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.
[semantic versioning]: https://semver.org/
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.
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.
