v2.19.3

Bugs fixed

• Fixed a bug where using codeql database import to combine multiple non-empty databases may produce a corrupted database. (The bug does not affect using codeql database finalize --additional-dbs to combine multiple databases.)
• Fixed a bug where uses of a QlBuiltins::ExtensionId variable that was not bound to a value could be incorrectly accepted in some cases. In many cases, this would result in a crash.
• CodeQL would sometimes refuse to run with more than around 1,500 GB of RAM available, complaining that having so much memory was "unrealistic". The amount of memory CodeQL is able to make any meaningful use of still tops out at about that value, but it will now gracefully accept that so large computers do in fact exist.
• Fixed a bug in command-line parsing where a misspelled option could sometimes be misinterpreted as, e.g., the name of a query to run. Now every command-line argument that begins with a dash is assumed to be intended as an option (unless it comes after the -- separator), and an appropriate error is emitted if that is not a recognized one.

Miscellaneous

• The CodeQL Bundle is now available as an artifact that is compressed using Zstandard. This artifact is smaller and faster to decompress than the original, gzip-compressed bundle. The CodeQL bundle is a tar archive containing tools, scripts, and various CodeQL-specific files.

For more information about the changes included in this release, see the CodeQL CLI changelog.

You can download either the codeql-PLATFORM.zip for your platform, or the generic codeql.zip which contains binaries for all supported platforms. Please ignore the additional "source code" downloads below the .zip artifacts.

This release is compatible with the CodeQL language packs from github/codeql@codeql-cli/v2.19.3.
