Arquivo.pt released a new version of its service on the 25th of January 2017.
The new version named PyCDX introduces significant improvements in the replay quality of the preserved pages.
These improvements resulted from the adoption of PyWb technology developed by Ilya Kreymer.
The replay of the preserved pages is now more comprehensive, with the loading of additional images, PDF, CSS, and other Web content that previously were not reproduced.
Arquivo.pt released a new version on the 7th of November 2016.
The new version named Hercules presents design improvements, specially in the user interface for the replay of preserved Web pages, such as:

The Arquivo.pt made 2 crawls of Web pages related with the Portuguese Presidential Elections of 2016.
We had appealed to the community contribution by suggesting Web pages related with the Presidential Elections of 2016 in order to archive it.
We made 2 crawls, during and after the election campaign period, using the list of 284 Web pages suggested by the community, archiving a total of 551 672 Web resources, that occupy 7 GB.
It were collected Web pages such as the official ones from the running candidates, from political parties, news in the media about the elections, blogs, opinion articles.
The Arquivo.pt respects an embargo period of 1 year, and for that reason the archived collection will only be avaliable by the end of 2016.
However you can consult now some archived Web pages from the previous Portuguese Parliamentary Elections such as:

On the 12th January 2016 we have issued a press release about Arquivo.pt, where we explain our service, its history, present, colaborations and future challenges.
The Arquivo.pt is a free of charge service, that allows the search of Web archived data since 1996. The investigation infrastructure of Arquivo.pt is mainly focused on the preservation of relevant content for the portuguese community.
There are currently about 2700 milions of archived files, which correspond to 95 TB of information and any person can suggest interesting sites to be archived by simply going to https://arquivo.pt/suggest.
In 2015, the Arquivo.pt has collected 580 milion files for preservation, and the search service has registered an average of 3 692 users per month, from which 90% are new users.
In 2016 the Arquivo.pt will make avaliable the access to archived Web pages from the .eu domain and the Arquivo.pt team will work on a prototype that will allow the search and visualization of archived images.
We produced the following dissemination materials:
Your collaboration to disseminate Arquivo.pt is essential for this service to become useful to an increasing amount people.
Ask us for materials to disseminate Arquivo.pt at your institution or event. We will send it to you free of charge.
Thank you.
The name given to this release was opportunely Fénix (Phoenix). 20 cases that originated the following improvements were resolved:
We inform that we migrated our open source project to GitHub: pwa_technologies where you can find more details about the Fénix version.
Comments and suggestions are most welcome!

News updated on August 1, 2019.
The .EU domain is commonly used to reference sites related to Europe. The strategy adopted to archive the World Wide Web has been delegating the responsibility of each domain to the respective national archiving institutions. However, the .EU domain fails to fit in this model because it covers multiple nations. Thus, the preservation of .EU sites was not been yet assigned and undertaken by any institution.
RESAW is an European network that aims to create a Research Infrastructure for the Study of Archived Web Materials (resaw.eu).
Arquivo.pt performed a first attempt to crawl and preserve web sites hosted under the .EU domain within the scope of RESAW activities. This first crawl began on the 21 November 2014 and finished on the 16 December 2014.
We performed 2 more crawls of the .EU domain. All the crawls were indexed and became searchable through Arquivo.pt one year after its finish date. Moreover, we made available a prototype that enables focused search over the .EU crawls which demonstrates the simplicity of creating search engines that targeted specific collections through the usage of the “collection” search parameter.
Collaborations with researchers interested on studying the collected web data sets or crawl logs are welcome.

It is impossible to preserve the Web without the authors collaboration.

The paper Trends in Web characteristics written by João Miranda and Daniel Gomes, was distinguished as the 2nd best paper presented at the 7th Latin American Web Congress.
The paper presents results on the evolution of Web characteristics, derived from the comparison of a crawl performed by the PWA in 2008 with previous studies.
