Namirial is offering several (typically 4) major feature-stream releases per year, and in addition one Long-Term Support (LTS) version. The LTS version is based on a former feature-stream release which was in use already for a while. Focus on LTS releases is on security and stability, as well as on longer availability of hotfixes for stability and security issues.
For feature releases (e.g. 20.14, 20.28) Namirial offers software maintainance upon release date of the next feature release. After that date, customers who need a fix on a feature release are asked to update to the latest feature release, till they can upgrade to the next LTS release. For LTS releases (which we will release once a year), Namirial provides software maintenance by offering hotfixes for critical/blocker issues (classification is upon Namirial) for up to 2 years.
Our recommendation to our On-Premise and Private-Saas custmers is to use the latest LTS version whenever a customer is not requiring new features that have been introduced after release of the LTS version. On our Shared SaaS environments (including saas.esignanywhere.net, www.significant.com and others) we deploy feature-stream releases. The feature-stream releases may also be deployed by our customers e.g. when they need new features not yet included in the LTS version.
Version Numbering Scheme
Since 2020, SIGNificant Server Platform and eSignAnyWhere are following a version numbering scheme which reflects in average the release date. The major version number (19, 20, ...) reflects the calendar year of feature freeze. The minor version number (14, 28, ...) reflect the calendar week of planned release date (defined already before beginning of dev cycle). For LTS versions, which are based in general on the latest version of a year, the minor version number is ".76" The LTS version 19.LTS is published in spring 2020 and so-called "20 LTS", but based on the features of 2019 (so, 19.76). The LTS version released in sprint 2021 was numbered as 20.76.
Until end of 2019, SIGNificant Server Platform and eSignAnyWhere followed a different numbering model; the latest SSP version released under the old versioning number was SIGNificant Server Platform 4.22 released in late 2019. SIGNificant Server Platform 4.22 was compatible with eSignAnyWhere 3.7.
