MyTraL 1.56.0

This MyTraL minor release brings:

Added

• Added a Flatpak distribution (fitness.mytral.Mytral). The package runs the local
  server and opens the UI in the default browser.
  Athlete data are stored outside of the sandbox in the standard MyTraL directory.
• Added Distro Tarball GHA workflow that builds the upstream tarball in
  rel/<major.minor.patch> branches targeting main.
• Added Distro Snap GHA workflow that builds the Snap package in
  rel/<major.minor.patch> branches targeting main.
• Added Distro Windows GHA workflow that builds the Windows installer and ZIP archive
  on a Windows runner in rel/<major.minor.patch> branches targeting main.
• Added Distro Flatpak GHA workflow that builds the Flatpak bundle in
  rel/<major.minor.patch> branches targeting main.
• Added distro-win-zip Makefile target that packages the Windows desktop executable
  into a ZIP archive (distro/windows/mytral-<version>.exe.zip).

Changed

• Removed the Waitress WSGI server from the desktop edition. The desktop app serves
  a single local, so it now uses Flask's built-in threaded server - this removes
  a dependency and simplifies installation and packaging across Snap, PPA,
  and the Windows installer.
• Updated bleach from 6.3 to 6.4.
• Updated cryptography from 46.0 to 48.0.
• Updated msgpack from 1.0 to 1.2.
• Updated pytest (dev) from 8.4 to 9.0.

Documentation

• Documented Flatpak install and build.
• Documented Snap build.

Fixed

• Fixed distro-win-installer Makefile target which depended on the Linux targets.

MyTraL 1.55.0

This MyTraL minor release brings:

Changed

• Switched from Python 3.11 to Python 3.12. The main reason is that Snap 22 runtime
  had Python 3.10 and Snap 24 runtime has Python 3.12. New Python constructs - like
  type, override, and T - will be incorporated as I go.

Added

• Added improved Windows installer make targets and build artifacts.
• Added Ubuntu resolute to Launchpad PPA.

Fixed

• Fixed "missing waitress" server in the MyTraL installation from PPA apt log.

Documentation

• Banner improved by the switch to MyTraL WWW palette.

MyTraL 1.54.0

This MyTraL minor release brings:

Fixed

• Fixed and refactored Snap distribution builder to have snapcraft.io on repository
  paths required by snapcraft.io, use host's vs. container's resources correctly,
  and avoid use of (host) hard-coded paths.

MyTraL 1.53.0

This MyTraL minor release brings:

Added

• Added Ubuntu PPA distribution for Ubuntu via Launchpad (ppa:ultradvorka/sport).
• Added distro-ubuntu-deb Makefile target to build .deb package locally.
• Added Snap package distribution for universal Linux package management. Opens a native
  desktop window via FlaskUI via classic confinement. User data stored in default
  locations.

Fixed

• Fixed elevation chart rendering in the application's analysis page by smoothing
  the GPX points.
• Fixed .deb packaging: Python dependencies are installed into an isolated virtualenv at
  /opt/mytral/venv/ - system Python environment is never polluted.
• Fixed .deb wrapper scripts to export MYTRAL_INCARNATION, MYTRAL_USER_REGISTRATION,
  and MYTRAL_ENABLE_CACHE environment variables for correct desktop startup.

Performance

• Fixed top calendar week navigation which was slooow as it was build on the frontend -
  moved it to the backend.
• Fixed top feed day navigation which was slooow as it was build on the frontend -
  moved it to the backend.

MyTraL 1.50.0

This MyTraL release is very special to me. After years of coding and hacking
together various versions of MyTraL I am moving to a brand-new Git repository on my 50th
birthday.

Sports have been my main hobby for 40 years - I have 30 years of training data scattered
across everything from paper logs to MyTraL. Today, I’m starting a fresh chapter - free
from hacks, sensitive data and the "sins of my youth."

Channeling Steve Prefontaine energy today - pure heart, max effort, FLOSS execution!

Added

• Added polyline with map background to the activity feed.
• Added rainbow polyline w/ running dot to the activity feed.
• Added elevation chart to the activity feed.
• Added "maximize map" action to the activity view page.
• Added description field to symptoms so that user can specify how to cure such injury
  or illness.
• Added import of Strava bulk user export ZIP archive (activities, GPX/TCX recordings,
  photos).
• Added TCX import (individual files and directory of recordings/archives).
• Added gender field to the athlete profile in order to calculate metrics like TRIMP
  more accurately.
• Added TRIMP calculation and chart to the Progress menu.
• Added FIT directory import - import all FIT files from a local directory in one go,
  with automatic conflict detection and parquet generation.
• Bulldozer framework - a multiprocessing-based sandboxed job runner for
  parallelizing CPU-bound import workloads across multiple cores.
• GPX polyline encoding with 2 selectable methods: fast distance-based sampling
  (default) and legacy RDP-based simplification for preview rendering. New GPX polyline
  encoding is ~4000× faster with the new distance-based sampling method - the default
  for all recording import paths.
• Added meta sport taxonomy based lifetime totals insight page.
• Added new cards on the homepage indicating the risk of injury, gear needed service,
  suggested activity and weight balance.
• Added resting HR estimate to the athlete metrics page.

Changed

• Strava API import is not hidden behing feature flag (just inverse condition on FE).
• Refactored Predictions insight page to two pages - Predictions and Analytics.
• Rewritten task manager, tasks and tasks invocation - removed duplicated task manager
  definitions, converged to MyTraL's task manager, typed tasks are used from now on.
• Strava bulk ZIP archive import rewritten with Bulldozer framework for parallel
  photo & recording upload, parquet conversion, and GPX map-data precomputation.
• Polar Precision Performance import rewritten with Bulldozer framework - HRM blob
  upload and parquet generation now run in .

Removed

• Removed Suffer Score from the ActivityEntity and related forms and HTML code.

Fixed

• Fixed blobstore logging message which no longer specifies wrong blob type.
• Polar HRM import conflict resolution no longer fails on missing year-cache entries.
• fit_tool monkeypatch tolerates non-UTF8 bytes in FIT string fields (Garmin
  developer fields), preventing silent parse failures.
• Fixed many problems in the Polar PPP import - from user forgetting to switch
  the activity type, to the source of data (HRM vs. PDD) and the right units.
• Fixed notifications decorator - it's newly tightly coupled w/ the icon.

MyTraL 1.9.0

This MyTraL minor release brings:

Added

• Added import from FIT.
• Added import from GPX - file or directory.
• Added GPX recording management: upload, view metadata, edit name/description/keywords, download, and delete.
• Added storing of recorded data (FIT, GPX, Polar HRM) to Parquet and Polars-based loading/saving.
• Added power zones.
• Added HR zones.
• Added 2D maps rendering for GPX recordings.
• Added athlete performance metrics w/ FTP, aerobic/anaerobic thresholds, ... estimates.
• Added recorded data analytics - ridge/bar/line charts of various metrics.
• Added multi-photo upload support for activities - up to 50 photos per activity.
• Added outfits selection to activity create and update (all) forms.
• Added outfits display to activity detail page.
• Added sickness / injury in time chart.
• Added day-based navigation to the activity feed.
• Added week-based navigation to the caledar activity view.
• Added avatar/photo upload support for users, AI coaches, gear, goals, and exercises.
• Added preview of TabPFN ML-powered predictions feature with dedicated settings and predictions pages (behind feature flag).
• Added sponsor link to the application layout.
• Added Windows binary build.
• Added and expanded sport taxonomy and mappings (new meta_activity_type, many new AT_* constants,
  Strava/FIT mappings, Concept2 uses AT_ROW_ERG).
• Enriched bootstraps for activity types, exercises, and symptoms (muscle groups,
  descriptions/default weights, symptom body-part targeting) with new pytest coverage.

Changed

• Core data model changes:
  • ActivityEntity.sport renamed to ActivityEntity.activity_type_key - breaks backward compatibility.
  • Added ActivityEntity.avg_cadence and ActivityEntity.max_cadence - consider rides, rowing, swimming, and other activities.
  • Added ActivityEntity.meta_activity_type - consider ski aggregating DP/F roller ski, DP/F nordic ski, ...
  • Added ActivityEntity.tags.
  • Added ActivityEntity.is_plan.
• Reworked photo UI flows (entity photo galleries, activity/exercise photo metadata
  editor pages, markdown image support) and updated documentation site pages.
• Data migration framework:
  • Migration step: rename sport to activity type in activities and gears.
  • Migration step: merge new activity types, exercises and symptoms.
  • Expert UI tool: migration of activities from one activity type to another.
  • Python tool: re-sync Strava activities to re-new lost source attributes.

Fixed

• Activity update no longer purges source attributes (ID, descriptor and URL).
• Blobstore exception handling in activity view/update routes now only silently ignores expected BlobStoreError; unexpected errors are logged and re-raised for easier debugging.
• GPX import rewritten to be non-blocking (except upload) and to make intensive work in the asynchronous task.

Performance

• Per-request total size limit is now enforced when uploading multiple photos in a single request, preventing excessive memory use.
• EXIF metadata stripping in image processing no longer materialises the full pixel array into a Python list; metadata is cleared in-place, reducing memory allocation significantly for large images.

Documentation

• HTML documentation is newly generated from Markdown files in this repository.
• Public HTML documentation for mytral.fitness is newly generated from Markdown files in this repository.

Tests

• Added random attack which generates synthetic data of all MyTraL entities including attachments and recordings.
