I don't get it at all to be honest 
there is Bitcoin Core 0.10.0c1 available for download and 0.9.4 ? make no sense 

[allgoodthings1]

The 0.10.0c1 is a pre-release, development version.. to be replaced by the official 0.9.4 version.  I think the Linux iteration of the official version release is usually published first.  This is what you have here.

How to Upgrade
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).

OpenSSL Warning
OpenSSL 1.0.0p / 1.0.1k was recently released and is being pushed out by various operating system maintainers. Review by Gregory Maxwell determined that this update is incompatible with the Bitcoin system and could lead to consensus forks.

Bitcoin Core released binaries from https://bitcoin.org are unaffected, as are any built with the gitian deterministic build system.

However, if you are running either

The Ubuntu PPA from https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin
A third-party or self-compiled Bitcoin Core
upgrade to Bitcoin Core 0.9.4, which includes a workaround, before updating OpenSSL.

The incompatibility is due to the OpenSSL update changing the behavior of ECDSA validation to reject any signature which is not encoded in a very rigid manner. This was a result of OpenSSL's change for CVE-2014-8275 "Certificate fingerprints can be modified".

We are specifically aware of potential hard-forks due to signature encoding handling and had been hoping to close them via BIP62 in 0.10. BIP62's purpose is to improve transaction malleability handling and as a side effect rigidly defines the encoding for signatures, but the overall scope of BIP62 has made it take longer than we'd like to deploy.

Oh I see , I didn't knew that .
any idea when the Windows version is going to be available ? or it is already ?

@Chemistry1988 , for some reasons your link https://bitcoin.org/bin/0.9.4/ is going back to bitcoin.org homepage so I can't really download or see the windows version

[allgoodthings1]

The Windows iteration is not available yet.  I just checked.  Someone else might know the expected release date.

Yup, it hasn't been put on bitcoin.org yet. The release note has been prepared by the devs in advance though.
