Delphi 202110b Mega Better Review

Even a "Mega Better" release has edge cases.

Pitfall 1: Existing projects using WinAPI.Windows may throw E2003 Undeclared identifier: 'RT_RCDATA'.

Pitfall 2: The new LSP disables some third-party experts (like GExperts or CnWizards).

Pitfall 3: Android 64-bit debugging on older devices.

First, let’s demystify the nomenclature. In Embarcadero’s versioning schema, "2021" refers to the Rad Studio 11 release cycle. The "10b" typically indicates a specific patch or Update 1 build (sometimes referred to as the "Spring 2022" roll-up). However, the community moniker "Mega Better" isn't just marketing jargon—it represents the cumulative quality-of-life improvements, bug fixes, and performance leaps found in the 11.1.5 (internal build 202110b) iteration.

Users who migrated from Delphi 10.4 Sydney or the initial buggy release of 11.0 universally agree: 202110b is the stable foundation Delphi needed.

Software versions often lie. A major number jump promises the world but delivers bug fixes. But here, the “b” stands for honesty. It acknowledges that 10.4 Sydney (released mid-2020) was a foundation, and 2021.10b is the superstructure. Embarcadero, Delphi’s steward, has learned that developers don’t need fireworks — they need reliability. They need the IDE not to crash when opening a form with 200 components. They need the debugger to inspect a generic list without falling into a black hole.

“Mega Better” means:

These are not glamorous bullet points. They are the stitches that hold a professional’s day together.
