Daily Digest: 2026-05-04

[github-actions]

We are given a daily digest for 2026-05-04. We need to structure the response as:

1. Highlights (1-3 bullet points of the most important changes)
2. Code Changes (summarize commits by theme, not individually)
3. Pull Requests (merged, opened, pending review)
4. Issues (new, closed, total open)
5. Repository Health (stars, forks, CI status)
6. Action Items (anything that needs attention: failing CI, stale PRs, unanswered issues)

Let's break down the provided data:

CI Status (latest runs on main)

• Daily Project Digest [2026-05-04T09:12:24Z] (this is the digest generation, not a build)
• success — Build, Test & Lint [2026-05-04T08:17:32Z]
• success — Push on main [2026-05-04T08:03:05Z]

So CI is passing.

Dependency Changes (last 5 commits)

• None.

Now, let's structure the digest:

Highlights

We need 1-3 bullet points of the most important changes.

Looking at the commits and closed issues, some important fixes:

• Fixed the SET command implementation (issue REPL: SET key = value listed in HELP but not implemented (scaffolding only) #471) which was listed in HELP but not implemented.
• Fixed the CATALOG.ASSOCIATIONS table (issue CATALOG.ASSOCIATIONS table missing from catalog #419) which was missing.
• Fixed the performance issue in mxcli report (issue mxcli report hangs indefinitely after catalog load #397) that was hanging indefinitely.
• Fixed the DataGrid2 column name derivation (issue DESCRIBE PAGE widget names don't match ALTER PAGE identifiers #116) which was a long-standing issue.

Also, note that many documentation updates were made, but for a daily digest, the fixes might be more highlighted.

However, the digest is for the project maintainers, so we might highlight both the fixes and the documentation work.

But let's pick the top 3:

1. Fixed critical bugs: SET command implementation (REPL: SET key = value listed in HELP but not implemented (scaffolding only) #471), catalog tables (CATALOG.ASSOCIATIONS table missing from catalog #419), and report performance (mxcli report hangs indefinitely after catalog load #397).
2. Improved DataGrid2 handling for ALTER PAGE (DESCRIBE PAGE widget names don't match ALTER PAGE identifiers #116) and fixed cross-module associations in CREATE object actions.
3. Updated Mendix versions to include 11.10.0 and updated nightly workflows.

Alternatively, we can note the volume of fixes and documentation.

But the instruction says "most important changes". Since the project is a CLI tool, the functional fixes are important.

Let's go with:

• Fixed SET command implementation (issue REPL: SET key = value listed in HELP but not implemented (scaffolding only) #471) and catalog table issues (CATALOG.ASSOCIATIONS table missing from catalog #419, mxcli report hangs indefinitely after catalog load #397) improving core functionality.
• Resolved DataGrid2 column mismatch (issue DESCRIBE PAGE widget names don't match ALTER PAGE identifiers #116) and cross-module association preservation in CREATE object actions.
• Updated Mendix version support to 11.10.0 and made numerous documentation improvements for strategic positioning.

Code Changes

Summarize by theme:

• Version Updates: Updated Mendix versions in nightly workflow and to include version 11.10.0.
• Bug Fixes:
  • Implemented session-level SET command and fixed JSON format persistence (addressing REPL: SET key = value listed in HELP but not implemented (scaffolding only) #471).
  • Fixed catalog tables (ASSOCIATIONS, CONSTANTS, OBJECTS) to return data (CATALOG.ASSOCIATIONS table missing from catalog #419).
  • Optimized mxcli report by replacing O(N²) lookup with direct unit lookup (mxcli report hangs indefinitely after catalog load #397).
  • Corrected DataGrid2 column name derivation for ALTER PAGE (DESCRIBE PAGE widget names don't match ALTER PAGE identifiers #116).
  • Preserved cross-module associations in CREATE object actions.
  • Fixed various panics and SIGSEGVs in workflow, REST, and nanoflow handling.
  • Addressed test failures for SOAP, workflow, and nanoflow doctypes.
  • Fixed git error propagation in diff-local.
  • Escaped single quotes in XPath constraints for DESCRIBE ENTITY.
  • Fixed expression split flows and TitleOverride in microflows.
• Documentation:
  • Added bug tests and skill docs for DataGrid2 issue.
  • Enhanced strategic positioning documentation with sections on compiler evolution, generation time, workflow phases, model tier, and BSON benchmark.
  • Corrected various claims (discoverability, document-read) and refactored sections for clarity.

Pull Requests

• Merged: None in the last 24h.
• Opened: None in the last 24h.
• Pending Review: 7 open PRs (ranging from feat: add modelsdk — auto-generated type-safe model SDK #335 to fix: rejoin empty custom error handler at IF ELSE first activity #504), including features for inheritance split, expressions in add-to-list, modelsdk, and fixes for custom error handler and merge emission.

Issues

• New: 0
• Closed: 12 (including Daily Digest: 2026-05-03 #501, Image collection CREATE OR REPLACE returns 'already exists' instead of replacing #477, REPL: SET key = value listed in HELP but not implemented (scaffolding only) #471, RENAME nanoflow allows creating duplicates (no collision check) #432, GRANT with XPath WHERE clause produces empty access rules (permissions lost) #431, PANIC nil pointer dereference in visitor_workflow.go:145 on ALTER WORKFLOW DROP BOUNDARY EVENT #430, SIGSEGV in visitor_rest.go:386 on end resource syntax in CREATE PUBLISHED REST SERVICE #429, CATALOG.ASSOCIATIONS table missing from catalog #419, mxcli report hangs indefinitely after catalog load #397, Microflow description of Aggregate functions containing expressions is wrong #241, Feature request: CREATE PUBLISHED REST SERVICE support in MDL #135, DESCRIBE PAGE widget names don't match ALTER PAGE identifiers #116)
• Total Open: 1 (from repository stats)

Repository Health

• Stars: 77
• Forks: 25
• Watchers: 7
• CI Status: All latest runs on main are success (Build, Test & Lint and Push on main). The Daily Project Digest run is also success but that's the digest generation.

Action Items

• Stale PRs: There are several open PRs that have been open for a while (e.g., feat: add modelsdk — auto-generated type-safe model SDK #335 from 2024? We don't have dates, but the issue numbers are low). However, without dates we can't tell if they are stale. But note: the oldest open PR is feat: add modelsdk — auto-generated type-safe model SDK #335 (feat: add modelsdk) which is likely old. We should check if they need attention.
• CI Status: All green, so no failing CI.
• Unanswered Issues: Only 1 open issue (from stats). We don't know what it is, but it's low.

However, the digest doesn't provide the current open issue. We know from the stats that there is 1 open issue. We should note that.

But the action items should be things that need attention. Since CI is passing and there are no new issues,
