Delphi - 202110b Mega Better
We tested the 202110b build against its predecessor (202110a). Here are the areas where it truly excels:
One of the most significant shifts in this release was the visible commitment to quality. Embarcadero focused heavily on addressing customer-reported bugs in the core VCL and FMX frameworks. The "quality" window—literally and metaphorically—felt wider and more transparent.
Fixes ranged from memory leaks in third-party component integration to edge-case compiler bugs that had plagued specific architectures. This focus on "under the hood" fixes is exactly why the community affectionately dubs this a "Mega Better" release.
The nickname "Mega" isn't an official Embarcadero marketing term; it’s a sentiment born from the community. Why? Because v28.0.42642.6927 delivered something developers crave above all else: stability.
While the initial 10.4 release introduced the much-loved "Managed Records," it had some rough edges. The 10.4.2 update polished the compiler and the IDE runtime to a mirror shine. Developers reported significantly fewer crashes, faster load times, and a smoother design-time experience. For teams working on massive codebases, this reliability translates directly to billable hours saved.

Note: I interpret the phrase “delphi 202110b mega better” as a request for a comprehensive examination of the Delphi 2021 Release 2 (often referred to by build/yearing like 2021.10 or 2021.10b) family, focusing on what made that release substantially better (“mega better”) compared with prior releases: key improvements, tooling, language/runtime changes, IDE and toolchain upgrades, platform support, migration considerations, and recommended developer actions. Below I provide a structured, detailed, and practical write-up aimed at Delphi developers, engineering leads, and teams evaluating or migrating to this release.
Cross-platform development is Delphi’s superpower. 202110b introduces a "Delta Compilation" mechanism for FMX styles.
No honest piece about Delphi can ignore the wounds. The community is smaller than it once was. Young developers learn JavaScript, not Pascal. The tooling, though improved, still shows scars of its Borland ancestry: project files that merge poorly in Git, a VCL designer that predates web standards, a learning curve that rewards patience over immediacy.
2021.10b is “mega better” for the initiated. For the newcomer, it can feel like a time capsule — powerful, but foreign. And yet, therein lies a strange beauty. In an industry that rewrites everything every 18 months, Delphi offers continuity. Your code today will outlive the next three frameworks. Your binary will run on Windows 11 as it did on Windows 7.
