TAME Release Notes

This file contains notes for each release of TAME since v17.4.0.

TAME uses semantic versioning. Any major version number increment indicates that backwards-incompatible changes have been introduced in that version. Each such version will be accompanied by notes that provide a migration path to resolve incompatibilities.

TAME developers: Add new changes under a "NEXT" heading as part of the commits that introduce the changes. To make a new release, run tools/mkrelease, which will handle updating the heading for you.

NEXT

This release fixes a bug caused by previous refactoring that caused unresolved externs to product an obscure and useless error for the end user.

Linker

  • Provide useful error for unresolved identifiers.
    • This was previously falling through to an unreachable! block, producing a very opaque and useless internal error message.

v17.4.2 (2020-05-13)

This release adds GraphML output for linked objects to allow us to inspect the graph.

Linker

  • Add --emit oprion to tamer/src/bin/tameld.rs that allows us to specify the type of output we want.
  • Minor refactoring.

Miscellaneous

  • Added make target to build linked GraphML files.
  • Updated make *.xmle target to explicitly state it is emitting xmle.
  • Added Cypher script to use in Neo4J after a GraphML file is imported.
  • RELEASES.md
    • Add missing link to semver.org.
    • Fix tame-core heading, which was erroneously Org-mode-styled.
    • Rephrase and correct formatting of an introduction paragraph.

v17.4.1 (2020-04-29)

This release refactors the linker, adds additional tests, and improves errors slightly. There are otherwise no functional changes.

Compiler

  • Refactor proof-of-concept dependency graph construction code.
  • Improvements to error abstraction which will later aid in reporting.

Miscellaneous

  • RELEASES.md added.
  • tools/mkrelease added to help automate updating RELEASES.md.
  • build-aux/release-check added to check releases.
    • This is invoked both by tools/mkrelease and by CI via .gitlab-ci.yml on tags.

v17.4.0 (2020-04-17)

This release focuses on moving some code out of the existing XSLT-based compiler so that the functionality does not need to be re-implemented in TAMER. There are no user-facing changes aside form the introduction of two new templates, which are not yet expected to be used directly.

tame-core

  • New rate-each template to replace XSLT template in compiler.
  • New yields template to replace XSLT template in compiler.
  • Users should continue to use rate-each and yields as before rather than invoking the new templates directly.
    • The intent is to remove the t namespace prefix in the future so that templates will be applied automatically.

Compiler

  • XSLT-based compiler now emits t:rate-each in place of the previous XSLT template.
  • XSLT-based compiler now emits t:yields in place of the previous XSLT template.
