ApexDC++ 1.6.4 maintenance update available

We are pleased to announce the immediate availability of another maintenance update 1.6.4.

This version fixes connectivity issues with compressed transfers caused by recent updates to the zlib library that we use. These connectivity issues randomly affect both downloads and uploads with clients that are running an affected version of zlib without the appropriate fix included. Additionally OpenSSL and zlib dependencies have also been updated once again, in order to keep things current.

For the people who still need the XP compatible binaries, we would like to take this chance to once more remind you about recent changes in release packaging for your operating system.

A full list of changes are available on here. As usual we strongly recommend upgrading to 1.6.4 as soon as possible.

ApexDC++ 1.6.3 maintenance update available

It has been quite a while again.

We are pleased to announce the immediate availability of 1.6.3 a maintenance update continuing in the same vein as the two before it. This time the focus is on updating third party dependencies and build tools with the latest security updates and patches. Notably the binaries distributed for the Windows XP operating system had a configuration issue for the previous version and this has now been addressed for our friends still in the past.

A full list of changes are available on here. As usual we strongly recommend upgrading to 1.6.3 as soon as possible, regardless of which version of Windows you happen to be running. For the people who need the XP compatible binaries, we would like to give this remainder about changes introduced in release packaging with the previous version.

Download: ApexDC++ 1.6.3

Update: 1.6.3 has an issue with compressed transfers, that affects connectivity, turning off the setting "Enable safe and compressed transfers" should avoid this issue on 1.6.3. Alternatively you can hold off upgrading until a fix is available.

ApexDC++ 1.6.2 - NMDC exploit fix

We are pleased to announce the immediate availability of 1.6.2. This update fixes an exploit that allowed users to send malicious search requests to a hub, causing a large flood of UDP traffic to a specified IP address.

OpenCandy, the recommendation engine behind sponsored programs in the installer, has now been removed. You should no longer be offered any additional software when running the setup file. They were terrible at responding and it wasn't worth the compromise.

WIndows XP binaries have been removed from the setup files and are included as a separate download. More information can be found in the forum post.

We're looking to include some minor improvements on the next version, so stay tuned for that.

ApexDC++ 1.6.1 security update

It's been too long since our last version - nearly two years!

We're pleased to announce 1.6.1 has been released and is available for immediate download. In this new version, we've focused on updating libs such as OpenSSL 1.0.2h (lots of security fixes), Inno Setup, Boost and MSVC 2015 Update 2.

Furthermore, we hope to have finally fixed the connectivity issues with encrypted connections and a rare crash when removing hubs from favourites. We no longer automatically add any hubs to favourites, as this has been removed in 1.6.1.

A full list of changes are available on here.

As 1.6.0 is so old, we strongly recommend upgrading to 1.6.1 as soon as possible.

Download: ApexDC++ 1.6.1

Update: The binary only slim package uploaded to SourceForge seems to have been corrupt, this has now been remedied. It might take some time for the new file to populate on all the mirrors, sorry for any inconvenience this may have caused.

Brief update

Just a quick update to notify you we have successfully transitioned to DigitalOcean and upgraded our forums to the latest instalment of IPS 4.

The server move has already proved to be a positive change in terms of performance and financial costs. We are now running PHP 5.6 and switched over from MySQL to MariaDB to follow the original developers - there's an article on this to bring you up to speed.

Although releases have become less frequent, we do plan on catching up with the latest OpenSSL and DC++ security related exploits as soon as we can. Cologic provided an insightful article on some of the changes we're looking to include, alongside that pesky NMDC exploit.

ApexDC++ 1.6.0 available for download

We have released 1.6.0 to address some security issues regarding hub hijacking and upgraded to the latest OpenSSL 1.0.1i. The hub domain was hijacked recently and therefore we have blocked this to prevent users connecting to this fraudulent hub. We have also changed the behaviour of the security settings page to ensure this won't happen again. Therefore, we highly recommend you upgrade to 1.6.0 as soon as possible.

Anybody experiencing connection issues on the previous versions using the adcs:// protocol should see this finally fixed in 1.6.0; thanks for your patience on this one.

Hope everyone's having a good Summer. B)

Security Advisory: ApexDC++ 1.5.14, OpenSSL fixes

We are pleased to announce immediate availability ApexDC++ 1.5.14, fixing security vulnerabilities found in the OpenSSL. The OpenSSL team had this to say about one of the vulnerabilities:

An attacker using a carefully crafted handshake can force the use of weak keying material in OpenSSL SSL/TLS clients and servers. This can be exploited by a Man-in-the-middle (MITM) attack where the attacker can decrypt and modify traffic from the attacked client and server.

Therefore we advise all users on previous versions to upgrade to 1.5.14 immediately. The installer will provide a smooth upgrade without losing any settings or your queue.

Check out our full changelog for further details.

ApexDC++ 1.5.13 maintenance release available

We have published a maintenance release available for immediate download. 1.5.13 fixes a small set of issues that can in the worst case scenario render your installation of ApexDC effectively unusable. You can check out the full changelog here. We recommend that you update your version of ApexDC as soon as possible.

Download: ApexDC++ 1.5.13

Update: The voting period has ended, thank you for everyone who participated.

We have been, presumably randomly or based on recent activity, selected for the community choice vote for SourceForge May Project of the Month (fairly new thing they have been doing). If you have a SourceForge account look at the projects listed and vote as you will... or don't, it is really up to you. But it would be a shame for us not to say anything at all, considering this isn't likely to happen again any time soon. We have so far been a featured project (a weekly thing, for handful of projects at a time) twice within the last two or three years.

Direct Connect hasn't been prominently featured in any way in recent memory. It would be nice to make that happen, as well as an achievement for the project of course.
