feat(pyproject): release v1.7.0 — Python pyproject.toml version bump

Add internal/pyproject package with ReadVersion and WriteVersion for
pyproject.toml files. Reads [project].version (PEP 621) first, then
falls back to [tool.poetry].version. Section boundaries are detected
via TOML's rule that headers always start at the beginning of a line
(\n[ pattern), so inline arrays with [ characters don't interfere.

Config follows the established multi-value pattern:
- python.pyproject_toml: single path (opt-in, no default)
- python.pyproject_tomls: list for monorepos (overrides single)
- --pyproject flag overrides pyproject_toml and clears pyproject_tomls

100% per-package statement coverage maintained across all 14 packages;
FuzzReadVersion and FuzzWriteVersion added per fuzzing guidelines.

 Format: [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
 
+## [1.7.0] - 2026-07-12
+
+### Added
+
+- **Python `pyproject.toml` support** — new `internal/pyproject` package; reads `[project].version` (PEP 621) first, then `[tool.poetry].version` (Poetry); original formatting preserved on write; `regexp.QuoteMeta` ensures safety with dot-containing version strings
+- **`python.pyproject_toml` / `python.pyproject_tomls` config** — opt-in, no default; `pyproject_tomls` list overrides `pyproject_toml` for monorepos; follows the established multi-value pattern (Maven, Node, Gradle)
+- **`--pyproject <path>` flag** — overrides `python.pyproject_toml` and clears `pyproject_tomls`; shown in verbose config table as `python.paths`
+- **`FuzzReadVersion` / `FuzzWriteVersion`** in `internal/pyproject` — 100% per-package statement coverage maintained across all 14 packages
+
+## [1.6.3] - 2026-07-11
+
+### Added
+
+- **Logo** — `docs/static/images/releaser-logo-1024.png` (1024×1024) set as Geekdoc site header logo via `geekdocLogo`; 128×128 version added to README above the release badge
+
+### Fixed
+
+- **`.gitignore` over-matching** — `releaser-*` was catching files inside `docs/static/images/`; anchored to `/releaser-*` so only root-level release binaries are excluded
+
+### Changed
+
+- **`docs/hugo.toml` `baseURL`** — set to `https://releaser.k3nny.fr/` (was `"/"`)
+
+## [1.6.2] - 2026-07-11
+
+### Changed
+
+- **`task ci` now runs `go tool staticcheck ./...`** — runs between `go vet` and `go test`; matches the step already present in the Gitea CI workflow
+
+### Fixed
+
+- **SA4006 in `TestLatestTagTagsIterFails`** — `err` from `gogit.PlainOpen` was assigned then immediately overwritten without being read; added the missing `if err != nil { t.Fatalf(...) }` check
+
+## [1.6.1] - 2026-07-11
+
+### Fixed
+
+- **CI root-permission failures** — four tests that used `os.Chmod` to force error paths were failing in Docker CI (which runs as root, where chmod has no enforcement effect); each now skips with `os.Getuid() == 0`; the gitutil test had broken skip logic that only fired if `Chmod` itself errored — replaced with the same upfront UID check
+

 Standard tools like `semantic-release` are designed for trunk-based development. In a GitFlow setup with versioned release branches (`release/1.1`, `release/1.2`), they either fail to respect the branch's version range or require brittle configuration.
 
 `releaser` is built for this exact workflow: it reads the branch name to pin the `major.minor`, parses Conventional Commits to determine the patch increment, and handles everything from `pom.xml` / `package.json` update to GitLab/GitHub tag and release creation.

+## Python support
+
+The `python` section is opt-in — if omitted, no `pyproject.toml` is touched. `releaser` reads `[project].version` (PEP 621) first; if not found it falls back to `[tool.poetry].version`. The original file formatting is preserved on write.
+
+```yaml
+python:
+  pyproject_toml: "pyproject.toml"
+```
+
+Use `pyproject_tomls` for monorepos:
+
+```yaml
+python:
+  pyproject_tomls:
+    - "pyproject.toml"
+    - "packages/cli/pyproject.toml"
+    - "packages/lib/pyproject.toml"
+```
+
+The `--pyproject <path>` CLI flag sets a single path and clears `pyproject_tomls`.
+
 ## Gradle support
 
 The `gradle` section is opt-in — if omitted, no build file is touched. Both Groovy DSL (`version = '1.2.3'`) and Kotlin DSL (`version = "1.2.3"`) are supported; the original quote style is preserved on write.
