Also\n    upgraded GitHub Actions imports to fix CI failures.\n  * Fixed an unaligned pointer dereference issue on select architectures.\n  * Fixes to Jenkins CI pipeline.\n  \n\n- New Version: 1.3.1:\n\n  * CVE-2024-20380: Fixed a possible crash in the HTML file parser\n    that could cause a denial-of-service (DoS) condition.\n  * Updated select Rust dependencies to the latest versions.\n  * Fixed a bug causing some text to be truncated when converting\n    from UTF-16.\n  * Fixed assorted complaints identified by Coverity static\n    analysis.\n  * Fixed a bug causing CVDs downloaded by the DatabaseCustomURL\n  * Added the new 'valhalla' database name to the list of optional\n    databases in preparation for future work.\n\n- New version: 1.3.0:\n\n  * Added support for extracting and scanning attachments found in\n    Microsoft OneNote section files. OneNote parsing will be\n    enabled by default, but may be optionally disabled.\n  * Added file type recognition for compiled Python ('.pyc') files.\n  * Improved support for decrypting PDFs with empty passwords.\n  * Fixed a warning when scanning some HTML files.\n  * ClamOnAcc: Fixed an infinite loop when a watched directory\n    does not exist.\n  * ClamOnAcc: Fixed an infinite loop when a file has been deleted\n    before a scan.\n\n- New version: 1.2.0:\n\n  * Added support for extracting Universal Disk Format (UDF)\n    partitions.\n  * Added an option to customize the size of ClamAV's clean file\n    cache.\n  * Raised the MaxScanSize limit so the total amount of data\n    scanned when scanning a file or archive may exceed 4 gigabytes.\n  * Added ability for Freshclam to use a client certificate PEM\n    file and a private key PEM file for authentication to a private\n    mirror.\n  * Fix an issue extracting files from ISO9660 partitions where the\n    files are listed in the plain ISO tree and there also exists an\n    empty Joliet tree.\n  * PID and socket are now located under /run/clamav/clamd.pid and\n    /run/clamav/clamd.sock .\n  * bsc#1211594: Fixed an issue where ClamAV does not abort the\n    signature load process after partially loading an invalid\n    signature.\n\n- New version 1.1.0:\n\n  * https://blog.clamav.net/2023/05/clamav-110-released.html\n  * Added the ability to extract images embedded in HTML CSS\n    \u003cstyle\u003e blocks.\n  * Updated to Sigtool so that the '--vba' option will extract VBA\n    code from Microsoft Office documents the same way that\n    libclamav extracts VBA.\n  * Added a new option --fail-if-cvd-older-than=days to clamscan\n    and clamd, and FailIfCvdOlderThan to clamd.conf\n  * Added a new function 'cl_cvdgetage()' to the libclamav API.\n  * Added a new function 'cl_engine_set_clcb_vba()' to the\n    libclamav API.\n- bsc#1180296: Integrate clamonacc as a service.\n- New version 1.0.1 LTS (including changes in 0.104 and 0.105):\n  * As of ClamAV 0.104, CMake is required to build ClamAV.\n  * As of ClamAV 0.105, Rust is now required to compile ClamAV.\n  * Increased the default limits for file and scan size:\n    * MaxScanSize: 100M to 400M\n    * MaxFileSize: 25M to 100M\n    * StreamMaxLength: 25M to 100M\n    * PCREMaxFileSize: 25M to 100M\n    * MaxEmbeddedPE: 10M to 40M\n    * MaxHTMLNormalize: 10M to 40M\n    * MaxScriptNormalize: 5M to 20M\n    * MaxHTMLNoTags: 2M to 8M\n  * Added image fuzzy hash subsignatures for logical signatures.\n  * Support for decrypting read-only OLE2-based XLS files that are\n    encrypted with the default password.\n  * Overhauled the implementation of the all-match feature.\n  * Added a new callback to the public API for inspecting file\n    content during a scan at each layer of archive extraction.\n  * Added a new function to the public API for unpacking CVD\n    signature archives.\n  * The option to build with an external TomsFastMath library has\n    been removed. ClamAV requires non-default build options for\n    TomsFastMath to support bigger floating point numbers.\n  * For a full list of changes see the release announcements:\n    * https://blog.clamav.net/2022/11/clamav-100-lts-released.html\n    * https://blog.clamav.net/2022/05/clamav-01050-01043-01036-released.html\n    * https://blog.clamav.net/2021/09/clamav-01040-released.html\n- Build clamd with systemd support.\n\n* CVE-2023-20197: Fixed a possible denial of service vulnerability in\n  the HFS+ file parser.
