dbt 0.14.4

dbt 0.14.4 (November 8, 2019)

This release changes the version ranges of some of dbt's dependencies. These changes address installation issues in 0.14.3 when dbt is installed from pip. You can view the full list of dependency version changes in this commit.

Note: If you are installing dbt into an environment alongside other Python libraries, you can install individual dbt plugins with:

pip install dbt-postgres

dbt 0.13.0

dbt 0.13.0 - Stephen Girard (March 21, 2019)

Overview

This release provides a stable API for building new adapters and reimplements dbt's adapters as "plugins". Additionally, a new adapter for Presto was added using this architecture. Beyond adapters, this release of dbt also includes Sources which can be used to document and test source data tables. See the full list of features added in 0.13.0 below.

• Changelog

Installation instructions

dbt v0.13.0 is available on Homebrew, PyPi, and in dbt Cloud.

# Homebrew
$ brew install dbt

# pip
$ pip install dbt

Note: If you're upgrading from an earlier version of dbt using pip, you may need to install dbt with the -I flag. This flag is required due to changes in the structure of the dbt package.

$ pip install -I dbt

For full installation instructions, consult the docs

Breaking Changes

• Version 1 schema.yml specs are no longer implemented. Please use the version 2 spec instead (migration guide)

Stephen Girard

Can you imagine buying the Federal Reserve? That’s how rich Stephen Girard was. The First Bank of the United States, Alexander Hamilton’s brainchild, ran out its charter in 1811 and Girard decided it was a steal. Estimated to be the 4th richest American ever, he just up and bought it.

Not satisfied with one bank, Girard went for more. With the British invading in 1812, Girard put everything on the line and underwrote nearly all the US war bonds. Without this capital, we would likely all have British accents today. In return, the US made Girard a major shareholder of the Second Bank of the United States when it was founded.

Buying government bonds: dépassé.
Buying governments: branché.

Girard, who had no children, was one of America’s biggest philanthropists. He single-handedly endowed the 43-acre Girard College to educate “poor, male, white orphans,” inspired by his own hard-scrabble early life. Thankfully, its target demographic has since broadened—its first African-American student was admitted in 1968 and its first female student was admitte...

Grace Kelly

Grace Kelly (1929-1982) was a Philadelphian film actress who became the Princess of Monaco. In her early life, Kelly took an interest in acting and so moved to New York City to attend the American Academy of Dramatic Arts. As her career progressed, Kelly acted in theater productions, television shows, and ultimately gained stardom on the silver screen. She was awarded the Academy Award for Best Actress for her role in The Country Girl (1954).

While operating as a U.S. delegate to the Cannes Film Festival, Kelly came to meet the prince of Monaco. After their eventual wedding, Kelly thusly became the Princess of Monaco. In this role, Kelly adopted a life of philanthropy. Kelly founded and was involved in numerous non-profits dedicated to advancing the arts and the wellbeing of citizens of Monaco and the world alike.

Guion Bluford

Dr. Guion “Guy” Stewart Bluford Jr. is a true Philadelphian, through and through. He was born in Philadelphia, PA November 22nd, 1942 and attended Overbrook High School. He grew up in a home that encouraged academic success, which inspired him to eventually receive his Ph. D in Aerospace Engineering from the Air Force Institute of Technology in 1978.

Not only an academic, Bluford flew 144 combat missions during the Vietnam War, and earned numerous medals in the process. He became the first African American in space in 1983 as a specialist for mission STS-8 aboard the space shuttle Challenger. He was inducted into the International Space Hall of Fame in 1997 and the United States Astronaut Hall of Fame in 2010.

In addition to his professional success, Bluford has been seen as a role model for many African Americans. He has been awarded the NCAAP Image Award, Ebony Black Achievement Award and the 1991 Black Engineer of the Year award, to name a few.
