CubePDF is a PDF converter in the form of a Windows virtual printer driver. By selecting the CubePDF printer when you press the print button in each application, it will convert the file to PDF instead of printing it on paper. You can also convert to a bitmap (image) file such as PNG or JPEG.
To understand 2021.10b, we first need to look at RAD Studio 11 Alexandria, released in September 2021. The “11” marked a significant leap forward, with highlights like:
However, as with any major release, early adopters encountered bugs, performance regressions, and quirks — especially in the debugger and Delphi LSP (Language Server Protocol) tooling.
Many enterprises skip Delphi 11 Alexandria (10.11) because of early breaking changes (especially with Custom Managed Records and TGrid). Instead, they jump from 2021.10b to Delphi 12 Athens or later.
Key caution: Delphi 11 and 12 have different package naming conventions (.dproj changes). Always test third-party components (DevExpress, TMS, Raize) for compatibility. delphi 2021.10b
Yes — if you are on RAD Studio 11.0 base release.
The 2021.10b update is safe, non-intrusive, and solves many early-adopter headaches. However, note that it is not the same as RAD Studio 11.1 (which came later with macOS ARM64 native compilation, newer Android SDK support, and over 150 fixes).
If you can upgrade to 11.1, 11.2, or 11.3, those are even more polished. But if you’re locked to 11.0 for compatibility reasons, 2021.10b is a must-have. To understand 2021
If you’ve been following the RAD Studio ecosystem closely, you know that 2021 was an active year for Delphi and C++Builder. Among the various patches and point releases, Delphi 2021.10b stands out as an important maintenance update that brought stability, tooling improvements, and critical fixes.
But what exactly is 2021.10b? Is it a major version, a hotfix, or something in between? Let’s break it down.
First and foremost, it is critical to clarify that Delphi 2021.10b is not a major release like Delphi 11 Alexandria or Delphi 12 Athens. Instead, 2021.10b refers to a specific Update 2 (or cumulative patch set) for Delphi 10.4 Sydney. However, as with any major release, early adopters
In Embarcadero’s versioning scheme, the year 2021 relates more to the time of the patch’s stability release than a standalone year-based edition. Many developers colloquially refer to this stabilized, fully patched state of Delphi 10.4 Sydney (Update 2 + hotfixes) as "Delphi 2021.10b".
Key takeaway: If you are maintaining a project last compiled with Delphi 2021.10b, you are essentially using Delphi 10.4.2 (build 10.4.2.10b).
The “10b” suffix isn’t cosmetic. It solves several critical regressions from Update 2’s initial release (10.4.2, build 10.4.2.10a). Major fixes include:
If you are running a mission-critical application compiled with a generic 10.4.2, the 2021.10b hotfixes likely resolve subtle runtime errors that would otherwise surface in production.
