Here we go ;)

Downloaded, validated the signatures and uncompressed the files. => Passed.
On the README.txt file, checked link for 6. => 404 page not found. since
current directory doesn't exist, other links will fail too.
Checked the CHANGE.txt file => Seems to be ok.
Randomly checked the documentation => docs/bulk-loads.html point to an
external page. Should it not be to a local one?
Ran all tests => Passed.
Started it, looked at the logs, the UI, all is fine.
Ran PE, results similar between 0.94.9 and 0.94.10 (Numbers below are ms
spent to run the test, average on 10 tests.)
||Test||0.94.9||0.94.10||
|org.apache.hadoop.hbase.PerformanceEvaluation$FilteredScanTest|2172297.6|2141379.4|
|org.apache.hadoop.hbase.PerformanceEvaluation$RandomReadTest|2574442.3|2533646.4|
|org.apache.hadoop.hbase.PerformanceEvaluation$RandomScanWithRange100Test|19098.3|19205|
|org.apache.hadoop.hbase.PerformanceEvaluation$RandomSeekScanTest|154499.7|153022.8|
|org.apache.hadoop.hbase.PerformanceEvaluation$RandomWriteTest|84760.2|85176.2|
|org.apache.hadoop.hbase.PerformanceEvaluation$SequentialWriteTest|43636.175|44185.7375|

Did rolling restart on a 8 node cluster, restarted the master => Ok.
Checked the logs and UI => Ok.
Stopped master, configured balancer to default, merged a 71 region table
into one single region => Ok.
Major compacted the table, got it automatically splited to 2 regions,
manually split it to 32 regions, waited for balancer => Ok.
Stopped master again, reconfigured custom balancer, restarted, rebalanced
=> Ok.
>From shell: Create table, scan, balance, drop => Ok.

IntegrationTestLoadAndVerify still give strange results =>
REFERENCES_CHECKED=9855348 (Should be 10000000)
Ran IntegrationTestBigLinkedList => Perfect.

So a big overall +1 for me ;)

Deployed in my "prod" cluster. Thanks all for this release.
