Breaking changes

Boost 1.69 will be removed from Windows / Ubuntu images

Target date

Deployment of these changes will be started on 10 November and will take a few days.

The motivation for the changes

Currently, we have a lack of free space on images so we would like to deprecate old software

Mitigation ways

You can use the following snippet to install Boost 1.69.0 in runtime at the first step of the build:
Windows:

$url = "https://github.com/actions/boost-versions/releases/download/1.69.0-20200608.1/boost-1.69.0-win32-msvc14.1-x86_64.tar.gz"
(New-Object System.Net.WebClient).DownloadFile($url, "$($env:TEMP)\boost.tar.gz")
7z.exe x "$($env:TEMP)\boost.tar.gz" -o"$($env:TEMP)" -y | Out-Null
$tarPath = Get-ChildItem -Path "$($env:TEMP)" -Filter "boost-*.tar" | Select-Object -First 1
7z.exe x $tarPath -o"$($env:TEMP)/boost" -y | Out-Null
Push-Location -Path "$($env:TEMP)\boost"
Invoke-Expression .\setup.ps1

Ubuntu 1604:

$url = "https://github.com/actions/boost-versions/releases/download/1.69.0-20200608.1/boost-1.69.0-linux-16.04-gcc-x64.tar.gz"
(New-Object System.Net.WebClient).DownloadFile($url, "/tmp/boost.tar.gz")
mkdir "/tmp/boost"
tar -xzf "/tmp/boost.tar.gz" -C "/tmp/boost"
Push-Location -Path "/tmp/boost"
Invoke-Expression "bash ./setup.sh"

Ubuntu 1804:

$url = "https://github.com/actions/boost-versions/releases/download/1.69.0-20200608.1/boost-1.69.0-linux-16.04-gcc-x64.tar.gz"
(New-Object System.Net.WebClient).DownloadFile($url, "/tmp/boost.tar.gz")
mkdir "/tmp/boost"
