Important information

Due to the changes in the Special Interest Groups (SIGs) financial management rules by ACM, last April 2024 SIGAda merged into SIGPLAN. Historically, SIGAda began in the early 1980s as a technical committee within ACM SIGPLAN (AdaTEC), and it made sense to return to that status. SIGPLAN is one of the most robust of ACMs SIGs, with thousands of members and over twenty successful conference series. See for more information on SIGPLAN.

In the context of this merge, a technical committee within SIGPLAN will be set-up, widening the mission to cover the more general area of High Integrity Languages and Technologies (HILT), consistent with the series of HILT conferences and workshops sponsored by SIGAda over the past decade.

Existing ACM SIGAda memberships were automatically converted to SIGPLAN memberships for the remainder of their term. Ada Letters concluded its print version with the December 23rd issue. It will continue electronically following that and will be available to all SIGPLAN members.

A page for the technical committee will be set up within SIGPLAN website. The SIGAda website will continue to be available, while contents are being migrated to SIGPLAN.
