OfflineTides 1.0.2.0 Alpha 3

Schema-qualified OfflineTides public Alpha candidate.

Built from public commit 2483ab116a983085e5dfcef47334ca1277f4e916 in CircleCI pipeline 22. Native build, package, metadata, checksum and archive-boundary gates passed for Debian 12 x86_64, Debian 13 x86_64, Ubuntu 22.04 x86_64, Ubuntu 24.04 x86_64, Debian 12 ARM64, Flatpak 25.08 x86_64, Flatpak 25.08 aarch64, Windows x86 and macOS ARM64. All nine OpenCPN API 1.21 metadata records pass the OpenCPN catalogue schema; all nine anonymous Cloudsmith package downloads were compared byte-for-byte with retained CircleCI artifacts.

Linux native CTest suites passed. Windows and Flatpak artifacts are build/package-qualified; non-Linux GUI runtime testing remains part of Alpha field testing. Plugin archives intentionally contain no tidal dataset. Download the separate authenticated global-data archive and verify it using the supplied SHA-256 manifest.

OfflineTides 1.0.2.0 Alpha 2

Second OfflineTides public Alpha candidate.

This candidate is built from public commit 9d04a377757fcf4a4a3a669bccd2cf3c7b9c39ce. Native CircleCI build, package, metadata, checksum and archive-boundary gates passed for Debian 12 x86_64, Debian 13 x86_64, Ubuntu 22.04 x86_64, Ubuntu 24.04 x86_64, Debian 12 ARM64, Flatpak 25.08 x86_64, Flatpak 25.08 aarch64, Windows x86 and macOS ARM64.

Linux native CTest suites passed. Windows and Flatpak artifacts are build/package-qualified; all non-Linux packages remain candidates for user runtime testing in stock OpenCPN. The plugin archives intentionally contain no tidal dataset. Download the separate authenticated global-data archive and verify it with the supplied SHA-256 manifest.

OfflineTides 1.0.2.0 Alpha 1

OfflineTides 1.0.2.0 Alpha 1 is the first public test release of the
OfflineTides OpenCPN plugin.

This prerelease provides offline astronomical tidal-height forecasts using a
self-contained global .xtdt data package. Forecasts can be displayed relative
to Chart Datum or model mean sea level, with datum and uncertainty information,
high/low-water events, selectable dates and locations, native OpenCPN station
comparison, and JSON/CSV export.

Qualified plugin packages are included for:

• Ubuntu 24.04 x86_64
• Ubuntu 22.04 x86_64
• Debian 13 x86_64
• Debian 12 x86_64

The separate offlinetides-global-data-1.0.0-alpha1.tar.gz archive contains the
global forecast data. Extract the archive and select the enclosed .xtdt file
from OfflineTides using Open .xtdt package....

OfflineTides is an alpha-stage secondary planning aid. Its astronomical
forecast does not account for live weather surge, atmospheric pressure, river
flow, waves, or other short-term non-tidal effects. It is not a substitute for
official publications, observations, prudent navigation, or maintaining a safe
under-keel clearance.

The public data archive contains quantised derived harmonic coefficients and
the runtime manifest required by the plugin. It contains no raw third-party
model dataset or publication-derived tide tables. Checksums for every release
asset are provided in OfflineTides-1.0.2.0-alpha1-SHA256SUMS.
