This page provides information about versioning of Pdfcrowd products.
Pdfcrowd runs multiple converter versions that perform conversions between document formats. These converters are available via an HTTP interface (API) that is also versioned. Additionally, there are API client libraries (SKDs) for many programming languages and frameworks that allow easy implementation of the API and these client-side libraries are versioned as well.
In general, older versions are frozen and do not receive any fixes or updates.
The Pdfcrowd API provides access to converters.
Different versions may produce different results. The newer versions should provide better support for latest web technologies.
The version number consists of three parts: "major.minor.patch". The patch number is incremented for minor changes and bug fixes which do not change the API. The minor version is incremented for releases which add new, but backward-compatible, API features. The major version is incremented for API changes which are not fully backward-compatible.
Each release is bound to a particular converter version. This can be explicitly overriden with setConverterVersion().
The free version uses the latest converter version. Paying users can select the converter.
