Graphannis

Changed

- Compile releases on Ubuntu 20.04 instead of 18.04, which means the minimal
GLIBC version is 2.31. This is necessary, since GitHub actions deprecated this
Ubuntu version.


Fixed

- Update quick-xml to version 0.28 to avoid issues in future Rust versions
- Update sstable to version 0.11 to avoid issues in future Rust versions
- Update actix-web to version 4 to avoid issues in future Rust versions
- Update config crate to version 0.13 to avoid issues in future Rust versions
- Update diesel to version 2.0 due to issue in sqlite dependency

Fixed

- Importing a corpus with a relative path directly under the current working
directory would fail if the corpus has linked files.
- Output of data items in GraphML for node/edge annotations could be unordered
and cause test failures if comparing GraphML files.

Fixed

- Update smartstring crate to version 1 to avoid issues with newer Rust
versions.

Fixed

- After re-using a deleted symbol ID (used in the annotation storage), the
retrieved value was empty.

Fixed

- When importing relANNIS corpora with sub-corpora, add the `PartOf` edge to the
parent corpus node of the document or sub-corpora, but not automatically to
the top-level corpus.

Added

- Allow to configure how spans should be interpreted in the view when the token
layer is representing a timeline with the `timeline_strategy` parameter in the
`view` section of the corpus configuration. This allows the view to
reconstruct an implicit relation between spans and their segmentation nodes
(which is not possible to represent in the legacy relANNIS data model). New
corpora should use explicit `Coverage` edges between spans and their
segmentation nodes, but in order to maintain backward compatibility with
relANNIS, we need to support these older corpus configuration values
(`virtual_tokenization_mapping` and `virtual_tokenization_from_namespace`),
which only affect the display of the corpora.
