Notes

Title of the patch: Security update for zk

Description of the patch: This update for zk fixes the following issues: Changes in zk: - Update to version 0.15.6: * Parse links to notes in frontmatter * Set filters for lsp completion items from the config * Set a note's modification time in frontmatter and allow for custom key naming for both creation and modification keys * Indexing made significantly more performant * Support filtering by date and time with "<date> <time>" instead of <date>T<time> only * Exclude globs now prune matching directories from indexing, improving speed of indexing - Update to version 0.15.5: * List, edit and filter for broken links with --broken-links * Update strftime package, supporting %g and %G formats in the {{format-date}} helper * Option to append links to selected text, instead of replacing * Paths with ~ and env variables no longer error when passed to --notebook-dir and --working-dir * Guard LSP against unnecessary erroring on missing textDocument/definition capabilities - Update to version 0.15.4: * fix "jump to definition" follows wrong link * zk config --list <object> (by @andrebauer, 484) * Ignore commented links for LSP diagnostics. Use an AST to parse files, fixing * other similar edge cases. * Links in markdown footnotes now included in :ZkLinks * Indexing notebook now 35% and 74% faster for full and incremental indexing * respectively * Stop crashing lsp server when server received textDocument/completion request with out of range parameters. * lsp: Provide completion after [[ on lines with multi-byte characters * Prevent crash in LookForward when the parameters is out of characters number. - Update to version 0.15.2 * Find notes with missing backlinks using zk list --missing-backlink * LSP diagnostic for missing backlinks when other notes link to current note without reciprocal links * Code action to add missing backlinks * LSP diagnostic for self-referential links * Release tarballs now output the program version * Config path can be set with $ZK_CONFIG_DIR * bump deps: golang.org/x/crypto v0.45.0 fixes CVE-2025-58181 - Update to version 0.15.0 * fixed LSP crashes when editing code fences and/or working in text files with code fences * new feature to set a group path "by name", in that any directory with the same name can share the same group rules, no matter how deep in the notebook. See references below. - Update to version 0.14.2 * Path in .zk/config.toml for the default note template now accepts UNIX "~/paths" * Find notes without tags with zk list --tagless * fix: LSP ignores magnet links as links to notes * fix: Note titles with double quoted words no longer break json output * fix: Grammar in error output * fix: Group rules could not be nested

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
