TattooMate 1.3.7.6 – More stable license check & form refinements

TattooMate 1.3.7.6 released

Version 1.3.7.6 does not bring "buzzword features" – it brings targeted technical improvements and clean detail work throughout the system.


🔐 License check technically overhauled

The license logic has been restructured internally:

  • Domain-based cache instead of a global in-memory cache
  • Inflight lock to prevent parallel duplicate checks
  • Clean separation between successful TTL cache and error TTL

What does this mean in practice?

When multiple requests arrive simultaneously (e.g. after a restart or under load), the license is not checked multiple times in parallel. Instead, only one request goes to the license API and all other requests wait for the result.
This reduces unnecessary API calls and prevents race conditions.

Additionally, errors are only cached briefly, while successful checks continue to use the regular TTL.
Temporary API issues no longer block the system longer than necessary.

In short: more stable, more robust, more predictable.


⏱ Timeout handling cleaned up

The fetch timeout in the license and version check has been unified.
Redundant clearTimeout calls have been removed and the internal structure is now more consistent.

No visible feature – but cleaner code and less potential for errors.


🖊 Tattoo placement is now a required field

The tattoo form now requires customers to specify where the tattoo will be placed.

Why?

Because it is relevant in practice – both for documentation and for proof of work.
Partial information helps nobody, neither the studio nor the customer.


📧 SMTP test email phrased more clearly

The test email for SMTP settings now contains a clear message:

If this email arrives, the configuration is correct.

No more guessing whether it might have been a coincidence.


🎨 UI refactor: consistent input styles

In all form modules (Tattoo, Piercing, Cosmetic, Tooth), inputs without rounded borders have been aligned to the existing design system.

Goal:

  • consistent visual language
  • uniform appearance across all input fields
  • no more style mixing between modules

Not a big feature – but exactly these details are what keep software clean long-term.


Summary

1.3.7.6 is a stability update.
Less technical ambiguity, cleaner license logic, more consistent interface.

No show – just substance.

More updates to follow.
