• 2020.09.09 Blog by David Millington Problem with IDE Plugins in RAD Studio 10.4.1

  • IDE Plugins that have custom docked windows need to be recompiled with 10.4.1 as binary compatibility was broken.
  • Its recommended to uninstall IDE plugins before upgrading to 10.4.1, and then re-install the 10.4.1 versions of your IDE plugins.

• 2020.09.09 Blog by Marco Cantu Some Delphi 10.4.1 Features: Improved LSP and TLightweightMREW

• 2020.09.08 Blog by Marco Cantu New TLightweightMREW Record in RAD Studio 10.4.1

  • The new TLightweightMREW record wraps native POSIX APIs, and it is a better replacement in most cases.
  • It has been implemented as a managed record to further reduce the need of creating and freeing it.
  • Supported features across all platforms:
    • If any thread holds a read lock then any other thread can also acquire a read lock while no one can acquire a write lock.
    • If any thread holds a write lock then no thread can acquire a read nor a write lock.
    • If a thread holds a read lock, it can acquire another read lock again before the first read lock is released (recursion).
    • If a thread holds a write lock, it cannot acquire another write lock
  • The following behavior depends on the operating system:
    • If at least one reader is always active, a writer may never get the lock (starvation)
    • If the same thread tries to recursively acquire a write lock two times, the application will deadlock on Windows but raise an exception on POSIX systems.

• 2020.09.07 Blog by David Millington New for Delphi Code Insight in 10.4.1

  • Code Completion includes items that start with your typed text, but also that contains your typed text. Now this text is underlined by default in the list of results (see image below)
  • Four new settings added to Insight Options (see image below):
    • List all symbols that start with the filter first
    • Select shortest matching symbol
    • Filter text is underlined
    • Show symbols that contain filter
  • To reproduce Code Insight behavior in previous releases of Delphi, keep the first setting on and turn the rest off.

Some 10.4.1 issues to review

• 2020.09.30 Blog by Marco Cantu Addressing the Problem of the Missing dbxConnections.ini File
• Review blog post on problem with IDE plugins with 10.4.1
• RSP-30820 Fail to load package with LIBSUFFIX AUTO
  • The issue occurs if there is no project file (just the dpk file with the new {$LIBSUFFIX AUTO} define) and you open this DPK file into the IDE. The IDE thinks the actual suffix is "AUTO". If instead you add the {$LIBSUFFIX AUTO} via project options, it works as expected.
• RSP-30755 VCL Font property in TSpeedButton not working
• RSP-30639 VCL Styles excess flicker on resize
• RSP-30825 VCL Style not applied to TTitleBarPanel
• RSP-30845 FMX TMemo insert text different than 10.3.3
• RSP-30685 Cannot install different version of Indy
