Release Notes

All platforms - Server, clients: Improvements in LZ4 compression when used with SSL.

LZ4 compression for metadata is still experimental, and we just fixed an issue in combination with SSL that made it use more bytes than without LZ4.

All platforms - Server: We added HTTPS support to the WebAdmin/WebUI!

The web server will automatically use the first certificate you configured in your network settings. This means that the web interface will use the same certificate you use for your Plastic SCM SSL connections automatically, without any further configuration. Just keep in mind that you'll need to access the server using https:// instead of http:// now!

If you change the certificate you use for the SSL port at some point, make sure you restart the server to refresh the certificate information in the WebAdmin/WebUI.

All platforms - Issue tracker extensions: We added some missing parameters in the issue tracking configuration example files.

All platforms - Bamboo plugin: We added support to perform customized runs.

This kind of runs let you specify the changeset to build. Before these changes, Bamboo considered those runs as simply building the latest contents.

All platforms - Server, Client: New expiration token system for LDAP.

When you enable LdapTokenPrivateKey in your server that is connected to LDAP, a new token expiration system will greatly reduce calls to LDAP.

This will greatly increase performance for command line applications, and overall server response.

The reason why we implemented this is to support external login systems in cloud2, but it will help in LDAP servers too.

All platforms - Server (.NET Core flavor): We moved the location of loader.log.conf in the .NET Core bundle.

You see, the ideal way of upgrading your Plastic SCM Server in custom setups (this is, when you DON'T use the installer) is just replacing the binaries. That's also pretty much what our Watchdog does when upgrading (although with some fancy steps such as preparing a sparse node to prevent downtimes and the like).

The issue is that if you just replace your binaries' directory contents with the content of the .zip or .tar.gz, you will override your loader.log.conf file! No more - we just moved it to the config_samples directory.

Windows - Plastic: Add scrollbars to the comment dialog you get after merging a branch or changeset to a different branch (merge-to operation).

The lack of scrollbars could be annoying if you typed a multi-line comment. We added a vertical scroll bar to help you with that.

All platforms - Server, clients: We enabled code optimization flags that will make serialization and deserialization faster.

We enabled optimization on some components that do CPU intensive operations. Optimizations were disabled because they caused issues with localization. We're trying to fix those issues to benefit from better serialization/deserialization speed. Clearly noticeable when sending big trees, big merges, etc.

Linux - Server: improved UDT data transfer speeds for Linux.

We tweaked some parameters in our .Net Core Udt implementation, and got a 300% performance increase when running on high latency connections. In our tests we downloaded 250 mb of data from a server in Singapore to a client in Paris.

We also found you can considerably boost udt download rates by increasing your udp receive buffer size, using the following command:

$ sysctl -w net.core.rmem_max=26214400

This helps to eliminate packet loss, which can slow down the transfer.

With that setting, we achieved transfer rates of 600 mbps using udt, compared with 70 mbps using tcp over the same connection.
