News about Dyalog

Jan 2, 2024

Our new licence structure took effect on 1 January 2024; this article describes the changes from the previous structure.

Single Commercial Developer Licence Type

We have simplified the licence structure for commercial developer licences and now offer a single, multi-platform, developer licence. This includes:

• Supported platforms: Microsoft Windows, macOS, and Linux
• Widths: 32-bit and 64-bit.

This licence type also includes Dyalog Support Service (DSS), which offers support, maintenance, and upgrades.

The annual subscription price for a single commercial developer licence will be £1,375.

NOTE: If you have any commercial 64-bit or 32-bit developer licences, all your current licences must be upgraded to the new multi-platform developer licence on your 2024 renewal date. For example, if you currently hold a single 64-bit commercial developer licence for Microsoft Windows at £1,275 per year, your 2024 renewal/upgrade price will be £1,375 and your licence will be changed to the multi-platform licence.

32-bit Dyalog

It is more than 15 years since we introduced the 64-bit version of Dyalog. Since then, we have provided and supported both 64-bit and 32-bit versions of Dyalog. However, we have found it increasingly difficult to maintain the same level of functionality for both versions; considering the additional efforts to keep the 32-bit version functional, we have decided that it no longer makes sense to offer the 32-bit licence as a separate product at a lower price than the 64-bit version. The 32-bit version is included in the multi-platform developer licence.

We will also no longer offer 32-bit-only run-time licences. Run-time licences will continue to be priced per user, and from 1 January 2024 will include rights to distribute both 32-bit and 64-bit versions of Dyalog.

We will be contacting all customers with active 32-bit licences (developer/run-time) within the next few months with detailed information regarding how these changes will affect them directly. We will provide a detailed breakdown of any licences affected and the cost of upgrading them to the new multi-platform developer, along with payment options to enable customers to incrementally increase the cost over a five year period.

Basic Licence

There are no changes to the Basic Licence, which allows APL users to have a copy of the latest Dyalog technology for personal or non-commercial use and experimentation.

Special Contracts

Customers who have negotiated royalty agreements and other special contracts with us will not be impacted by these changes.

DSS+ Only Subscriptions

Customers who hold historic perpetual licences with an annual DSS+ subscription fee will be able to retain their historical licence and continue to pay for DSS+ only. However, the annual cost of DSS+ will increase to £865 per licence. Customers who have DSS+ only on a historical 32-bit perpetual licence will have to pay a one-time upgrade fee of £450 per licence to upgrade their DSS+ to the new structure.

NOTE: DSS+ only subscriptions apply to historic perpetual licences, and are not available to anyone who does not already have this licence type.
