Desenvolvedores da linguagem Python tomaram a decis\u00e3o<\/a><\/noindex> mudar para um novo esquema<\/a><\/noindex> de lan\u00e7amento. As novas vers\u00f5es significativas da linguagem agora ser\u00e3o lan\u00e7adas uma vez por ano, em vez de a cada um ano e meio, como era anteriormente. Assim, o lan\u00e7amento do Python 3.9 pode ser esperado para outubro de 2020. O tempo total de desenvolvimento de uma vers\u00e3o significativa ser\u00e1 de 17 meses.<\/p>\n

O trabalho em uma nova branch come\u00e7ar\u00e1 cinco meses antes do lan\u00e7amento da pr\u00f3xima branch, durante sua transi\u00e7\u00e3o para a fase de beta testing. Em seguida, por sete meses, a nova branch estar\u00e1 na fase de lan\u00e7amentos alfa, durante a qual novas funcionalidades ser\u00e3o adicionadas e corre\u00e7\u00f5es de bugs realizadas. Depois disso, durante tr\u00eas meses, o teste das vers\u00f5es beta ser\u00e1 realizado, onde a adi\u00e7\u00e3o de novas funcionalidades ser\u00e1 proibida e toda a aten\u00e7\u00e3o ser\u00e1 dada \u00e0 corre\u00e7\u00e3o de bugs. Os dois \u00faltimos meses antes do lan\u00e7amento a branch estar\u00e1 na fase de candidato a lan\u00e7amentos, onde a estabiliza\u00e7\u00e3o final ser\u00e1 realizada.<\/p>\n

Por exemplo, o desenvolvimento da vers\u00e3o 3.9 come\u00e7ou em 4 de junho de 2019. O primeiro lan\u00e7amento alfa foi publicado em 14 de outubro de 2019, e o primeiro lan\u00e7amento beta est\u00e1 previsto para 18 de maio de 2020. Em agosto, ser\u00e1 formado o candidato a lan\u00e7amentos, e em 5 de outubro ocorrer\u00e1 o lan\u00e7amento.<\/p>\n

\"Python<\/a><\/noindex><\/center><\/p>\n

Ap\u00f3s o lan\u00e7amento, a branch ser\u00e1 totalmente suportada durante um ano e meio, ap\u00f3s o que mais tr\u00eas anos e meio ser\u00e3o dedicados \u00e0 forma\u00e7\u00e3o de corre\u00e7\u00f5es para vulnerabilidades. Assim, o tempo total de suporte ser\u00e1 de cinco anos. Na primeira fase de suporte, bugs ser\u00e3o corrigidos e atualiza\u00e7\u00f5es ser\u00e3o lan\u00e7adas aproximadamente a cada dois meses, com a prepara\u00e7\u00e3o de instaladores para Windows e macOS. Na segunda fase, os lan\u00e7amentos ser\u00e3o formados conforme necess\u00e1rio para a corre\u00e7\u00e3o de vulnerabilidades e ser\u00e3o disponibilizados apenas na forma de c\u00f3digo fonte. <\/p>\n

Observa-se que o novo ciclo de desenvolvimento permitir\u00e1 uma transi\u00e7\u00e3o previs\u00edvel nas fases de teste alfa e beta, al\u00e9m de saber exatamente o tempo necess\u00e1rio para a forma\u00e7\u00e3o do lan\u00e7amento, o que proporcionar\u00e1 a oportunidade de sincronizar o desenvolvimento de seus produtos com os novos ramos do Python. Um ciclo de desenvolvimento previs\u00edvel tamb\u00e9m simplificar\u00e1 o planejamento do desenvolvimento do Python, e um lan\u00e7amento mais frequente de novos ramos acelerar\u00e1 a entrega de novas funcionalidades aos usu\u00e1rios, reduzindo o volume de mudan\u00e7as em cada ramo (lan\u00e7amentos mais frequentes, mas com menos novidades em cada lan\u00e7amento). A extens\u00e3o e a fragmenta\u00e7\u00e3o da fase de teste alfa permitir\u00e1 rastrear a din\u00e2mica do desenvolvimento e integrar as inova\u00e7\u00f5es de forma mais suave, evitando a correria antes do lan\u00e7amento beta, durante o qual os desenvolvedores se esfor\u00e7avam para finalizar as inova\u00e7\u00f5es no \u00faltimo minuto, para que n\u00e3o fossem adiadas por 18 meses at\u00e9 o pr\u00f3ximo ramo.<\/p>\n
