, even some sequences from other organisms in it. The entire thing has been sequenced many more times now, and there is finished sequence for quite a bit but not all of it. Finished sequence has no gaps, has the repeated sequence parts in/near genes sequenced carefully, and has no ambiguities left about its order of genes. But to finish a sequence requires a lot of effort focused on one particular region, sometimes just analysis but sometimes also resequencing parts of it where it's unclear. So not all of the human sequence has been finished. After the sequence is finished it is annotated, which involves finding the genes and giving at least a tentative idea (based on homology to known genes) of what they do.

The draft sequence had only the number and types of genes present in the Human genome.
but the Finished sequence had the nucleotide sequences of all the genes and also showed the similarities and disimilarities between Human and other animals on genetic basis.
The finished sequence helped in determining the evolution of Man and the animals nearer and distant to man in evolution.
