• James: Added first_row, second_row and last_row to Table APIs. Update rename_columns to new API design, add first_row, second_row and last_row functions to the table. #5719
• James: Design for writing data control https://github.com/enso-org/design/pull/53
• James: Resolve issues with table and error visualization. Stability improvements in visualizations. #5760
• James: Resolve issue with expectText method returning wrong error messages and crashing on null. Adjust generateCheckedArgumentRead to return correct expected type #5769
• James: Looking into derived columns in-memory and in-database.
• Radek: Problem handling on Text.encoding and decoding. Review Text encoding/decoding problem handling #5701
• Radek: Started working on the problem handling for File and Data read.
• Greg: Completed updating Text.match, Text.find and Text.find_all. Wip/gmt/match find only text #5721
• Greg: Working on bringing in Truffle Regex and updating Regex.compile, match, find and find_all.
• Jaroslav: Fixed File.new NullPointerException. File.parent can return Nothing #5699

• Jaroslav: Adjusting tagValues to not include single constructor (e.g. Table.Value). Offer no suggestion for single constructor #5747
• Jaroslav: Work on the Suggestion DB.
• Hubert: Continued work on processing only requested modules when resolving imports. Optimize import/export resolution #5700
• Pavel: Working on If-then-else performance issue. If cascades 5x slower than case-of due to limit of recursive inlining #5709
• Pavel: Looking at performance of Number.is_nan - separating NaN to own type. NaN is a new builtin type #5744
• Pavel / Jaroslav: Discussion on sorting and NaN - adding in partial ordering support.

Fixed the visualization for 2D vectors.

• Mentioned previously, was transposed.
• Also fixes nested vectors.

[jdunkerley]

Updated the rename_columns API to a new simpler Map and Vector based approach.

• More like select APIs.
• Uses the map to allow mixing and matching index or name.
• Simpler control for By_Name.

[jdunkerley]

Added first_row, second_row and last_row to Table APIs.

• Adds short hand to get a single row,
• Returned as a row object.
• Will materialise just what is needed in DB
• InDB scans a reader forward as many drivers don't allow random access for last_row.
