v0.4.0

TALA 0.4.0 is a massive improvement in layout positions of a wide range of diagrams.

Improvements 🧹

• Unconnected nodes and subgraphs are packed more tightly together
• Containers of similar sizes with indirect connections are aligned better
• Some diagrams escape local minimas better
• Nodes connected on both sides are more equidistant to both
• Cluster edge labels prioritize not intersecting with other cluster edges
• Node labels reposition to avoid overlapping with icons
• Node icons reposition to avoid overlapping with fixed labels
• Multiple edges between nodes are now ordered (left-right and top-down) by the order they were declared
• Edge routes between grid cells avoid node labels
• Edge routes consider paths that go through "invisible" nodes and edges (e.g. zero opacity)
• When only one of width or height is specified for a container, nodes will full up better to reduce unused space
• Tree structures are built more symmetrically
• Containers with edges going into its children are pulled closer together to the other edge endpoint
• Clusters of nodes are oriented more reasonably to facilitate better routes
• Clusters routes more often converge on a single point in the middle to form the "fork" aesthetic
• Node labels are positioned in areas of more space
• Edge labels avoid fixed node icon positions

Bugfixes ⛑️

• Fixes extra warnings that appeared with an invalid token
• Fixes panic when edges were defined between actors in different sequence diagrams
• Fixes custom label positions and icon positions not working for nodes in tree structures
• Disallow edges with different styles (e.g. stroke colors) from sharing routes
• Some direct straight routes weren't being considered between two non-diagonal nodes

v0.3.14

This version replaces 0.3.13 as it had broken compatibility with D2. Requires D2 0.6.5.

Improvements 🧹

• Cluster edge labels prioritize not intersecting with other cluster edges.

Bugfixes ⛑️

• Fixes plugin compatibility
• Fixes extra warnings that appeared with an invalid token

v0.3.13

Improvements 🧹

• Containers expand to fit long child labels
• Edge labels on cluster edges are placed along the edges more symmetrically
• More symmetrical placements are found for shapes connected to multiple other shapes
• More aligned layouts in graphs where multiple shapes in a container are connected to a shape at the parent level
• Connections between two shapes of different container levels take the direction of the least nested shape
• Connections made across grid diagrams and sequence diagrams are now routed with TALA's edge routing
• Improves edge routing to allow more bidirectional edges to overlap when they share a node and have matching arrowheads
• Less memory used when many subgraphs

Bugfixes ⛑️

• Fixes overlapping routes for certain trees with mixed arrow directions
• Label for the first step of multiple connected steps with "multiple" set is centered
• Connections to concave shapes like "step" are more precisely connected when multiple or 3d set (previously they jutted into the shape a little)
• Prevents edge case where a connection with a long connection label could overlap shapes
• Fixes an edge case where two connected nodes in different containers were suboptimally aligned

v0.3.12

Improvements 🧹

• Connections can now route through shapes at a fixed position that block access to another shape
• Layout is up to 74% faster on very large diagrams

Bugfixes ⛑️

• Fixes a rare scenario where containers could end up overlapping
• Fixes a bug where shapes are grown to fit connections despite having width or height set

v0.3.11

Improvements 🧹

• Connections from a sql_table column and a non-column will now route to the specific column
• Reduce scenarios where nodes could end up far from a connected node with a fixed position
• Reduce rare scenarios where a subgraph within a container could end up far from other subgraphs connected to shapes outside the container

Bugfixes ⛑️

• Fixes a rare bug resulting in non-deterministic layouts
• Fixes scenarios where trees could become very wide with excessive spacing between subtrees

v0.3.10

Features 🚀

• Configure timeout value with D2_TIMEOUT env var. (requires D2 0.6.0)

Improvements 🧹

Bugfixes ⛑️

• Fixes grid label font size
• Prevents scenarios where bidirectional edges with different arrowheads could overlap each other
• Fixes a rare bug where shapes in a tree layout could sometimes be misplaced

v0.3.9

Improvements 🧹

• Layout is up to 3x faster and uses as little as 1/3 the memory after many optimizations

Bugfixes ⛑️

• Compatability with D2 0.5

v0.3.8

Features 🚀

• Containers respect width and height settings, though they will expand to fit content if needed

Improvements 🧹

• Node placement is up to 2x faster
• Avoids overlapping edges when they have different arrowheads
• direction keyword now affects bidirectional edges
• Spacing between nodes ensures that labels will fit
• Edges stick to outer bounds of shapes with 3d or multiple
• Improves layouts for clusters with both icons and labels
• Improves edge balancing to look more symmetrical

Bugfixes ⛑️

• Fixes shape and connection labels potentially overlapping arrowhead labels
• Fixes a bug with arrowhead labels on the - end of a connection
• Fixes container shapes sometimes swapping positions with another shape errantly

v0.3.7

Features 🚀

• Nodes are expanded to aesthetically fit all connections if not enough room with default dimensions
• Arrowhead labels are considered in autolayout and avoid overlaps as much as possible

Improvements 🧹

• Pairs of nodes prefer horizontal arrangements given multiple connections with labels

Bugfixes ⛑️

• Fixes a rare bug using near to a node in a tree structure
• Fixes a rare bug positioning nested node clusters
• Fixes a rare panic involving edge labels

v0.3.6

Compatible with D2 0.4.1 onwards.

Improvements 🧹

• Improves edge routing between hierarchies and non-hierarchies
