The Agda Team is not very pleased to announce that it has to retract Agda 2.6.4.2 due to a regression concerning `with`: https://github.com/agda/agda/issues/7148 So, please do not install it, wait for the next release. On 2024-02-24 12:20, Andreas Abel wrote:
Dear all,
The Agda Team is pleased to announce the release of Agda 2.6.4.2.
Agda 2.6.4.2 is a bugfix release over Agda 2.6.4.1:
- Fix an inconsistency in Cubical Agda related to catch-all clauses. - Fix some internal errors. - Fix an issue with `opaque`. - Fix building with cabal flag `-f debug-serialisation`.
# GHC supported versions
Agda 2.6.4.2 has been tested with GHC 9.8.1, GHC 9.6.4, 9.4.8, 9.2.8, 9.0.2, 8.10.7, 8.8.4 and 8.6.5 on Linux, macOS and Windows.
# Installation
Agda 2.6.4.2 can be installed using cabal-install or stack:
1. Getting the tarball
$ cabal update $ cabal get Agda-2.6.4.2 $ cd Agda-2.6.4.2
2. a. Using cabal-install
$ cabal install -f +optimise-heavily -f +enable-cluster-counting
2. b. Using stack
$ stack --stack-yaml stack-a.b.c.yaml install --flag Agda:optimise-heavily --flag Agda:enable-cluster-counting
replacing `a.b.c` with your version of GHC.
The flags mean:
- optimise-heavily: Turn on extra optimisation for a faster Agda. Takes large resources during compilation of Agda.
- enable-cluster-counting: Enable unicode clusters for alignment in the LaTeX backend. Requires the ICU lib to be installed and known to pkg-config.
These flags can be dropped from the install if causing trouble.
# Standard library
You can use standard library v1.7.3, v2.0 or the `master` branch of the standard library with Agda 2.6.4.2. This branch is available at
https://github.com/agda/agda-stdlib/
# Fixed issues over Agda 2.6.4.1

Enjoy Agda 2.6.4.2!
