Product Version Quick-Reference Chart

The Actian Zen (formerly Pervasive PSQL) product has seen much change and growth over its 40+ years of development. The charts on this page were created to help you quickly visualize the major differences between each of the product releases over time.

The first chart provides a list of the major features available and which version first included that feature. The second chart shows the supported operating systems in each release. The third chart shows you which development API's are supported within each release. Finally, the last chart shows you the major release and support dates for each version.

Major Features by Actian Zen/PSQL Product Versions

¹ Only SOME distributions of Btrieve 6.15 included the ODBC drivers. Others did not include it, but it may have been available at an additional cost.

² Backup Agent is a free component on Server Engines only. It can be installed onto the Workgroup Engine, but a license must be purchased at additional cost.

³ Files with Long Owner Name 1 can be read on these versions, but these engines cannot create files with this long owner name format.

⁴ Files using this feature can be read on Zen v14 or higher ONLY. If you copy these files back to v13 or older, they will be unreadable.

⁵ Sector sizes over 4K are a hardware function of the physical hardware and cannot be changed. This hardware is supported in v14.21 Update 6 and higher, and v15.10 and higher.

⁶ Files using this feature can be read on Zen v15.10 or higher ONLY. If you copy these files back to v15.00 or older, they will be unreadable.

⁷ Files using this feature can be read on Zen v16.00 or higher ONLY. If you copy these files back to v15 or older, they will be unreadable.

Supported Operating Systems by Actian Zen/PSQL Product Versions

Sometimes you need to run with older or newer operating systems, so here is a chart showing the supported database versions for each OS.

Developer API's Available by Actian Zen/PSQL Product Versions

The developer API's are accessible from a variety of programming environments and languages, including Assembler, BASIC, C, C++, C#, Pascal, Delphi, Fortran, Several COBOL variants, and many more. If you are programming with a specific API, though, then you may need to know which versions suport that API.

¹ Btrieve 16-bit applications can be supported on the newer enviroments by copying the 16-bit components from the PSQL v9 Client to the system.

² Existing applications written with these APIs will still work, but the APIs have been deprecated.

Important Dates by Actian Zen/PSQL Product Versions

And finally, flipping the chart sideways, we can show the release dates, End of General Availability, and End of Support Dates for each version.

In June 2024, Actian changed their support model and provided new phases, but with no new descriptions, so we don't yet understand what these terms actually mean. Right now, your guess is as good as mine, but we'll update this when we know more.

Of course, this information is provided simply as a quick-reference chart and should NOT be considered the final word on supported features or platforms, as there are sometimes idiosyncrasies that cannot be easily depicted in this format. For example, some features may only be in specific sub-versions. In short, use this data with caution, and refer back to the official product manuals from Actian for the final word on support.
