WiX v3.10 Release Candidate build available

The WiX v3.10 Release Candidate build is now available! The focus of the WiX v3.10 release is supporting Visual Studio 2015 and Windows 10. As anticipated — almost like it was intentional — we’ve also fixed a number of bugs and implemented a small number of small features, but nothing big or risky.

We’re now ramping up the bug bar on WiX v3.10. That means bugs have to be really serious to get approved for v3.10. Don’t let that stop you from reporting bugs–we have plenty of numbers left in the v3.x series.

The plan for the RTM release of WiX v3.10 is to wait. Windows 10 ships 29-July and presumably Visual Studio 2015 ships shortly thereafter. As soon as Visual Studio 2015 RTM ships, we’ll put out a call for eyes to take a look and help verify that WiX continues to work with the RTM bits as expected. We’ll allow a short time to get feedback, then declare RTM.

Please download the RC release and help us get v3.10 across the finish line!

The WiX Tutorial has a new home

Gábor started the WiX Tutorial during the WiX v2.0 days. (Ah, we were all so young, then.) Over the years, the tutorial has grown to cover WiX v3.x and built a localization project to help contribute localizations to the WiX project.

Now the WiX Tutorial has moved to FireGiant. Take a look at the blog post I wrote to announce it. Then take a look at the tutorial itself. And do let us know what you’d like to see in the tutorial going forward!

WiX v3.10 version twist

After a brief hiatus for releasing WiX v3.9 R2, weekly builds for WiX v3.10 have resumed. WiX v3.10.0.1403 is now available — and you might have noticed an oddity in the version number.

When we started discussing the need to ship a maintenance release for WiX v3.9, we realized that we had no way to easily differentiate a maintenance release from the original “final” release — or any other pre-release build, for that matter.

Traditionally, WiX version numbers have been based on using three fields: major.minor.build. You likely know why: Because Windows Installer uses three version fields and ignores the fourth. Unfortunately, when you want to keep using major.minor versioning, that leaves only one field to identify a particular build.

So we decided to switch things around a bit. We’re now versioning the WiX bundle as major.minor.release.build. The release value is currently zero and will stay that way until/unless we ship a maintenance release. For example, WiX v3.10 RTM might be v3.10.0.2010 and a theoretical WiX v3.10 SP1 might be v3.10.1.2323.

The MSI packages in the WiX bundle continue to be versioned as major.minor.build.0, so that major upgrades keep working. The same is true of WiX executables. That means that, for example, Candle.exe from the aforementioned theoretical WiX v3.10 SP1 would have a version of v3.10.2323.0.

I’d rather all the versions — bundle, MSIs, and executables — have the same version number but tagging the bundle with release information is important enough to make this change.

Consequences

Unfortunately, the new versioning scheme means that new builds of WiX v3.10 are always seen as “less than” any of the already-released WiX v3.10 builds with the old numbering. That means that if you have v3.10.1124.0 installed, for example, v3.10.0.1403 will not be seen as an upgrade. The WiX BA blocks downgrades by hiding the big Install button:

WixNoDowngradeThe workaround is to uninstall any other build of WiX v3.10. Then v3.10.0.1403 will install normally.

WiX Toolset v3.9 R2 maintenance release is available

WiX Toolset v3.9 R2 is a maintenance release of WiX v3.9 that fixes several serious bugs:

  • Bug 4600 | VSExtension Help custom action binaries are corrupt.
  • Bug 4608 | Multiple prerequisites return failure, when 1st prerequisite is already installed and 2nd prerequisite is installed successfully.
  • Bug 4609 | Bug in BVariantCopy() in src/burn/engine/variant.cpp

Thanks to @rseanhall and @firegiantco for fixing these bugs.

WiX Toolset v3.9 R2 is v3.9.1208.0 and is available from Codeplex.

 

WiX v3.10 begins and is already mostly done

The first interim build of WiX v3.10 has been released: WiX v3.10.1124.0 from wixtoolset.org. It includes support for integrating Votive into Visual Studio 2015 Preview and native and managed libraries for VS2015.

And that’s most of what we intend to accomplish with WiX v3.10. We will — of course! — fix bugs and add some small features in WiX v3.10 but the focus is on supporting Visual Studio 2015 and, if necessary, Windows 10. Rather than filling the available schedule with work, the goal is to finish the planned work quickly and be ready to ship WiX v3.10 as soon as possible after Visual Studio 2015 ships.

To do that, WiX v3.10 won’t include any large new features, to reduce the risk of long bug tails. We’ll release milestone builds around new milestone builds of VS2015 to make sure changes in VS2015 are reflected in WiX v3.10. Bug fixes and small features are welcome and a few are already queued up in pull requests on GitHub. More are welcome! Let’s talk on wix-devs.
