Release 33 came out of 3 March 2010. As of Sept 2009 the YHRD database
contained the following:
(from the Manual):

"1 Introduction

The YHRD1 (see Figure 1) aims to help with the interpretation of
results from comparisons of evidentiary samples typed with Y-STRs and
reference samples and to formulate conclusions. Since Y-STRs are
located on the nonrecombining part of the Y chromosome the profile
generated by Y-STR analysis should be considered as one trait coded by
one locus (a Haplotype). Consequently, the YHRD provides Haplotype
frequencies (>1 locus typed per sample) for common formats consisting
of 9-17 loci (see Table 1).

Table 1: Available loci sets

Since a strong substructure between and within continents exists for
Y-STR Haplotypes, the database must reflect the enrichment, scarcity
or admixture of Haplotypes in certain geographical regions or
continents. In contrast, different populations which share a common
ancestry have shown to be homogeneous. Such population samples with
none or small genetic distance can be joined to so-called
Metapopulations (e.g. the Western Europeans). Dependent on your choice
the database reports matches for the full database, a selected
Metapopulation, a national database or a certain population sample.
The database is fed by quality-assessed and certified forensic and
other labs from all around the world. Thus, the YHRD is a
meta-database aiming to implement all national database projects. The
database is explained in detail in Willuweit et al. (2007) and Roewer (2009).

2 Current state of the database

By September 2009 about 80,000 9-locus Haplotypes (and 23,000 YFiler
Haplotypes) (see Figure 2) from
600 sampling locations in 96 countries have been submitted by about
190 institutes and laboratories.
In geographic terms, about 43% of the YHRD samples are from Europe,
30% from Asia, 13% from
South America, 8% from North America and 5% from Africa.

We continuously receive new data from submitters (haplotypes, mutation
rates etc.) and update the YHRD
regularly. Since new releases replace the previous ones, the release
number and date is an important part
of the "Search result" document. The Release Notes are included in
the bottom line of all documents."

------------
It now includes Y SNPs in the database.
