v0.8.4 - Early mutation typo fix

[0.8.4] - 2026-05-21

Fixed

• Optimised shell history matching pool logic within functions/history to resolve early mutation typos (e.g., ccd instead of cd). Implemented a deterministic single-character prefix filter that preserves argument matching inside trailing directories while preventing wide-pool history pollution from unrelated commands.

Known Issue

• Mend will not be able to match a typo and suggest fix if it happens at the very first character. This is a sacrifice that has been well thought through during testing to limit unrelated outputs in the fuzzy-search.

v0.8.3: Git Deployment Wizard & History Assistant Rewrite

[0.8.3] - 2026-05-18

Added

• New interactive deployment module (mend -git) featuring a fully non-destructive fzf TUI for repository initialization, remote tracking layout configuration, commit compilation, and annotated release tagging.
• Automated next-point release version prediction inside the Git deployment tag selection stream.
• Comprehensive user documentation entries for the Git deployment tool inside the README usage and help systems.

Fixed

• Re-architected the history assistant (mend -h) to eliminate duplicate suggestion entries by dropping parallel array appending loops.
• Replaced strict fuzzy query locking with a lightweight two-character prefix constraint, dropping background command noise while resolving hidden match bugs for directory path and package manager typos.
• Corrected terminal buffer flooding and Zsh 1-index subscript failures within the proximity sorting pipeline.
• Resolved execution path calculation failures across standard desktop workspaces by dynamically targeting context layout blocks inside the master wrapper.

[0.8.2] - 2026-05-14

Added

• Expanded hardware.db with legacy support for NVIDIA NVS 3100M and Intel 5 Series chipset components.

v0.7.0: Smarter history search and automatic typo cleanup

[0.7.0] - 2026-04-14

Added

• New mend -h flag to trigger an interactive history-based correction mode.
• Automatic history purging: selecting a correction now removes all instances of that specific typo from the Zsh history file and internal buffer.
• Integrated fzf scoring with a specific history scheme to better rank long command strings and complex arguments.

Improved

• Refactored history search to use a prefix-based fuzzy match, significantly reducing noise from unrelated commands.
• Optimised history handling for large files (20,000+ entries) by using native Zsh buffer management.
• Enhanced typo detection by utilising the full string length for weighted ranking in the suggestion menu.

Fixed

• Resolved an issue where repeated typos would persist in the history list even after being corrected.
• Fixed a bug causing history inflation when syncing buffers across multiple terminal sessions.
• Corrected a scoring scheme error in fzf to ensure compatibility with standard Arch Linux installations.

v0.6.0 The Cross-Distro Expansion

[v0.6.0] - 2026-04-06

Added

• Distro-Agnostic Core: Full rewrite to support Arch (pacman), openSUSE (zypper), Fedora (dnf), and Ubuntu/Mint (apt).
• Dynamic Driver Setup: Automatic package manager detection and path mapping for locks, queries, and installs.
• Unified Knowledge Base: Migrated error descriptions and Wiki links into a modular MEND_KB associative array for all supported distributions.
• Agnostic Library Search: New provider extraction logic that handles different table formats across apt-file, zypper, and dnf repoquery.
• The Janitor (Multi-Distro): Added orphan cleanup support for apt autoremove, dnf autoremove, and zypper packages --unneeded.

Fixed

• Table Parsing: Implemented robust header-skipping and column-index logic to handle padded output from Zypper and DNF.
• Clean Selection: Added xargs and Zsh parameter stripping to ensure package names are passed to the installer without accidental spaces or colons.

Changed

• Documentation: Simplified the README to focus on readable instructions and universal requirements.

Full Changelog: v0.5.0...v0.6.0

v0.5.0 Shared Library Restoration & Version Fallback

[v0.5.0] - 2026-03-27

Added

• Shared Library Repair: New detection engine for error while loading shared libraries.
• Intelligent Version Fallback: Implemented automatic base-name searching (e.g., libalpm.so.13 → libalpm.so) to resolve rolling-release version increments.
• Physical File Verification: Added a pre-search check for files in /usr/lib/ and /lib/ to confirm a library is truly missing before suggesting repairs.
• Database Age Nudge: Integrated a check for pacman -Fy database metadata. Mend now warns if the sync database is missing or older than 7 days.
• Arch Wiki Shortcut: Added [w] keybinding to the library provider menu, linking directly to System Maintenance documentation.

Fixed

• Search Noise: Filtered out "private" bundled libraries (e.g., /opt/teamspeak3/) by prioritising system-wide library paths in the provider search.
• String Parsing: Replaced brittle awk/sed pipes with native Zsh parameter expansion for safer package name extraction.
• FZF Preview: Corrected the preview command to ensure pacman -Si always receives a clean package name string.

Changed

• Internal Logic: Optimised the library search to use a single while loop with internal Zsh splitting, reducing subshell overhead.
• README: Migrated full version history to CHANGELOG.md and streamlined the main documentation for better readability.

Key Highlights:

• Wiki Integration: Instant access to troubleshooting guides via the [w] key during any fix prompt.
• KB Engine: Unified metadata handling for Database Locks, PGP verification, and Mirror failures.
