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!

Andreas, on behalf of the Agda Team
