release: v0.5.0 — establish Odoo 14.0 branch (ITSulu production target)

Seed the 14.0 series branch from the 17.0 baseline:
- .odoo-series = 14.0; Dockerfile FROM odoo:14.0; manifest 14.0.0.5.0
- PORTING.md tracks the Odoo-14 checklist (biggest delta: mail templates
  must revert to Odoo 14's Jinja2 syntax; render API differs)
- README retargeted to 14.0 with porting-in-progress notice
- CHANGELOG v0.5.0 entry

NOTE: seeded from 17.0 — the Odoo-14 port is NOT yet verified (PORTING.md).
Not deploy-ready on the production 14.0 instance until the suite is green there.

+## v0.5.0 — 2026-05-30
+
+Sets up support for **multiple Odoo Community versions**, each on its own branch — the same
+model the Odoo project itself uses. We initially target **Odoo 19.0** (the latest stable) and
+**Odoo 14.0** (the version ITSulu runs in production).
+
+### Added
+
+- **Per-Odoo-version branches.** The addon now lives on a branch per Odoo release — `19.0`
+  and `14.0` — so each can track the API differences of its Odoo version independently. Check
+  out the branch that matches your Odoo install.
+- **Version tooling is Odoo-aware.** The release helper (`bump-version.sh`) now reads which
+  Odoo series a branch targets and stamps the addon and release tags accordingly
+  (e.g. `19.0-v0.5.0`, `14.0-v0.5.0`), so one product version can ship on several Odoo versions.
+- A `PORTING.md` on each version branch tracks what still needs checking for that Odoo release.
+
+### Notes
+
+- This `14.0` branch is the target for the **ITSulu production** instance. It is **seeded from
+  the 17.0 codebase**, so the Odoo-14 port is still being completed — most notably the email
+  template must move back to Odoo 14's older Jinja syntax. See `PORTING.md`.
+- Documentation (`README`, `CLAUDE.md` §15) now describes the branch-per-version model.

+# Porting status — Odoo 14.0 branch
+
+This branch targets **Odoo Community 14.0** — the version **ITSulu runs in production**. It was
+**seeded from the 17.0 baseline** and the Odoo-14 porting is tracked here. Until every item is
+verified, treat this branch as **work in progress** — do not deploy to the production 14.0
+instance unverified.
+
+> The product feature set is the same across all Odoo branches; only the Odoo-API-specific code
+> differs. Odoo 14 is **older** than the 17.0 baseline, so several things move *backwards*.
+> See `CLAUDE.md` §15 for the branch model and §11.5 / §12 for version-specific gotchas.
+
+## Series markers (done)
+
+- [x] `.odoo-series` = `14.0`
+- [x] `Dockerfile` base image = `odoo:14.0`
+- [x] manifest version prefix = `14.0.` (via `bump-version.sh`)
+
+## API porting checklist (verify on a real Odoo 14.0 instance)
+
+- [ ] **Mail template syntax — REVERT to Jinja2.** Odoo 14 renders `mail.template` with Jinja2
+      (`${object.blog_post_id.name}`, `% if`, `% for`), **not** the qweb `<t t-out>` used on 17.0.
+      The 17.0 template in `data/mail_template_data.xml` must be converted back to Jinja for 14.0.
+- [ ] **Mail render API.** 14.0 uses `template.render_template(...)` / `_render_template(...)`,
+      not 17.0's `_render_field`. Update `blog_generation_log.send_notification_email` + tests.
+- [ ] `blog.post` body field name on 14.0 (the 17.0 baseline writes `content` — confirm 14.0).
+- [ ] Python 3.6–3.8 only — remove any 3.9+ syntax (dict `|` merge, `str.removeprefix`, etc.).
+- [ ] `@api.model_create_multi`, `name_get`, and other ORM signatures valid on 14.0.
+- [ ] View/RELAXNG validation for 14.0 (attrs/states syntax differs from 17.0).
+- [ ] `ir.cron` + mail data XML formats.
+- [ ] Full test suite green on a 14.0 template DB (K8s job, §8, base image `odoo:14.0`).
+- [ ] pytest-odoo / pytest-bdd versions compatible with the 14.0 Python.
+
+## How to work this branch
+
+1. Stand up a 14.0 template DB (mirror §8, base image `odoo:14.0`).
+2. Start with the mail template (Jinja revert) and the render API — those are the biggest deltas.
+3. Run the suite, fix one Odoo-API difference at a time.
+4. Record each gotcha in `CLAUDE.md` §12 tagged with the series.
+5. When green, cut a release on this branch (`bump-version.sh` → tag `14.0-vX.Y.Z`).
