  apt (2.8.3) noble; urgency=medium

  * Revert increased key size requirements from 2.8.0-2.8.2 (LP: #2073126)
    - Revert "Only install 00-temporary-rsa1024 for >=2.7.6 and improve comment"
    - Revert "Only warn about <rsa2048 when upgrading from 2.7.x to 2.8.x"
    - Revert rsa1024 to warnings again
    This leaves the mechanisms in place and no longer warns about NIST curves.
  * Fix keeping back removals of obsolete packages; and return an error if
    ResolveByKeep() is unsuccessful (LP: #2078720)
  * Fix buffer overflow, stack overflow, exponential complexity in
    apt-ftparchive Contents generation (LP: #2083697)
    - ftparchive: Mystrdup: Add safety check and bump buffer size
    - ftparchive: contents: Avoid exponential complexity and overflows
    - test framework: Improve valgrind support
    - test: Check that apt-ftparchive handles deep paths
    - Workaround valgrind "invalid read" in ExtractTar::Go by moving large
      buffer from stack to heap. The large buffer triggered some bugs in
      valgrind stack clash protection handling.
