CLion 2019.3.1 Critical Bug-fix Update

Last week we released CLion 2019.3. Unfortunately, it was affected by several unpleasant issues. We’ve investigated all the reports from our users and promptly addressed the discovered problems.

CLion 2019.3.1 (build 193.5233.144) is now available for download from our website, via the Toolbox App, or via snap (for Ubuntu). A patch update will be available shortly.


This update contains the following fixes:

  • Language engine:
    • A problem with randomly occurring red code and an incorrect suggestion to import user classes from the std namespace turned out to be an issue with the missing include file (CPP-18270 and the related CPP-18246, CPP-18247CPP-18280).
    • Completion of standard library symbols in the global namespace is now working correctly in Clangd (CPP-18249).
    • Various fixes preventing the Clangd-based engine from crashing were introduced.
  • Remote development:
    • A mechanism of synchronizing headers in background was recently enabled by default, and it turned out to cause massive delays on loading CMake projects in many cases (e.g. CPP-18277). We’ve reverted it for now until we can come up with a better solution.

Our team appreciates all the valuable feedback the community provided after the release and sincerely apologizes for any inconvenience caused.
