+## [1.0.0] - 2026-07-04
+
+First tagged release. mkhint manages slackrepo hint files: create/update hints,
+nvchecker-driven update checks, phantom-dep stripping for -current, and a
+listing/review workflow.
+
+### Changed
+- **Breaking:** the hint-version flag is now `-V` / `--set-version`. `-v` /
+  `--version` now prints the tool's own version and exits.
+
+### Added
+- `-v` / `--version` prints `mkhint X.Y.Z`.
+- The `--help` header shows the version.
+- `-l` colors the newer version cell green and adds a `DelReq` column.

 ## Configuration
 
+The tool version is a `readonly MKHINT_VERSION` constant near the top of `mkhint`. `-v` / `--version` prints `mkhint <version>` and exits; the `--help` header shows it too. Setting a hint's version string uses `-V` / `--set-version` (renamed from the old `-v`). Project follows SemVer; releases tagged `vX.Y.Z`, bump `MKHINT_VERSION` in the tagging commit. See `CHANGELOG.md`.

 ## Key Behaviors
 
 - `--hintfile` update: backs up to `.bak`, replaces old version string globally via `sed`, re-downloads both URLs to recalculate MD5 checksums. Skips download if value is `UNSUPPORTED` or `UNTESTED`.
-- `--new` with existing `.info`: copies `.info` as template, strips `PRGNAM`, `HOMEPAGE`, `MAINTAINER`, `EMAIL`, comments out `REQUIRES`, sets `ARCH="x86_64"`. Keeps `VERSION` from `.info`. If `-v` given, updates version string and recalculates checksums. Also appends an nvchecker `[section]` to the config, auto-detecting github/pypi source or providing a commented stub.

If `-V` given, updates version string and recalculates checksums. Also appends an nvchecker `[section]` to the config, auto-detecting github/pypi source or providing a commented stub.
 - `--new` when hint already exists: backs up old, creates empty skeleton.
-- `--hintfile` with no `-v`: queries nvchecker for latest version, shows current vs. latest, prompts to accept/override/decline. After accepting, runs `nvtake` to sync nvchecker's keyfile.
+- `--hintfile` with no `-V`: queries nvchecker for latest version, shows current vs. latest, prompts to accept/override/decline. After accepting, runs `nvtake` to sync nvchecker's keyfile.
 - `--list` / `-l`: lists hints with `HintVer`/`SBOVer` plus a `DelReq` column (before `Created`) showing `✓` when the hint has a populated `DELREQUIRES` (detected via `grep '^DELREQUIRES="..*"'`, padded with `_pad_glyph` so the multibyte glyph stays aligned). Hints with no `VERSION` are skipped (and excluded from the total). Version columns are 22 wide to fit long version strings. Coloring: rows where the two versions are byte-equal get the whole row yellow (and populate `MATCHED_PKGS` for `-R`); when they differ, `sort -V` picks the newer side and only that version cell is green (version strings are pre-padded to 22 before the color wrap so the escape bytes don't break alignment); an absent/empty `SBOVer` leaves the row plain. Color only on a TTY (or `MKHINT_FORCE_COLOR`); plain when piped. Legend `(yellow row = versions match; green = newer side)` prints when any row matched. With package names (`-l foo bar`), the table is skipped and each named hint is shown side by side with its `.info` via `_show_hint_diff` (shared with `--review`); missing hint → exit 2.
 - `--review` / `-R`: with no package args, iterates only the matched (highlighted) hints. With explicit package names (`-R foo bar`), reviews each named hint regardless of version match (existence required: missing hint → exit 2). For each, shows the hint side-by-side with its `.info` (`git diff --no-index` if git present, else `diff -y`), then prompts `[K]eep / [D]elete / [S]kip` (default Keep). Delete removes the hint and its `.bak` via `_remove_hint`. Prints a deleted/kept summary counting hints actually reviewed. `-l` and `-R` combine: `-lR` shows the table first, then reviews. Bare `-R` with no matches → "nothing to review", exit 0. Per-hint logic lives in `_review_one_hint`; `review_hint_files` drives it from either the named list or `MATCHED_PKGS`.
-- `--check` / `-C`: runs nvchecker for all (or named) hints. With exactly one explicit package it uses `nvchecker -e <pkg>` to skip scanning the whole config; with two+ packages or no args it does one full scan. (`--hintfile` with no `-v` also queries via `nvchecker -e <pkg>`.) reports outdated packages with current → latest versions, prompts per-package to update, applies updates with `nvtake`, then prompts single `slackrepo update` for all updated packages. Hints with no `[pkg]` section in `nvchecker.toml` are collected and, after the scan, a single prompt offers to populate the config via `add_nvchecker_section` (github/pypi autodetect, else stub); on accept it prints a "review and re-run" message and stops the run without applying updates. Packages whose `.info` is not found in `REPO_DIR` are skipped. Upstream versions are normalized via `_normalize_version` (`-` → `_`) before comparing and before storing, so a dashed upstream version like `2026-06-02` matches the packaged `2026_06_02` (SlackBuild versions cannot contain `-`) and updates are written in the underscore form. The same normalization applies to `--hintfile` with no `-v`. `nvtake` still uses nvchecker's own raw keyfile value.

 - `--no-dl` / `-N`: downloads and recalculates checksums as normal, then appends `NODOWNLOAD=yes` after `MD5SUM_x86_64=`. Works with `--hintfile` or `--new`. Error if used alone.
-- `--fix-current` / `-F`: bulk sweep. Loads `PHANTOM_DEPS_FILE`, scans every `.info` in `REPO_DIR`, and for each package whose REQUIRES contains a phantom dep, ensures its hint carries the matching `DELREQUIRES`. No existing hint → create a minimal `DELREQUIRES="..."` file. Existing hint → back up to `.bak` and union the phantom deps into its `DELREQUIRES` line (dedup), leaving all other content untouched. Idempotent: if the deps are already present, the file is left alone and no `.bak` is written. No per-package prompts, safe under `set -e`. Mutually exclusive with `-v`/`-f`/`-n` (exit 1). Empty/missing list → "Nothing to do", exit 0. Helpers: `load_phantom_deps`, `phantom_deps_in_info`, `merge_delrequires`, `fix_current`.

 - `--delete` / `-d`: removes hint file and `.bak` if present. Accepts multiple package names. Exits 2 on first missing file.

+## Versioning
+
+This project follows [Semantic Versioning](https://semver.org/). Commits use [Conventional Commits](https://www.conventionalcommits.org/): `feat:` bumps the minor version, `fix:` the patch version, and a `!` / `BREAKING CHANGE` the major version. Releases are tagged `vX.Y.Z`; the version is stored in `MKHINT_VERSION` in the `mkhint` script. `mkhint -v` (or `--version`) prints it. See [CHANGELOG.md](CHANGELOG.md).
